Comprehensive Analysis of Pneumatic Push in Fittings

Introduce

Pneumatic push in fitting is one of the commonly used pneumatic fittings in pneumatic systems, also known as quick connect or push in fittings, aimed at achieving fast and high sealing between pipelines and pneumatic equipment. Quick and convenient use is also a major breakthrough in pipeline connection technology. These innovative connectors have provided tremendous convenience for industrial manufacturing and pipeline connections today.

Understand pneumatic push in fitting

Simply insert the trachea into the connector and it will automatically lock without the need for tools. Pneumatic push in fitting is a quick connect component designed specifically for pneumatic systems, used to reliably and quickly connect air tubes with various pneumatic components such as cylinders, solenoid valves, distributors, etc.

Working principle

Pneumatic push in fitting has an extremely fast connection speed that can be directly inserted and unplugged, saving time. The principle behind this is as follows：

When the trachea is inserted into the pneumatic push in fitting, there is a metal or plastic snap ring called a collet inside the fitting. When the trachea is inserted, the gripper automatically opens; After the tube is fully inserted, the clamp immediately returns to its original position and clamps the outer wall of the trachea to prevent detachment. This stage is called Collet Grip

How is the sealing of such a simple intubation? There is an O-ring embedded inside the joint, which fits tightly with the outer diameter of the trachea when it is inserted to the bottom, forming a seal. This sealing ring can not only withstand the working pressure of the pneumatic system but also prevent air leakage and loosening. This stage is called O-ring Seal

When you want to pull out the trachea, simply press the release ring on the outside of the connector so that the claw will automatically release and the trachea can be easily pulled out. This stage is called Release Sleeve

Overall, the process of inserting and removing the trachea connector is relatively simple, without the need for additional tools, and can be carried out safely and efficiently.

The mechanism behind the connection

The working principle of Push-in Fitting is derived from its unique design structure, where each joint consists of several key components:

Body: It is the main structure of the joint, usually composed of materials such as plastic, stainless steel, and brass, used for different types of pipelines.

O-ring: It is a structure that maintains the sealing between the pipe and the joint, ensuring that no air escapes. Because it comes into contact with different gases, the material has characteristics such as being difficult to degrade and corrode.

Clamping mechanism: It is to fix the tube inserted into the joint to prevent it from being pulled out, usually a clamp with stainless steel teeth inside the joint.

Release mechanism: Simply push the release ring to easily pull the pipeline out of the structure.

Compared to the advantages of traditional connectors

Pneumatic push in fittings have many advantages over traditional structural joints:

Compared to traditional connectors, pneumatic push-in fittings can achieve advantages such as easier installation, flexibility, reusability, and time-saving.

Types of pneumatic push-in fitting

Pneumatic push-in fittings are available in various designs, materials, and shapes from Fokcaflow due to their different media and application industries. Each type has specific purposes and conditions, and understanding these differences is crucial for your rational selection and use.

Material

Plastic: Considering that this type of joint is used in industries with specific requirements for joint quality and corrosion resistance, it is usually made of nylon and POM materials.

Stainless steel: This material is generally used in pneumatic systems, maintaining strength and corrosion resistance while also having good cost-effectiveness.

Brass: Suitable for harsh environmental conditions, including video, marine, medical and other fields, it has excellent corrosion resistance, high temperature resistance and strength.

Shape

Straight type: connecting two pipes into a straight line

Bend type: Change the direction of the pipeline, the most common being 90 degrees, to flexibly design and avoid obstacles in the system.

Three way type: It is a common type of branch system, which can divide a single flow pipeline into two, or merge two pipelines into one, which is very practical in distributed systems.
