Quick mount fitting

Claim 1

A fitting for outside diameter sealing of a smooth walled tube end, including: a body, a passage in said body, an entry for such smooth walled tube in said body, an inwardly continuous tapered area at said body entry, an annular elastomeric seaL with substantially spaced opposite circumferential tapered edges in the body passage, a split collet element between said annular elastomeric seal and said body entry continuous tapered area, said collet element having a plurality of arcuate cone sections which form a truncated cone at one end, a flange at the other end of the split collet element, and an intermediate continuous body wall of reduced diameter relative to the base of the truncated cone and the flange, said flange further having a taper complementary to the adjacent circumferential tapered edge of the elastomeric seal, said truncated cone, continuous body wall, and flange having a common passageway, the entire length whereof can contact the smooth wall of a tube inserted therein, a ram element in the body passageway positioned to one side of said elastomeric seal for contacting said seal, a passageway in said ram element leading to an open inner end of said ram element, a tapered edge at said inner end of the ram element which is complementary to the adjoining circumferential tapered edge of the elastomeric seal, and a member having a cam surface mounted to said body, said cam member movable to a first release position and to a second sealing position, whereby the cam surface translates said ram into sealing position by moving the ram tapered edge against the adjoining elastomeric seal edge to thereby move the split collet element so the truncated cone engages the body entry tapered area.
