Abstract: A connector assembly includes a connector having an inner member with first and second open ends and a bore extending therebetween. The inner member is formed of a material which is impervious to a particular fluid to flow through the connector assembly. An outer member encapsulates the inner member and is formed of a material dissimilar from the material of the inner member, which material resists abrasions and other deleterious elements to which the connector is exposed. Flexible retaining latches are formed integrally on the outer member of the connector and snap over an annular projection formed on a tubular conduit upon insertion of the conduit through the first open end and into the bore of the inner member. An elastomeric seal disposed in the bore of the inner member provides a fluid tight seal between the conduit and inner member. Another elastomeric seal is located within the bore of the inner member adjacent the second open end, and provides a fluid tight seal with a tubular member inserted therein.

Abstract: FIG. 2A shows an alignment and sealing arrangement for connecting two non-gender opposed conduit parts (20) and (20'). Seal (22) is captured by two opposed seal protrusions (20C) and (20C') residing on conduit part's end. Bore (18A) of alignment element (18) closely receives opposed alignment protrusions located on conduit parts' end. The alignment protrusions are substantially referenced to their respective passageways. Axial force is applied to displace opposed conduit parts toward one another to cause seal protrusions to compress seal, drawing conduit parts' passageways (20E) and (20E') into an aligned relation, and reducing adjacent mating faces into approximate flush relation with one intersection (30). This coupling has one seal removed from direct contact with media, eliminates any appreciable media entrapment space, and desirably reduces flow disturbance along passageways of conduits.

Abstract: The present invention is a high pressure quick connector especially for use in connecting brake lines of a vehicle. The connector includes a housing which selectively receives a tube retainer cap. Retaining means such as a garter spring or snap ring allow for a low force insertion of the cap into the housing with an very high pull-off force.
