Compatible Quick Couplings Manufacturer in China

Quick coupling is a very convenient coupling type because it is easy to install and also easy to disassemble. Quick couplings can be installed and released very quickly, so they are also called quick connect couplings, and quick couplings. They are usually used in industries such as agricultural machinery, chemical industry, and transportation.

Product List

In general applications, quick couplings are divided into ball valve quick couplings, poppet quick couplings, flat quick couplings, and a more special type of coupling: cam lock couplings. You can check the pictures below to choose the right product. If in doubt, please contact us.

What is a quick coupling?

Quick coupling is a type of coupling that can be quickly installed and disassembled. It is divided into two parts, male and female, and is widely appreciated for its simplicity of operation.

What are the advantages of quick couplings?

The most important advantage is that it is easy to install, saves time and effort, and has a wide range of use.

What is the structure of quick coupling?

Common ball quick couplings have plugs, balls and sockets.

What are the types of quick couplings?

Ball valve quick coupling, poppet valve quick coupling, flat quick coupling, cam lock coupling.

What are the materials of quick couplings?

Cast iron, brass, stainless steel, and steel are the most common materials used for quick couplings.

Where is the common environment for quick-connect fittings?

In those applications where it is necessary to enter and disassemble the fitting, quick couplings always overplay the most advantageous.
