What is a quick coupler?
Quick coupler is a quick-disconnect fitting used in a hydraulic or pneumatic system to quickly connect lines without losing fluid or fluid pressure. They are designed to be connected and disconnected immediately without the use of tools, eliminating the need to close valves, bleed the system, recharge with fluid, and/or purge air from the system.
A quick coupling is a mechanical device that provides a fast, easy, sure way to repeatedly connect and disconnect almost any fluid or gas line. All quick-connect couplings have two parts: a plug and a socket. The plug is the male half and the socket is the female half.
