Relieving Pressure

Before you do anything, you need to make sure your hydraulic system is depressurized. Working on a pressurized system is not only risky, it’s dangerous.

Check for live loads: Before you start, make sure there are no live or heavy loads on the hydraulic components. Live loads can move suddenly and cause unintended movement in the hydraulic system.

Use a pressure gauge: Don’t just rely on the system indicator; use a pressure gauge to double-check that the system is fully depressurized. This is your failsafe and should never be omitted.

Manual relief valves: Some systems have manual relief valves to safely relieve pressure. Learn where these valves are located and how to use them.

Pre-Disassembly Steps

Before diving into the nitty-gritty of hydraulic fitting maintenance, preparation is key. The pre-disassembly steps are critical to completing the maintenance process smoothly and efficiently.

Labeling Components

Labeling each component to be disassembled will help you keep track of the part and its corresponding location. This will make reinstallation a breeze and reduce the risk of errors.

How to do it: Use durable, waterproof labels and a permanent marker to clearly mark each part. If possible, take a photo for reference.

Pro tip: Create a numbering system or chart to help you remember the order of parts, especially when working with complex assemblies.


Having all the necessary tools on hand minimizes downtime and ensures that you are prepared for any unexpected problems. Often, the specific tools depend on the job.

Adjustable Wrenches or Sockets

This is your go-to tool for loosening and tightening fittings. They come in a variety of sizes to fit different types of hydraulic components.

Safety goggles and gloves

Goggles protect your eyes from splashing hydraulic fluid, while gloves protect your hands from possible cuts and chemical exposure.

Hydraulic Fluid

Hydraulic fluid is required to replenish the system after maintenance. Always use the manufacturer’s recommended grade. Keep extra hydraulic fluid on hand for emergencies.

Drain pan

A drain pan collects spilled hydraulic fluid during maintenance, keeping your work area clean and safe. You can choose a drain pan with a spout for easy disposal of collected fluid.


Wipes are essential for cleaning up spills and wiping down parts before reassembly. You can use industrial-grade wipes that can handle hydraulic fluid and other chemicals.

Optional: Thread Sealant Remover

If you are using older fittings with thread sealant, the remover will make the disassembly process smoother. Be sure to read the instructions before use to ensure the remover is compatible with your system materials.

Checklist: Create a quick checklist to review before you begin. This will ensure that you haven’t overlooked any critical steps or tools.

Replacement process

In the world of hydraulics, replacing old or damaged hose fittings is a common and critical task. A faulty fitting can jeopardize an entire hydraulic system, leading to inefficiencies and potential safety hazards. We’ll guide you through the process of removing old hydraulic hose fittings safely and efficiently.

Safety First

Before touching the wrench, make sure you have taken all necessary safety precautions. Wear safety goggles and gloves to protect yourself from splashing hydraulic fluid and sharp edges. In addition, make sure that the hydraulic system is completely depressurized to avoid any high-pressure hazards.

Loosening process

Place a wrench or socket on the fitting and turn counterclockwise. Apply steady pressure; erratic movements may damage the threads or the fitting itself. If the fitting does not move, do not force it to turn. Forcing a stuck fitting can cause damage to the threads and make removal more difficult.

For stubborn fittings, you can use penetrating oil. Apply a small amount around the joint and let it sit for a few minutes. This will help loosen any corrosion or scale buildup.

Once the penetrating oil has done its job, try loosening the joint again. You should find it easier to turn. Continue to turn it counterclockwise until it is loose enough to remove by hand. At this point, you can safely remove the fitting while making sure the area remains clean and ready for the new fitting to be installed.

Draining the hydraulic fluid

Start by placing absorbent pads or towels around the work area to catch any accidental spills. This extra layer of protection goes a long way in keeping the work area clean. Then place a drain pan directly below the hose and fitting area. Make sure it is large enough to catch all the fluid to be drained. The drain pan will catch the hydraulic fluid and prevent it from contaminating the work area.

At first you’ll want to start by slowly loosening the fitting using an adjustable wrench. Turn it counterclockwise until you see the fluid start to drain into the sump. Wait until all fluid has drained before completely removing the fitting. Rushing this step can result in spills and potential hazards.

