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.

Profiles of male nipples help you to identify four popular styles of hydraulic quick disconnect couplers in nominal sizes ranging from 1/4" to 1". Nominal sizes represent intended hose or tube sizes, not the actual diameter of the coupler.
For actual dimensions, print this page actual size and compare the profile drawings to your existing equipment.
