ABSTRACT:
An improved fluid line connector in which an O ring seal (64) in a male portion (10) of the connector is better protected against failure in high-pressure or high-flow conditions. The seal is peripherally surrounded over more than half its thickness by a retainer (70) having an annular peripheral lip (72). In the sealed condition, reaction forces acting through the seal hold the lip (72) away from the valve seat structure while still permitting a perfect seal, and in the connected condition the retainer (70) provides maximum protection against washing out of the seal. In addition, a retainer securing ring (76) limits movement of the retainer (70) and further minimizes seal washout.
