ABSTRACT:
A sealing gasket to be clamped in particular between pipe-coupling flanges comprises a sealing packing of expanded graphite placed between an inner reinforcement ring and an outer reinforcement ring, the two rings being placed at different levels prior to clamping. The graphite packing is applied against bearing surfaces formed and oriented on the reinforcement rings so that, at the time of clamping of the gasket, the resultants of the forces transmitted to the bearing surfaces are in the same direction and of opposite sense, thus inducing a compression of the sealing packing.