Collect the hydraulic fluid draining from the sump and pour it into a sealable container. Dispose of it according to your local environmental regulations to ensure compliance.

You need to inspect the hose and surrounding components for signs of wear, corrosion or damage. These signs indicate the need for further replacement or repair. Use a flashlight to improve visibility, especially in tight or dark spaces. Take the time to thoroughly inspect each component and, if possible, take photographs for future reference.

Cleaning Before Installation

Clean mounting areas and threads ensure secure, leak-free connections, which are critical to system efficiency and safety.

You can use a wire brush or thread sealant remover to clean the threads of the hose and its connecting parts. This will remove any old sealant, dirt, or corrosion that may affect the new fitting.

Keep in mind to always turn the brush or apply the remover in the direction of the threads. This ensures that you don’t damage the threads, which can make installation difficult and unsafe.

Installing Fittings and Hoses

Installing new hydraulic hose fittings is a task that requires precision, attention to detail, and proper technique. This guide will walk you through the critical steps of installing a new fitting to ensure efficient and safe operation of your hydraulic system.

Preparing a New Fitting

Preparing clean fittings ensures a safe, leak-free connection and sets the stage for optimum system performance.

You will need to put on clean gloves and wipe the new fitting with a lint-free cloth to remove any manufacturing residue or contaminants. If the fitting has been stored for some time, a quick rinse with a suitable solvent is recommended.

Apply thread sealant

Thread sealant enhances the seal between threaded parts, preventing leakage and ensuring a secure connection. Thread sealant should be used if recommended by the manufacturer or if you are using a high pressure system to prevent leakage from the hydraulic system. Avoid applying too much as excess sealant can enter the hydraulic system and cause problems.

Tighten Fittings

Proper tightening ensures that fittings are secure and minimizes the risk of leaks or dislodging under pressure. Use an adjustable wrench to turn the fitting clockwise until tight, then a final quarter turn to ensure a secure fit. Never over-tighten fittings. Excessive force can damage the threads and compromise the integrity of the connection.

Post-Installation Inspection

Post-installation inspections are critical to ensure that your new fitting is secure and your hydraulic system is fully functional. The following describes how to perform the inspection.

Pressure Test

You will need to re-pressurize the hydraulic system and monitor the pressure gauge. The pressure should stabilize at the system’s normal operating level. If not, there may be a leak or other problem that needs to be addressed. The pressure test verifies that the new fitting can withstand the operating pressure of the hydraulic system without failure.

It is a good idea for the operator to stand away from the fitting at all times during the pressure test to avoid injury in the event of a failure.

Leak Check

After the pressure test, visually inspect the fitting and surrounding area for traces of hydraulic fluid. You can also check for leaks using leak detection fluid or even cardboard.

Perform a leak check immediately after installation and after the system has been in operation for some time. Some leaks only become visible when the system is in constant use.

System Checks

New fittings are only one part of a complex hydraulic system. Ensuring that the entire system is functioning properly is critical to overall performance and safety. The hydraulic fluid level should be checked and topped up if necessary. In addition, check other system components such as hoses, valves and pumps to ensure they are in good condition.

Pre-crimping Preparation

Preparation is key before you begin crimping. Proper preparation ensures a secure, long-lasting connection that can withstand the stresses of a hydraulic system.

Choosing the right hose

Compatibility is paramount: Make sure the hose is compatible with the hydraulic fluid being used. Mismatches can lead to leaks and even system failure.

Value for money: Don’t settle for less. Consider the durability of the hose and how often it needs to be replaced. Sometimes spending a little more up front can save you money in the long run.

Choosing fittings

Material Matters: Fitting material should be compatible with hydraulic fluid. Stainless steel is usually a good choice.

Size and shape: Make sure the size and shape of the fitting matches the hose. This will ensure a tight, leak-free connection.

Value for money: As with hoses, consider the long-term value. A slightly more expensive but more durable fitting may be a wise investment.

