UNC vs UNF Fittings: What is the Difference?

Understanding the intricacies of Unified Fine Threads (UNF) and Unified Coarse Threads (UNC) is critical to the hydraulic fittings industry. UNF threads offer high tensile strength and excellent sealing capabilities, making them ideal for high-pressure and vibration-sensitive applications. On the other hand, UNC threads are easier to assemble and often more cost-effective, making them suitable for general-purpose and maintenance-intensive systems. If you would like more detailed information, please continue reading the article.

Understanding Thread Terminology

Before delving into the nuances of Unified Fine Threads (UNF) and Unified Coarse Threads (UNC), it is important to understand the basic thread terminology used to support hydraulic fittings. With this basic knowledge, you will be able to make more informed decisions and better understand the specific properties of UNF and UNC threads.

Pitch

The term “pitch” refers to the distance between corresponding points on adjacent threads, usually measured in millimeters or threads per inch (TPI). In hydraulic fittings, pitch plays a critical role in the gripping power of the threads and the likelihood of fluid leakage. The finer the pitch, the better the sealing performance, but the ease of assembly may be sacrificed.

Diameter

“Diameter” is another key metric and is generally categorized as large, small, and pitch diameters. The major diameter is the maximum diameter of the thread, and the minor diameter is the minimum diameter. The pitch diameter is in between and is the diameter where the opposing thread sides intersect. In hydraulic applications, understanding diameter is critical to ensure compatibility between threaded components and to minimize mechanical stress.

Thread Form

“Thread Form” describes the cross-sectional profile of a thread, including angle, depth, and width. For example, UNF and UNC threads follow a specific thread form, the Unified Thread Standard (UTS). The form of a thread affects its load-carrying capacity, durability, and suitability for specific hydraulic tasks. The selection of an inappropriate thread form can lead to inefficiencies and safety risks, so careful selection is required.

Lead

“lead” refers to the axial travel distance of a threaded part in a 360-degree rotation. In multi-start threads, this value is a multiple of the number of starts. In hydraulics, the lead determines the speed of assembly and disassembly, as well as the thread’s resistance to loosening under vibration stress.

What is a UNF Thread?

UNF threads are characterized by a fine pitch and a smaller helix angle. Essentially, a fine pitch means more threads per unit length than a thread with a coarser pitch. The fine pitch gives UNF threads excellent vibration resistance and high tensile strength. In terms of thread form, UNF conforms to the Unified Thread Standard (UTS) and is characterized by a side angle of 60 degrees.

Applications

UNF threads are typically used in applications requiring high precision and high load capacity. Due to their vibration resistance, UNF threads are often used in dynamic hydraulic systems such as mobile equipment and aviation hydraulics. In addition, their high tensile strength makes them suitable for high-pressure systems. Another common application is in miniature components where space is limited but performance cannot be compromised.

Advantages of UNF threads

High tensile strength: The fine pitch and robust thread form contribute to high tensile strength, making UNF threads popular for applications requiring ruggedness.

Vibration resistance: UNF threads offer better resistance to vibration loosening than coarser threads, which is very desirable in dynamic hydraulic systems.

Precision: Fine pitch allows for more precise adjustments, which is critical in applications where precise tolerances are required.

Excellent sealing capability: The design features of UNF threads contribute to excellent sealing, minimizing the chance of leakage in hydraulic systems.

Limitations of UNF threads

Complicated assembly: Due to their fine pitch, they must be assembled carefully to avoid the risk of cross-threading or over-tightening.

Cost: Higher manufacturing accuracy results in higher costs, an important consideration for applications with lower budgets.

Limited availability: Not all hydraulic components are available with UNF threads, sometimes they need to be used in conjunction with adapters or other components.

What is a UNC Thread?

UNC threads are characterized by a coarse pitch and are the most common threads for general-purpose fasteners.UNC threads are characterized by a low number of threads per unit length, which facilitates assembly and disassembly.UNC threads conform to the Unified Thread Standard (UTS), and have a 60-degree flank angle like their UNF counterparts.UNC threads have been developed to meet the requirements of the Unified Thread Standard (UTS) and have a 60-degree flank angle.

