Plastic push-in fittings, like stainless steel and aluminum quick release fittings, are plastic fittings with a plastic body. According to the actual needs, Ningbo Define develops and designs quick couplings for a variety of applications to solve the problem of sealing connections in many industries.

Ningbo Define does not choose stainless steel or aluminum alloy for the actual needs of the user, mainly because of the process requirements of the fittings, which do not allow scratches, etc.. This situation is often used in coated precision instruments, some automotive parts, plastic pipe fittings, Plastic push-in fittings body material or stainless steel to ensure the durability of the main body of the joint, while the front end jaws made of high-strength plastic. Through the improvement of the program, not only can the effect of efficient sealing connection and durability of the quick coupling, but also meet the process requirements of no scratches.

This type of method, which relies on replacing the front end jaws to meet the user's needs, is more practical, as the appropriate quick coupling is selected according to the specification of the tubing and then partially customized. However, some fittings can be directly corresponded with the standard product quick coupling type.

If there is no corresponding automated tooling and the number of products tested is small, then a manual solution can be used.

The manual solution for sealing connections of plastic pipe fittings is easy to operate and has a lightweight design. Its sealing principle is the same as that of pneumatic joints, which uses the sealing ring to form an extruded sealing surface on the pipe wall, and is suitable for sealing fittings made of stainless steel, aluminum, plastic, plastic hose, plastic steel and many other materials.

To sum up, Plastic push-in fittings are mainly designed for higher process requirements and to reduce pipe diameter scratches. It is not necessary that the entire part of the fitting is made of plastic, but can be modified according to the actual application needs. For better sealing performance of the connection and upgrade the specifications of the quick coupling to meet more market demand.
