ABSTRACT:
A quick-connect coupling is disclosed for manually joining together pipe or hose sections or the like. A pair of identical coupling bodies are provided, each containing an elastomeric annular face seal, and adapted for sealing engagement with a corresponding coupling body. Members are provided for releasably joining the coupling bodies together. The coupling forms a fluid-tight seal with its mate under low pressure conditions, yet when the coupling is over-pressured, it does not fail catastrophically.
