ABSTRACT:
A tube coupling having a throughway open at one end to receive a tube end, an annular groove encircling the throughway at a location spaced from said open end and an annular flexible sealing washer mounted in the groove and having an inner peripheral portion which projects through the open mouth of the groove to engage an outer surface of a tube which is a close fit in the throughway. The groove has one side nearest the open end of the throughway which lies in a plane generally transverse to the throughway to limit flexing of the inner part of the sealing washer towards the open end of the throughway and an opposite side of which is relieved at the mouth of the groove to allow the inner part of the sealing washer to take up a curvature in being deformed by forcing a tube through the washer. Thus the resulting stretching of the inner part of the washer by the tube provides a seal between the washer and tube and fluid pressure on the side of the sealing washer facing into the coupling body enhances the seal between the washer and tube.