Marking depth

Before inserting the hose into the fitting, apply some lubricant to ease the process. Push the hose into the fitting as far as it will go, then mark the depth with chalk or a marker. This way, you can double-check after crimping to make sure it’s safe.

Cleaning is critical

Before proceeding, clean the hose and fittings to remove any contaminants. This reduces the risk of system failure due to dirt or debris.

Loading specifications

Before starting to crimp, ensure that the correct specification has been loaded into the crimper by selecting the correct die and ferrule for the hose diameter.

Crimping Process


Ensure that the crimping machine is ready for use before touching the hydraulic hose.

Calibration: This is not a simple operation. Calibrate the machine for the hose and fittings being used. An improperly calibrated machine can result in a weak crimp, which can lead to failure.

Safety check: Make sure all safety features are enabled. Wear your goggles and gloves for your personal safety.


Before you even think about crimping, it’s important to align first. Place the hose and fittings side by side to ensure they are perfectly aligned. This step is critical because even a slight misalignment can result in an uneven crimp. Uneven crimping isn’t just an aesthetic issue; it can lead to leaks and even catastrophic system failure.


When you begin inserting the fitting, lubricate both ends of the hose. Not only will this ease insertion, but it will also minimize wear and tear on the hose and fitting. After inserting the hose into the fitting, pause and double check the alignment. If all is well, you can use a cork hammer to gently tap the fitting to make sure it is secured at the insertion mark you made earlier.

Machine Operation

Now that the hose and fitting are fully aligned and inserted, the next step is the big one – crimping. Place the hose and fitting into the crimping machine, making sure the fitting is positioned just above the mold. Double check any other settings on the machine before pressing the crimp button. Crimp pressure must be just right; crimping too tightly or too loosely can lead to hose failure. If you are unsure of the crimping procedure or machine parameters, consult your supplier immediately. It is better to ask than to risk a failed crimp.

Quality check

You have completed the crimping, but it is not over yet. Before removing the hose from the machine, grab a caliper and measure the crimp diameter.  Compare the measurement to the specifications provided by the supplier or manufacturer. If the numbers match, you have successfully completed a perfect crimp. If they don’t match, you’ll need to adjust the machine settings and try again. 

Post-crimp Inspection

You have calibrated the machine, aligned the hoses and fittings, and successfully completed the crimp. But the job isn’t over yet. The post-crimp inspection is the last line of defense against potential system failure. It’s the final and critical step in ensuring the safety, efficiency and longevity of your hydraulic system. Let’s take a closer look.

Visual Inspection

Inspect the crimp: Carefully inspect the crimp to make sure it is even all around. Uneven crimps are not only a cosmetic problem, they also create weak points that can fail under pressure.

Installation position: Carefully check the position of the joint. If it moves during the crimping process, the crimp is not perfect.

 Check the hose for any visible signs of wear, such as cracks or abrasions. A damaged hose is a ticking time bomb that could result in system failure or injury to personnel.

Measurement Verification

Crimp Diameter: Use calipers to measure the crimp diameter. Compare this measurement to the manufacturer’s specifications to ensure it is within acceptable limits.

Hose Length: Check the length of the hose to make sure it has not stretched or contracted during the crimping process. Any noticeable change in length may affect system performance.

Installation Depth: Refer to markings made prior to crimping. Ensure that the fitting is inserted at the correct depth as this is essential for a secure fit.

Pressure Test

Initial Test: Start with a low-pressure test to identify any immediate problems, such as leaks or weak spots. This is the first opportunity to identify problems before they escalate.

High-Pressure Test: Gradually increase the pressure to the hose’s maximum working limit. Look out for any leaks or deformation that may occur under high pressure.

Continuous Pressurization: Maintain the maximum pressure for a set period of time (usually about 30 minutes to an hour) to ensure that the hose is able to withstand long-term operating pressure. This is the ultimate guarantee of a safe and reliable hydraulic system.

Troubleshooting Common Problems

Even with the best preparation and execution, problems can occur. Knowing how to troubleshoot common problems can save time and money and potentially prevent dangerous situations from occurring. Let’s dive into some of the most common problems you may encounter.

