Abstract: A fluid coupling includes a carrier carrying a retention ring with inward and outward radially and angularly extending fingers for respectively engaging an outer surface of an endform inserted through a bore in the carrier and the inner surface of a bore in a housing in which the carrier is mounted to fix the endform to the carrier and to fix the carrier to the housing. Inner and outer seal elements are also carried on the carrier to seal the carrier to the endform and the housing to the carrier. Both of the seal elements are disposed axially closer to one end of the carrier than the inward and outward extending fingers.

Abstract: A fluid quick connector is mountable onto the threads of a threaded fluid component in a sealed fluid connection. A retainer element carried by the fluid quick connector is engagable with the threads on the second fluid component. In one aspect, the retainer element is at least one tab projecting inward into a bore in the quick connector body for engagement with the threads on the fluid component. In another aspect, the retainer is a resilient member carried within an expanded chamber in the quick connector body which has resilient legs positioning a tip end into engagement with the threads on the fluid component.

Abstract: A fluid quick connector includes first and second rotatably, non-axially movably engaged housings. A retainer is mountable in the second housing for lockingly coupling a fluid operative element to the second housing. The first housing has an annular recess at one end which receives a collar extending axially from the second housing. Projections extend radially from the collar and engage the recess in the first housing to rotatably interconnect the first and second housings.

Abstract: A fluid quick connector adapted to be releasably mounted in a bore in a fluid use component. The quick connector includes a housing having a through bore releasably receiving a tubular endform. A retainer is mountable in the housing to latch the endform in the housing. A latch member carried on the housing is releasably engagable with a complementary latch receiver in the fluid use component. In one aspect, a latch member is carried on the end of at least one arm extending from the housing. Seal members are mountable in the bore in the fluid use component and retained in place by a top hat mountable in the quick connector housing. The top hat maintains the latch member in engagement with the latch receiver an the fluid use component.

Abstract: A quick connector includes a housing assembly for receiving one end of a conduit with an enlarged annular flange and a retainer for locking the conduit in the housing assembly. The housing assembly includes first and second housings which are rotatably and non-axially displaceably interconnected. A rigid top hat is fixedly mounted in the bore in the first housing to prevent axial displacement of the first and second housings. An annular recess in the top hat receives the flange on the conduit. The housings can also be incrementally indexable ribs on a stem of one housing fixedly and non-rotatingly engage an inner surface of a flexible conduit.

Abstract: A fluid connector includes at least one barb adjacent one end for expanding a flexible conduit thereover. At least one axially and radially extending, non-annular rib is carried on the connector adjacent to the barb. The rib alters the end shape of the flexible conduit into raised and lowered portions which resist rotation of the flexible conduit relative to the connector. The ribs may be employed on any fluid connector, including an adaptor between two fluid conduits, or on a one or two piece fluid quick connector coupling an end form to a flexible conduit.
