Abstract:
A metal static gasket for sealing axially flange facing surfaces when said metal static gasket is axially compressed between said flange facing surfaces, said gasket forming an annular body about an axis ZZâ€², the profile of the gasket in axial half-section being an elongated S-shape and comprising a lateral first portion which defines the inner peripheral surface of the gasket, a lateral second portion which defines the outer peripheral surface of the gasket, said lateral first and second portions being offset from each other in the axial direction of the gasket, and longitudinal third and fourth portions forming an arc, wherein the arcuated third portion has, at one of its ends, a first contract region that is substantially rectilinear and extends perpendicularly to the axis of the gasket and that is connected to one of the ends of the lateral second portion, and the arcuated fourth portion of has, at one of its ends, a second contact region that is substantially rectilinear and extends perpendicularly to the axis of the gasket, and that is connected to one of the ends of the lateral first portion so that the contact areas between said gasket and said flange facing surfaces occur only in said first and second substantially rectilinear contact regions, no contract occurring in said lateral first and second portions of said gasket.
