Abstract

The present invention relates to improvements in pipe fittings and in particular to fittings for high pressure fluid pipes, the said fittings of the crimping ring type comprising a rigid body provided with a bore and, at one of its ends, a threaded outer part on which is screwed a rigid nut. The part 3 forming a tight seal cooperates with the gripping part 4 which has several functions: the thin lip 4a is pushed by the seal and comes into close contact with the pipe 5 thereby producing a perfect seal anti-extrusion means, and the conical part 4d locked by tightening determines on the conical part 1d of the body a second perfect seal anti-extrusion means, the face 4e being in resting contact on the face 1b of the body and limiting the tightening of the seal; the rear part of the ring 4 produces the direct clamping of the pipe. The invention finds an application to ensure the reliable tightness of high pressure pipes.
