ABSTRACT:
A quick connect tube coupling assembly includes a tubular seal member, in the form of a tubular member with an elastomer molded thereon is suitably fixed in the stepped socket bore of a tube receiving socket member, this seal member, in effect, providing the effect of two O-rings, a spacer, retainer and end seal; and a spring retainer is fixed to the socket member whereby this coupling body assembly is adapted to telescopically receive a plug tube having axially spaced apart radial upstanding annular inboard and outboard beads thereon, one of which is adapted to be engaged by the spring retainer. A tubular spring release member is positioned to encircle the tube loosely between the beads whereby the tube can be un-coupled, when desired, by moving this release member axially in a direction toward the inboard bead so as to cause the spring member to flux radially outward of the inboard bead whereby the plug tube can be removed manually from the socket member.
