ABSTRACT:
A quick connect coupling for tubing. The coupling includes a tubular male connector member adapted to be telescopically received within a tubular female connector member assembly. The female assembly includes a first member defining a seal bore and a cylindrical socket portion forwardly of the seal bore. A second female member includes a cylindrical portion which plugs into the socket of the first member and is held in position relative to the first member by sonic welding. A plurality of circumferentially spaced feet on the inner end of the second member are positioned proximate the seal to hold the seal in the seal bore and further engage the outer periphery of the pilot portion of the male member to minimize cocking of the male member relative to the female assembly. The second member also includes a plurality of circumferentially spaced resilient finger portions which snap into position in engagement with the rear annular face of the bead of the male member as the front annular face of the bead seats against the feet portions of the second member. The seal includes an annular main body portion, a plurality of axially spaced annular internal rib portions for sealing engagement with the pilot portion of the male member, and a plurality of axially spaced external rib portions providing an interference fit of the seal in the seal bore.
