NORGREN Self-venting safety coupling plug hose barb Ø13mm 237131300

▪ Single shut off: The plug designed straight through, coupling shuts off immediately when connection is broken. The ideal solution for operating compressed air tools
▪ Self venting: The first stage closes the valve and allows the downstream pressure to vent whilst the coupling is still joined avoiding whiplash. Once the pressure is vented the second stage disconnection releases the plug from the socket
