What are Quick Coupling
Hydraulic quick couplings provide users with the ability to rapidly connect and disconnect hydraulic hoses to machines or other sections of plumbing. Also called quick-connects or quick disconnects, these fittings allow fluid to flow when the male and female sides are locked together. Conversely, when disconnected, the quick couplings prevent fluid leakage using check valves to block exiting fluid.
Quick connect couplers are manufactured by multiple manufacturers and can be often interchanged. Longwei supplies the highest quality hydraulic quick disconnect couplers such as flushface, ISO A, ISO B, wingnut, Ag, and Skid Steer.
