hydraulic quick release coupling

Pneumatic and Hydraulic Quick Couplings

Features:
1) Uni-directional shut off coupler with an automatic shut off valve built in the
socket, recommended for piping of compressed air connections

2) Bi-directional shut off coupler with an automatic shut off valve built-in the
socket and plug, recommended for piping of chemicals, steam and oil

3) Double shut off couplings are used extensively when it is important to
minimize fluid loss upon disconnections

4) Both valves of coupler, the body and nipple, contain shut off valves, these
valves open automatically when the body and nipple are connected, and
close automatically when two valves are disconnected, keeping fluid loss
to the minimum