UNC hydraulic fittings chart

Applications

UNC threads are used in a wide range of applications where quick assembly and disassembly is required. This includes maintenance-intensive hydraulic systems and general-purpose applications in industrial machinery. Due to their design, UNC threads are often used in larger-sized hydraulic components. In addition, UNC threads are often used in systems where vibration is not a concern, but where assembly is simple.

Advantages of UNC Threads

Ease of assembly and disassembly: The thicker pitch simplifies assembly, making it faster and less likely to cross-thread.

Cost-effective: UNC threads are generally less expensive to manufacture than fine threads.

Availability: Because UNC threads are so widely used, they are readily available, which reduces lead time for parts procurement.

Versatility: UNC threads are versatile in both general and specialized hydraulic applications.

Limitations of UNC threads

Lower vibration resistance: A thicker pitch reduces vibration resistance, making UNC threads less suitable for dynamic hydraulic systems.

Poor sealing ability: Coarse threads may not seal as well as fine threads, increasing the potential for leaks in high-pressure systems.

Lower load capacity: While thicker threads are easier to assemble, they do not have the same load capacity as fine threads, which may limit their use in high-pressure environments.

UNF vs. UNC: the Main Differences

Pitch differences

The core difference between UNF and UNC threads is the pitch; UNF threads have a finer pitch and more threads per length. On the contrary, UNF threads have a coarser pitch and fewer threads per length. The implications are manifold: UNF threads typically have better sealing ability and higher tensile strength, while UNC threads make assembly and disassembly easier and faster.

Strength Considerations

Strength remains the primary consideration in hydraulic applications. UNF threads are ideal for high loads and high pressures because of their higher tensile strength due to the fine pitch, while UNC threads, while easier to assemble, typically have lower load-carrying capacity. Therefore, UNF threads are a more suitable choice for applications that require ruggedness and the ability to withstand extreme pressures.

Application-specific suitability

Dynamic systems: UNF threads are suitable for dynamic hydraulic systems, such as mobile equipment or aerospace systems, where vibration resistance is critical.

Heavy maintenance environments: UNC threads excel in systems that require frequent maintenance because they are easy to assemble and disassemble.

High-pressure systems: If the application involves high-pressure hydraulic systems, UNF threads are often preferred because of their excellent sealing capabilities and higher tensile strength.

General Industrial Use: UNC threads are more versatile and are often used in general industrial machinery where fine pitch threads offer no significant advantage.

Cost Sensitivity: For budget-conscious projects, UNC threads offer a more economical option due to their lower manufacturing cost, without significantly affecting performance.

Choosing the Right Thread

Understand the application: Before determining the thread type, it is important to fully understand the application of the hydraulic system. This includes the level of pressure the system will be subjected to, the type of fluid used, and the frequency of maintenance.

Review material compatibility: Threads can be made from a variety of materials. Make sure the material is compatible with hydraulic fluids to avoid corrosion or wear.

Refer to standards and regulations: Always check your selection against industry standards and local regulations to ensure you are in compliance.

Evaluate Life Cycle Costs: In addition to the initial purchase price, consider the long-term costs associated with maintenance, replacement, and potential system downtime.

Pilot test: Where possible, conduct a small-scale test to evaluate the thread’s performance under real-world conditions before full-scale implementation.

When to Choose UNF Threads

High-pressure environments: UNF threads are ideal for high-pressure applications due to better sealing and higher tensile strength.

Vibration Resistance: If the hydraulic system is subjected to high levels of vibration, UNF threads have a finer pitch, providing better locking and vibration resistance.

Longer service life: The higher cost of UNF threads can be justified in applications where long service life is required and frequent replacement is not possible.

Specialty applications: In aerospace, military or other specialty hydraulic applications, UNF threads are often preferred for their superior performance characteristics.

When to Choose UNC Threads

Ease of assembly: UNC threads are easier and faster to assemble and disassemble, making them ideal for systems that require frequent maintenance.

