Abstract
A static sealing element (1) includes an elastic tapered washer (10) the deformation of which enables a force to be transmitted, a casing (18) to establish the seal, and two supporting washers (27 and 28) which transmit the forces originating from the elastic washer (10) to the curved edges (20, 21) of the casing (18) so as to exert on them a pressure which maintains the seal. The casing (18) made thus be manufactured from a ductile material, but one which is less deformable than the customary elastomers.
