ABSTRACT:
A coupling including a first sleeve having an exterior surface provided with an annular, frusto-conical surface and a second sleeve of larger diameter than the first sleeve and having an annular, interior frusto-conical surface, the second sleeve being disposed about the first sleeve. Interengaging elements align the frusto-conical surfaces to define a generally V-shaped annular, axially opening groove between the sleeves and an O-ring seal is disposed in such groove and abuts both the frusto-conical surfaces. A compressing ring engages the O-ring seal oppositely of the frusto-conical surfaces to drive the O-ring into sealing engagement therewith.