Incomplete crimp

Symptom: The hose slips out of the fitting, or you notice a visible gap in the crimp.

Solution: Recalibrate the crimper and double-check the die size. Make sure you are using the correct pressure to complete the crimp.


Symptom: Hose and coupling are not perfectly aligned, resulting in an uneven crimp.

Solution: Re-align the hose and fitting to ensure they are perfectly parallel before crimping. If necessary, use a cork mallet to gently tap the fitting into the correct position.


Symptom: Fluid leaks at connection points can lead to reduced system efficiency and potential failure.

Solution: Double-check the compatibility of fittings and hoses. Make sure crimp pressure is within specified limits. If leaks persist, consider replacing hoses or fittings.

How to Attach Hydraulic Hose Fittings: A Comprehensive Guide

Welcome to a comprehensive guide to hydraulic hose fittings, tailored specifically for professionals in the hydraulic industry. From understanding the different types of fittings to the importance of proper installation, this guide covers it all. We’ll walk you through the selection process, the tools you’ll need, and step-by-step installation procedures. This guide also includes safety precautions and cost-effective tips to ensure you get the most from your hydraulic system.

Section 1: Types of Hydraulic Hose Fittings

JIC (Joint Industry Committee) Fittings

JIC fittings are versatile and commonly used. They have a 37-degree flare at the end and are great for high-pressure applications. They’re straightforward to install and provide a reliable seal.

ORFS (O-Ring Face Seal) Fittings

ORFS fittings come with an O-ring and a flat face. They are excellent for preventing leaks, especially in high-vibration systems. These are often found in modern hydraulic systems due to their efficiency.

NPT (National Tapered Pipe) Fittings

NPT fittings have tapered threads that form a tight seal when torqued. They’re a staple in the U.S. but be cautious; they can be prone to over-tightening, leading to thread damage.

BSP (British Standard Pipe) Fittings

BSP fittings are popular internationally and come in two types: parallel (BSPP) and tapered (BSPT). They’re reliable but not as common in the U.S., so you might need an adapter to use them.

Flange Fittings

These are used for connecting larger hoses or for high-pressure applications. Flange fittings are bolted together and offer a sturdy, leak-proof connection.

Section 2: Selecting the Right Hydraulic Hose

Pressure Requirements

First off, you need to know the maximum operating pressure of your hydraulic system. Always choose a hose with a pressure rating higher than your system’s max to provide a safety margin. This ensures that the hose can handle occasional pressure spikes without failing.

Material Composition

Next, consider the material. Rubber hoses are versatile and durable, but they can be heavy. Thermoplastic hoses are lighter but may not be as resistant to high temperatures or certain chemicals. Your choice will depend on the specific needs of your application, including the type of hydraulic fluid you’ll be using.

Wrenches and Spanners

First on the list are wrenches and spanners. These are your go-to tools for tightening and loosening fittings. Make sure you have a set that fits the sizes you’ll be working with. The right tool ensures a secure fit without damaging the components.

O-Rings and Seals

Next up are O-rings and seals. These small but vital components ensure a leak-free connection. Always have a variety on hand, as using the wrong size can lead to leaks or system failure.


Threadlocker is another must-have. This adhesive prevents loosening due to vibration or pressure changes. A small amount applied to the threads before tightening can make a world of difference in system reliability.

Safety Equipment (Gloves, Goggles)

Last but not least, don’t forget safety equipment like gloves and goggles. Hydraulic systems operate under high pressure, and a burst hose or leaking fitting can be dangerous. Always prioritize your safety.

Section 4: Pre-Installation Inspection

check hydraulic hose sizes Topa

Checking hoses and Fittings

Begin with a thorough visual inspection of hoses and couplings. Look for signs of wear, such as cracks, bubbles or leaks. If you notice any of these red flags, replace the parts immediately.

When inspecting, don’t just make a cursory glance. Use a flashlight to inspect the inside of the hose and the threads of the fittings. Sometimes wear is not immediately visible to the naked eye. Tiny cracks or slight distortions can be a precursor to more serious problems.

