Abstract
A quick connector for connecting fluid lines includes a first connector having a housing for receiving a spool carrying conduit. The spool sealingly engages an endform on the conduit. At least one seal element and a retainer ring are pre-mounted in a bore in the housing and engage the spool to form a seal between the inner surface of the bore in the housing and the spool and to retain the spool in a fully inserted position in the housing. A method of assembling the quick connector is disclosed in which a stuffer pin is preassembled with the retainer ring mounted at a compressed diameter within a retaining collar on one end of the stuffer pin and the seal element mounted the stuffer pin. The stuffer pin is inserted into the bore in the housing until the seal element snaps into one groove in the bore and the retainer ring engages another groove in the bore in the housing. The stuffer pin is removed and a spool having a tapered end portion is slid through the retainer ring causing the tapered portion to expand the retaining ring outward until the retaining ring snaps behind an end shoulder on the spool. A centering collar carried on one of the spool engages an inner surface of the retaining ring to concentrically center the retaining ring with respect to a longitudinal axis through the tube and spool.
