A pipe coupling is disclosed comprising a body (20) providing a tubular conduit enabling fluid flow therethrough from one end to the other. Each end is provided with an inner tubular portion into which a pipe end (10, 12) may be inserted. The body (20) has external threading and an outer tubular portion having a diameter larger than the inner tubular portion wherein an annular surface transiting between said inner and outer tubular portions is provided. A gasket ring (40) having a diameter suitable to fit around the pipe end (10, 12) is provided seated at the annular surface. A clinching sleeve (60) is further provided comprising a ring portion at one end having a diameter disposable within the outer tubular portion of the body (20) and providing an abutment surface against the gasket ring (40) upon being seated. A plurality of clinching flaps extends from the other end of the ring portion wherein each of the clinching flaps' inner surface is provided with gripping means and distributed to encircle a pipe end (10, 12). A coupling nut (80) is also provided having an inner opening at one end provided with internal threading complementary to said body's external threading, and an outer opening at the other end sufficient for the pipe end to be inserted therethrough. |