Run your hand along the hose to see if there are any inconsistencies. A hardened or brittle hose is a sign of aging and needs to be replaced. Conversely, a hose that feels unusually soft may have internal damage.

Pay special attention to metal fittings. Corrosion weakens metal, making it prone to breaking under pressure. If you notice any rust or discoloration, it’s time to replace them.

Verify Hose and Fitting Compatibility

Next, make sure the hoses and fittings are compatible. This may sound like a no-brainer, but mismatched parts can lead to leaks and even system failure. Be sure to double-check the specifications to make sure they meet your system requirements.

You should have the specifications for all fittings before you even consider connecting a hose to a fitting. This includes diameter, pressure rating, and material compatibility. If any of these don’t match, it could lead to poor performance or even catastrophic failure.

You can refer to the manufacturer’s guides for hoses and fittings. These guides provide valuable information about which products can be used in pairs.

If possible, pressure test new hose and fitting combinations before incorporating them into your system. This will test whether they are compatible and will meet the requirements of the system.

Sometimes, you may find that hoses and fittings are almost, but not quite, compatible. This is where adapters come in handy. However, use adapters sparingly and only as a last resort, as each additional component introduces another potential point of failure.

Keep it clean

Any dirt or debris can contaminate the hydraulic fluid and affect system performance. Before installation, clean all components and surrounding areas.

Contaminated hydraulic fluid can cause a number of problems, including reduced system efficiency, increased component wear and even system failure. Over time, even small amounts of dirt can cause significant damage.

Clean components with a lint-free cloth, special cleaning solution, or compressed air. Avoid materials that leave fibers or residue that can enter the hydraulic system and cause problems.

It’s not just the components that need to be cleaned; your work environment should also be free of dust and debris. A clean workspace minimizes the risk of contaminants entering the system during installation.

Once the installation is complete, you can flush the system to remove any potential contaminants that may have gotten in during the installation.

Section 5: Step-by-Step Installation

Shut down and depressurize the hydraulic system

Always shut down and depressurize the hydraulic system before touching the wrench. This is a safety step that should not be overlooked and will protect you from high pressure hydraulic fluid.

Shutting down and depressurizing the system is not just a recommendation, it is a requirement for safe operation. Hydraulic systems operate at extremely high pressures, and failure to depressurize can result in dangerous fluid injection or component failure, putting you at risk of serious injury.

Effectively stop the system by first turning off power to the hydraulic pump. Wait for all moving parts to come to a complete stop. Then only proceed to the next step.

Locate the system’s pressure relief valve and carefully open it to relieve built-up pressure. Always wear safety equipment such as gloves and goggles during this process. Monitor the system’s pressure gauge to confirm that the pressure has dropped to a safe level.

Once you believe the system has depressurized, double check by slightly loosening one of the low-pressure fittings to verify there is no residual pressure. Retighten the fitting before continuing.

Never skip or rush through this step. Taking a few extra minutes to make sure your system is safe can prevent accidents and save lives.

Cleaning Hose Ends and Fittings

Once the system is safe to work with, begin cleaning the hose ends and fittings. Use a lint-free cloth or compressed air to remove any dirt or debris. This will ensure a clean and safe connection. Lint-free cloths are effective for cleaning surfaces, and compressed air can be used in hard-to-reach areas.

Before you start cleaning, inspect the hose ends and couplings for any visible signs of wear or damage. If any parts are damaged, replace them before continuing.

After cleaning, perform another quick inspection of the components to ensure that all contaminants have been removed.

Apply Threadlocker (if applicable)

Apply a small amount of thread locker to the threads if the fitting requires it. This adhesive prevents the fitting from loosening due to vibration or pressure changes, thus increasing the reliability of the system.

Threadlocker is an extra layer of security for hydraulic systems. It fills in the gaps between threads, creating a bond that resists loosening forces such as vibration and thermal expansion. This is especially useful in high-pressure or high-vibration environments.

Applying thread locker is very simple. Clean the threads thoroughly and apply a small amount of adhesive. Don’t overdo it, apply a small amount several times. Tighten the fitting in place and allow the thread locker to cure before pressurizing the system.

