Abstract
The metal static gasket forms an annular body about an axis ZZ′. The profile of the gasket in axial half-section presents an elongated S-shape and comprises a lateral first portion defining the inner peripheral surface of the gasket, a lateral second portion defining the outer peripheral surface of the gasket, said lateral first and second portions being offset from each other along the direction of the axis of the gasket. The gasket also presents a curved third portion of undulating shape having a substantially rectilinear first contact region at one of its ends, and a curved fourth portion of undulating shape having a substantially rectilinear second contact region at one of its end extending perpendicularly to the axis of the gasket in such a manner that the gasket provides sealing between two flanges solely by means of the axial pressure exerted by the flanges.