Lower initial cost: If budget constraints are an important consideration and the application does not involve high pressure or vibration, UNC threads are a more economical choice.

Versatility: For mechanical and hydraulic systems where a fine pitch does not provide substantial benefits, UNC threads offer versatility without sacrificing performance.

How to Identify UNF and UNC Threads

Visual Inspection

Thread count: Generally, UNF threads have more threads per inch than UNC threads. An initial visual inspection is sometimes sufficient to distinguish between the two.

Thread Profile: A closer look at the thread profile can also provide some clues; UNF threads have a narrower thread profile due to the finer pitch, while UNC threads appear thicker and wider.

Physical Measurements

Thread Pitch Gauge: One of the clearest methods is to use a thread pitch gauge. By placing the gauge on the thread, the correct pitch will fit perfectly.

Thread Counting: As an alternative, you can count the number of threads on a bolt or screw in one inch of length. A higher number of threads is usually referred to as UNF, while a lower number of threads is referred to as UNC.

Diameter Measurement: It is also possible to measure the diameter of a thread, but this alone may not be conclusive. In general, you can cross-reference the diameter with the number of threads for a more accurate identification.

Consult the documentation

Manufacturing specifications: Always refer to the product manual or technical data sheet that came with the hardware, which should specify the thread type.

Industry Standards: Thread standards (SAE, ASTM, etc.) often reveal the thread type. For example, SAE bolts with fine threads are typically UNF threads.

Manufacturer Markings

Some manufacturers stamp markings on the surface of bolts and screws, which can be decoded to determine the thread type. Although this method is not universal, it can quickly identify UNF and UNC threads.

Understanding the nuances of thread terminology, such as pitch, diameter and thread form, is critical to making an informed choice. These parameters affect everything from sealing ability and mechanical stress to assembly and disassembly speed. By carefully considering the unique requirements of your system, referencing industry standards, and even conducting pilot tests where possible, you can optimize the selection process to ensure the most efficient and cost-effective operation. Proper thread selection is the foundation of any hydraulic system’s long-term reliability and effectiveness.

Definition of Hydraulic Adapters

Definition of Hydraulic Adapters: The Ultimate Guide

In a hydraulic system, adapters are important components that connect the various hoses, tubes and pipes in the hydraulic system. They are critical to the smooth, efficient flow of hydraulic fluid and the overall performance of the system. Whether you’re a seasoned professional in the hydraulics industry or a zero-seller looking to break into the business, understanding the nuances of adapters can add tremendous value. This comprehensive guide will take you through everything you need to know about hydraulic adapter.

Definition of a Hydraulic Adapters

Adapters are specialized connectors that are used to seamlessly join various types of hoses, tubes and pipes in a hydraulic system. This type of connector plays a vital role in ensuring that the different components in the system can work together and facilitate the efficient flow of hydraulic fluids. The adapter acts as a bridge, both to allow fluid to flow between different components and to change the direction of fluid flow. It is an indispensable component that simplifies connections and improves the overall performance of a hydraulic system.

Components of Adapters

Main Body: It is the backbone for the adapter. The dimensions of standard adapters are fixed, but they can also be tailored to the components you want to connect. Whether you are connecting a hose to a tube or a tube to another tube, the shape of the main body adapts perfectly to these components.

Threads: The threads on the adapter are spiral ridges that, when twisted into place, ensure that the adapter locks securely in place. That way, it won’t wobble or pop off under pressure.

Sealing Surface: This is the safety guard of the adapter. It prevents leaks by forming a tight seal when you connect it to another component. The sealing surface is critical to maintaining a high-performance, leak-free system.

Hydraulic Adapter Types

Hydraulic systems are like jigsaw puzzles. Let’s say you have different hydraulic components that all need to fit together just right. But what happens when two parts don’t match? That’s where hydraulic adapter fittings come in. So let’s take a deeper look at the types of adapters and how they build high-performance hydraulic systems.