Insert the fitting into the hose

Now, insert the fitting into the hose. Make sure it is inserted straight and secure. Any misalignment can lead to leakage, or worse, a burst hose.

Before inserting fittings, make sure that both the hose and fittings are clean and free of any debris. This will help achieve a tight fit.

When inserting the fitting, apply even pressure and make sure to insert it straight. Using a twisting motion can help to install the fitting correctly. Avoid excessive force, as this can damage the hose or fitting.

Some fittings may require specialized insertion tools. Always use the correct tool to ensure safe and proper insertion of the fitting.

After inserting the fitting, give it a gentle tug to ensure safety. Also, visually inspect the assembly to ensure that the fitting is fully seated and properly aligned.

Tighten the fittings

Grab a wrench and spanner and tighten these fittings. Tightening pipe fittings is a balancing act that requires both skill and attention to detail. Too loose and there is a risk of leakage or even disconnection under pressure. Too tight and you risk damaging the threads or even cracking the fitting. Some specialized fittings may require a torque wrench to ensure the correct force is applied.

After tightening, it is a good idea to mark the fitting and hose with a paint pen or similar tool. This will make it easier to visually inspect in the future to ensure that the fitting has not loosened over time.


Finally, double-check your work. Make sure there are no leaks and that all parts are aligned. If everything is in order, you can re-pressurize and test the system.

This can be done using methods such as visual inspection, applying a leak detection fluid, or even using specialized equipment for more complex systems.

Once you are confident that everything is in order, slowly repressurize the system while continuously monitoring for any signs of leakage or misalignment. After re-pressurizing, allow the system to go through a full operating cycle to ensure that everything is in order. Pay close attention to pressure gauges and flow meters to confirm that the system is operating within the specified parameters.

Taking the time to double-check your work adds an extra layer of assurance to your installation. The final step is to confirm that you have done everything correctly to ensure the reliability and safety of your hydraulic system.

The hose fittings Topa

Section 1: Understanding Hydraulic Hose Fittings

In the world of hydraulics, hose fittings are more than just connectors; they are the backbone that holds the entire system together. It can be said that they play a pivotal role in determining system performance, service life, and safety.

● Basic Definition and Function

Hydraulic hose fittings are specialized connectors used to connect fluid ports in hydraulic systems. These fittings ensure that the fluid transfer path is safe and leak-free and therefore play a vital role in the overall functioning of the system. They come in a variety of shapes and sizes and are designed to meet the specific requirements of different hydraulic applications.

● Why Quality Matters

Quality is more than just a catchphrase, it is a key factor in the success or failure of a hydraulic system. High-quality fittings ensure optimum performance and minimize the risk of leakage or system failure. Conversely, substandard fittings can lead to operational failures, increased maintenance costs, and even catastrophic system failure. Therefore, understanding the types and materials of hydraulic hose fittings is not only desirable but critical.

Reusable fittings offer the advantage of flexibility. These fittings can be removed from the hose and reused, making them ideal for applications that require frequent replacement or adjustment, such as research labs or prototype testing. While reusable fittings offer flexibility, they may not have the same sealing integrity as crimp fittings, especially in high-pressure systems. Therefore, they are generally recommended for low to medium pressure applications.

● Push-lock fittings

Push-lock fittings are the most convenient option. Designed for quick, tool-free installation, these fittings lock into place with a simple push. They are commonly used in automotive systems, light machinery, and some household applications. Push-lock fittings offer unmatched convenience and speed but are best suited for low and medium-pressure applications. They have limitations in high-pressure and high-vibration environments, making them less suitable for use in demanding hydraulic systems.

Section 3: Different Threads of Hose Fittings

When it comes to hydraulic hose fittings, the thread type is often an overlooked yet critical factor. Different threads serve different purposes and applications, and choosing the wrong one can lead to system failures, leaks, and inefficiencies. Let’s break down some of the most common thread types you’ll encounter.

●  JIC (Joint Industry Council)


JIC threads are widely used in the United States and are known for their reliability in high-pressure applications. They feature a 37-degree flare seating surface and are commonly found in industrial and automotive applications.
