ABSTRACT:
A Hybrid Quick Connector for releasably interconnecting fluid carrying tubular members has a housing with first and second portions which are joined together to establish a through passage for fluid communication of the tubular members. One housing portion defines a first bearing surface and a retainer for releasably engaging an end form of one of the members. The other housing portion is permanently affixed to the end form of the other member and defines a second bearing surface which is axially spaced from the first bearing surface to straddle a resilient seal. Upon insertion of the first tubing end form, a retainer locks it in assembly with the quick connector and the seal acts to block the only potential leak path. Preferably, the first housing portion is formed of injection molded thermoplastic and the second housing portion is formed of mild steel to ensure a robust and inexpensive connector configuration which is particularly well suited for automotive air conditioning and engine coolant system applications.
