ABSTRACT:
A coupling for a fluid conduit under pressure has a plug carrying O-rings and inserted in a socket. A bead on the plug forms a stop for location of the O-rings. A nut rotatably mounted on the plug and held adjacent the bead has an elongated threaded annulus engaging threads on the socket so that nut rotation in either direction causes corresponding axial movement of the plug. Upon disconnection of the coupling the nut is partially backed off to remove the plug causing pressure release while the nut is still attached to the socket.
