Push Locks Features

push locks types

Construction

Barb or Insert

One or more serrated protrusions (or “Barb”) are located at the end of the Push lock fitting. This design ensures that the pipe is securely fastened to the fitting during installation. When the hose is pushed into the fitting, these protrusions are embedded in the inner wall of the hose, creating a tight, stable connection. This design prevents the loosening of the connection or air leakage.

Locking Mechanism

Some push lock fittings include an external locking ring or clamp to further ensure a tight connection between the hose and fitting. This mechanism prevents the hose from becoming disconnected due to pressure changes or external forces, ensuring long-term stability.

Seal

In some push lock fittings, O-rings or other forms of seals may be used to provide additional protection against leakage, especially in hydraulic or pneumatic systems, to ensure that there is no media leakage.

Working Principle

Simple Installation Process:

During installation, the user simply pushes the hose onto the fitting. As the hose is inserted into the fitting, it slides over the barb or insert portion of the fitting. These barbs are designed to grip the inner walls of the hose securely. This push-to-lock mechanism forms an immediate and tight connection without the need for any additional tools or complex assembly. The connection is completed simply by pushing the hose onto the fitting until it is fully seated, making the entire process incredibly quick and efficient.

Locking Mechanism:

Once the hose is inserted, the internal barbs (or insert) effectively lock the hose in place. The barbs create a strong mechanical hold on the hose’s inner surface, ensuring that the hose cannot be easily pulled off under normal operational pressures. This tight fit is what prevents leaks and guarantees a secure, stable connection, even when subjected to high fluid pressures.

No Extra Tools Required:

A major benefit of push lock fittings is that they do not require special tools for installation. The user can perform the assembly by hand or with simple mechanical aids, reducing the need for costly or time-consuming labor. This not only saves time but also minimizes the risk of damage during the installation process.

push lock fitting materials

Materials

Brass

Brass is a common material for push lock fittings and is used in a variety of environments due to its excellent resistance to corrosion, high temperatures, and good machinability. Brass fittings are commonly used in hydraulic systems, pneumatic systems, and low to medium-pressure applications.

Stainless Steel

Stainless steel offers very high corrosion resistance, especially for high-pressure environments and severe weather conditions. It can withstand high temperatures, acids, and alkalis, and maintains excellent mechanical strength over long periods of time. It is used in food, chemical,l, and other industries where high strength and corrosion resistance are required.

Aluminum

Aluminum is suitable for low to medium-pressure systems due to its lightweight, corrosion resistance, and good thermal conductivity. It is commonly used in aerospace, automotive, and other applications where weight is critical.

Advantages of Push Lock Fitting

Push lock fittings offer several significant benefits that make them an attractive choice for a variety of applications, from hydraulic and pneumatic systems to automotive and industrial machinery.

 

Easy and Quick Installation

One of the primary benefits of push lock hose fittings is their quick and easy installation process. Unlike traditional fittings that require special tools or complex procedures, push locks allow you to secure the hose and fitting with a simple push.

Secure and Reliable Connection

Push lock hose fittings create a tight, leak-proof seal between the hose and fitting, reducing the risk of leaks and failures. The barb design grips the inner surface of the hose tightly, ensuring a secure connection that can withstand high pressures and heavy use.

Versatility Across Multiple Applications

Push locks are highly versatile and can be used in a wide range of industries and applications. Whether you need a fitting for hydraulic systems, pneumatic applications, fuel lines, or even agricultural machinery, push lock hose fittings offer reliable and easy-to-use solutions.

Cost-Effective Solution

Because of their simplicity and ease of use, push lock fittings are often more affordable than other types of fittings that require more complex installation methods. Additionally, the reduction in installation time and the need for fewer tools and accessories helps lower overall project costs. This makes push lock fittings a cost-effective solution, especially for large-scale systems or projects on a budget.

Durability and Long-Lasting Performance

Push lock fittings are made from high-quality materials such as brass, stainless steel, and reinforced plastics, ensuring durability and resistance to wear, corrosion, and pressure. These materials are built to withstand demanding environments, whether you’re working in extreme temperatures, high-pressure systems, or corrosive atmospheres.

Compact and Lightweight Design

Push lock fittings are typically compact and lightweight, which is an advantage in space-constrained or weight-sensitive applications. Their small size allows for efficient routing of hoses and minimizes the impact on the overall design of a system or machine.

Installation of Push Lock Hose Fittings

The installation of Push Lock fittings is designed to be quick, simple, and tool-free, making them ideal for applications where time and ease of use are essential. Below is a step-by-step guide on how to install these fittings:

Step 1: Prepare the Hose

Ensure that the hose you are using is cut cleanly and evenly. A clean cut is essential for a proper seal and to avoid damage to both the hose and the fitting during installation. The hose must be the correct size for the Push Lock fitting to ensure a secure connection.

Step 2: Insert the Hose into the Fitting

Take the Push Lock fitting and insert the hose directly into the fitting’s barb or insert end. Depending on the design of the fitting, you may need to push the hose onto the fitting with firm pressure until the hose reaches the bottom of the fitting’s barb. The barb ensures the hose grips the fitting tightly.

Step 3: Lock the Hose in Place

Once the hose is fully inserted into the fitting, it will lock into place due to the barbed structure inside the fitting. The barb creates a tight connection between the hose and the fitting, preventing any slippage or leakage. In some cases, you may need to slide a hose clamp or locking ring over the fitting to ensure the connection remains secure.

Step 4: Check the Installation

After installing the fitting, inspect the connection to ensure that the hose is securely attached and that there are no visible gaps or misalignments. The fitting should sit flush against the hose, and the barb should be fully embedded in the hose material.

Step 5: Test the System

Once the fitting is securely installed, test the system by running the fluid or gas through the hose to check for any leaks. If there are any issues, disconnect the hose, check the fitting for damage, and reinstall it.

Avoid Common Pitfalls

When using push lock fittings, it’s crucial to be aware of common pitfalls that can lead to connection failures or performance issues. Here are some of the most important factors to keep in mind:

Material Compatibility

Using the wrong material for your push lock fittings can result in corrosion, weakening of the fitting, or failure to handle the system’s pressure or temperature requirements. For example, using plastic fittings in high-temperature environments or incompatible fluids can cause premature wear or leakage. Always ensure that the material of the fitting is suitable for the specific application, whether it’s brass, stainless steel, plastic, or aluminum.

Incorrect Hose End Size

Choosing the wrong hose size or push lock fitting diameter is one of the most common mistakes. If the hose end is too large or too small for the fitting, it will not form a secure connection, leading to potential leaks or hose slippage. Always verify the internal diameter of the hose and match it with the appropriate fitting size to ensure a proper seal and reliable performance.

Not Using the Proper Hose Clamp

While many push lock fittings can be installed without additional tools, some applications require the use of a hose clamp to prevent the hose from slipping off the fitting under pressure. Not using the correct size or type of clamp (or omitting it altogether) can lead to leaks, decreased system pressure, or even hose disconnection.

Incorrect Thread Type

Some push lock fittings feature threaded connections, and using the wrong thread type can cause leaks or failure to secure the fitting properly. BSP (British Standard Pipe) threads, NPT (National Pipe Thread) threads, and other common thread types may not be compatible with each other.
