ABSTRACT:
A quick connect coupling is disclosed for use with a tubular conduit having a radially outwardly extending bead adjacent a free end of the tubing. The coupling includes an elongated tubular and cylindrical housing having an axial passageway formed through it which forms a fluid passageway and is open at both ends. One end of the housing has a enlarged diameter internal bore portion adapted to axially receive the free end of the conduit including the conduit bead as the conduit is inserted to a magnet position. A retainer within the internal bore portion of the housing lockingly engages the conduit bead when the conduit is moved to its connected position while fluid seals engage the outer periphery of the conduit. A one way valve is also contained within the housing passageway which permits fluid flow in only one direction through the housing passageway.