Couplings

First up is the coupling. Imagine there are two pipes, how do you connect them? The coupling is the answer. Couplings have female threads at both ends and can connect two identical male parts so that fluid can flow smoothly from one to the other. A coupling with different sizes at each end can be called a reduction coupling, which connects two fittings of different sizes. Standard couplings have stop zones inside, called internal stops, which prevent the pipe from being inserted too deeply and affecting the function of the connection.

Bushings

A bushing is similar to a close nipple fitting, but it has threads on both ends. Bushings have larger male threads and relatively small female threads. Let’s say you have a large opening but need to fit a smaller part into it. A bushing will help you with this.

Nipple

Sometimes you need to connect two fittings together. This is easily accomplished by using a fitting. It is a short piece with threads on both ends. By screwing one end into the first fitting and the other end into the second fitting, the fittings can be connected! If it has continuous uninterrupted threads, it is a close nipple.

Union

Now, what if you have different parts that may need to be taken apart later? The union is the perfect adapter for you. A union is similar to a coupler, but with differences. It allows you to connect different parts, but also allows for easy disassembly. So if you need to replace or maintain a part, you can easily remove it without disassembling the entire system.

Reducer

Reducing couplings have two ends: a larger one for larger pipes and a smaller one for smaller pipes. When these two ends are inserted into their respective pipes and tightened, hydraulic fluid can flow seamlessly between the two differently sized components.

Elbow adapters

Sometimes you need to change the direction of flow in your hydraulic system. Maybe you want to make a 90-degree or 45-degree bend. An elbow adapter can help you do just that. It allows you to change the direction of fluid flow, making your system more flexible. If the two ends of the fitting are different sizes, it is a reducer elbow fitting.

Tee Adapters

Tee adapters allow fluid flow to be split into two directions, or the two directions can be combined. Common tee ports have the same size threads, but of course, there are tees with different thread sizes. And the types of threaded ports of tees can also be different types.

Cross Adapters

Cross adapters are also called four-way fittings. That is, a cross fitting has four ports, each of which is threaded. Cross adapters allow fluid to be split into three different directions.

Material Selection

When it comes to adapters, materials are more than just a minor detail; they change the rules of hydraulic system use. The material you choose affects the longevity, rust resistance, and strength of your adapter.

Carbon Steel

Carbon steel is strong, which means it can withstand a lot of pressure. But beware of rust. Over time, carbon steel can corrode, especially when exposed to moisture.

Stainless Steel

Next up is stainless steel. This material is a champion of corrosion resistance. If you’re worried about rust, it’s your go-to choice. The downside is that it is more expensive than carbon steel.

Brass

Brass material is resistant to heat and corrosion. If you want both strength and rust resistance, brass is a good middle ground.

International Standards

Let’s talk about international standards for hydraulic fitting adapters. You may ask, what does this have to do with anything? These standards for hydraulic adapters are what various countries have developed to ensure that hydraulic systems function properly. Here, we will broadly analyze the three main standards: ISO, SAE, and EN standards.

ISO (International Organization for Standardization)

First of all, there is ISO, a standard that is important on a global scale. It sets high requirements for quality and safety. When you see “ISO certified” you know you have a quality product. The fittings will be rugged, durable and fit perfectly to keep your hydraulic system in top shape.

SAE (Society of Automotive Engineers)

The SAE standards come from the United States and are aimed at mobile machinery such as automobiles and tractors. If you work in the automotive field, SAE is your standard of choice. It ensures that your adapter is as rugged as your machine.

EN (European Standard)

Finally, there’s EN. It’s a European standard that focuses on consistency. en ensures that every adapter is built the same way every time. This means there is less chance of a fault that could damage the hydraulic system.

Connection Methods

When you’re setting up or maintaining a hydraulic system, different hydraulic equipment requires different kinds of connections, and how you connect adapters can make or break an operation. Let’s take an in-depth look at the main connection methods for hydraulic adapter and learn about their advantages and disadvantages.

Threaded Connections

Threaded connections are the most common type of connection. Common adapters are available with different types of threads, such as JIC, SAE, JIS, BSP, NPT, and ORFS. because the threaded connection is the most common connection, it is usually the most cost-effective and easy to install. Installation is simply a matter of screwing the adapter into place. But remember, torque is key. If it’s tightened too tightly or too loosely, it can lead to leaks. Therefore, it is important to torque it just right so that leak-free operation goes smoothly.

