Abstract: A composite gasket (1) arranged to be frictionally fitted around a rigid tube end (2) is designed for insertion into a part (3) provided with an aperture (4) in the form of a cylindrical bore for coupling with the tube end. The gasket includes at least one ring (5) made of an elastomeric material and at least one collar (6) made of a rigid material in the shape of a cylindrical sleeve parallel to and coaxial with the ring axis. The collar is adjacent to the ring and has an outer surface (9) suitable for mild frictional engagement with the inner surface (10) of the coupling aperture, while the shape of the ring-engaging end surface of the collar matches that of the ring.

Abstract: A device and a method for making a device for forming a leak-proof connection between a rigid tube end and the tip of a flexible pipe by crimping a metal sleeve portion onto the tip. The rigid tube end includes an end portion comprising a shoulder with a larger diameter than the tube. The device comprises a rigid insert having a cylindrical bore between both ends thereof and including on one side a tubular portion force-fitted into the tip of the pipe opposite the crimped part of the metal sleeve portion, and on the other side a portion provided with an outer flange having a matching shape and engaging the internal portion of the shoulder.
