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.
A fluid conduit coupling comprising; a tubular member defining a socket and having external threads, a tubular plug member slidably received in the socket for movement between a sealing position and a release position, the plug member including seal means for sealingly engaging the socket when in sealing position therein and for releasing the sealing engagement when in release position, a nut secured to the plug member and mounted for rotation in a fixed axial position on the plug member, the nut having a threaded portion engaging the tubular member for ...