Compression Connections

Compression fittings consist of a fitting body, ferrule, and crimp nut, and include double and single ferrule fittings. Compression fittings are preferred for high-pressure applications. These fittings utilize force to hold the connection in place and are therefore very reliable under pressure. Therefore, if you work in an environment that involves the movement of high-pressure fluids, compression fittings are the best choice for you.

Push-to-connect

Push-in connections are the best choice for quick and easy assembly. You simply push the adapter into the receiving end and secure it with the appropriate clamp. However, they are not suitable for all situations, especially high pressures or temperatures. They are best suited for light to medium-duty applications.

Welded connections

Welded connections are the use of different solder to fix the adapter to the hydraulic application. They are permanent and therefore very robust and reliable. Once soldered, these adapters will not come off or move easily. What are the disadvantages of soldered connections? They are difficult to remove, so you want to make sure that the hydraulic system doesn’t need to be disassembled later.

Sealing Methods

You have found the right adapter and chosen the best connection method. The next thing to do is to understand the hydraulic fitting sealing method. A solid seal is the final step in ensuring a safe and efficient hydraulic system. Let’s take a look at the common sealing methods – O-rings, washers, and thread sealants.

O-Rings

First, there are O-rings. These round rubber seals fit snugly into grooves and prevent leaks. They come in a variety of materials such as NBR, EPDM, and PU. o-rings are inexpensive, easy to install, and work well under pressure. You’ll often find O-rings in high-pressure environments where a good seal is essential.

Gaskets

Next, let’s talk about washers. These flat seals sit between two surfaces and prevent fluid leakage. They come in various materials such as rubber, metal, or a mix of both, each with advantages and disadvantages. For example, metal washers are durable, but may not be the best choice for uneven surfaces. And some products are available in gasket sets. Therefore, you’ll want to choose a gasket based on your specific needs.

Thread Sealants

Thread sealant can be considered the “glue” of threaded connections. Apply it to the threads before screwing the components together. The sealant will fill the gap, making it difficult for liquid to escape. They are perfect for jobs that require a quick and secure seal. They make up for the lack of sealing in some threads, making them a relatively used hydraulic fitting sealant.

The Difference Between Hose Fittings and Adapters

When working with hydraulic systems, you will encounter various types of fittings. Two of the most common are hose fittings and adapters. While they may seem similar, they serve different purposes.

Hose Fittings

Simply put, hose couplings serve one purpose: to connect hoses. Whether it’s to extend the length of a hose or to connect a hose to a machine, these fittings are specialized for hose-to-hose or hose-to-machine connections. They are usually used for specific sizes and types of hoses and are therefore less flexible.

Adapters

On the other hand, adapters are the jack of all trades in the connector world. They can connect different types of components such as fitting to fitting, hose to tube or tube to tube. The design of adapters allows for more versatility, making them invaluable in complex hydraulic systems.

Dimensioning and Measurement

Sizing a hydraulic system is critical. Choosing the wrong fitting size can lead to a variety of problems ranging from small leaks to complete system failure. Let’s take an in-depth look at why accurate sizing is so important and how you can ensure proper sizing.

Selecting the Correct Size

Refer to the manufacturer’s guide: Always check the manufacturer’s specifications for each part first.

Understand system requirements: Different systems have different pressure and flow requirements. Make sure the dimensions meet these requirements.

Double-check measurements: It’s a good idea to double-check dimensions before finalizing an order.

Consult a professional: If you’re not sure, consult a professional or customer support. It’s better to take more time to confirm than to deal with the problem later.

Use calipers for accuracy: When measuring parts, using calipers can provide more accurate dimensions than a regular tape measure.

The material of the bead fitting is determined by the environment, and the common fitting materials are brass, stainless steel, and carbon steel. In order to ensure that the hose will not slip off, the size of the beaded hose fitting should be in line with the size of the hose.
