ABSTRACT:
A quick connect and disconnect coupling includes a connetor for housing a fluid conduit. The conduit includes a flexible tube terminating in an upset bead. One or more adjoining O-ring seals encircle the tube adjacent the upset bead. The connector includes a plug for receiving the tube. The plug terminates in an end wall adjacent the O-rings. A first chamfer is provided in the plug end wall. A second chamfer is provided in the upset bead adjacent the O-ring seals. During installation and removal of the connector, the O-rings are compressed and forced into the first and second chamfers to retain the O-rings in place on the tube.
