ABSTRACT:
A connector for use with threaded and push-on outlet couplings of pressurized gas supplies, the former having an exteriorly threaded cylindrical pipe termination and the latter having a tapering pipe termination, the connector comprising: a resilient tubular member, having a flat annular flange at one end and a narrower middle section; and, a cylindrical cap member having a threaded bore for engaging a threaded outlet coupling, partially closed at one end by an annular shoulder for pressing the flange into a sealing position between the cap member and the threaded coupling, the annular shoulder defining a bore enabling the cap member to be slidably retained in the narrower section and having an inwardly directed circular edge which can press a portion of the narrower section into a sealing position between the cap member and a push-on coupling after the flanged end of the tubular member has been pushed thereover, whereby the connector may be used with both threaded and push-on couplings.
