Seal for assembling fluid-circuit tubular elements

摘要

The invention relates to an annular seal used for the telescopic mounting of a male end (10) of a first tubular element ( 1 ) in a socket ( 20 ) of a second tubular element ( 2 ). Said seal comprises an elastically-deformable annular body ( 3 ) designed to be threaded around the outer surface of the male end (10) and an anchoring lug ( 4 ) that only extends over part of the length of the body projecting radially around the latter and designed to be housed in an anchoring groove ( 25 ) disposed in the inner surface of the socket. At least one part of the lug ( 4 ) is made from a reinforcing material having a hardness greater than that of the body ( 3 ). Said seal is characterised in that the reinforcing material is located radially at a distance from the inner surface ( 32 ) of the body ( 3 ). Use: water supply and disposal networks.
