Abstract: A gasket including an annular metal core and at least one radially outwardly projecting, compressible gasket ring made of a high-temperature resistant, expanded graphite material. The gasket ring is arranged on the metal core and, after mounting, is essentially aligned with the metal core. The metal core has a circular recess in a form of a V-shaped trough on an outer circumference thereof, into which recess the gasket ring is inserted. The gasket ring is made of a graphite material and has on at least two axially facing side edges adjacent the metal core an inclined slope of approximately 45.degree.. The metal core consists of a high strength metal alloy selected from the group consisting of 304L stainless steel, 316L stainless steel, 321 stainless steel, 329 stainless steel and inconel 600.

Abstract: The method comprises taking textile or synthetic threads and impregnating the threads by passage in a bath of an elastomer or plastomer material. Thereafter a band is formed from the impregnated threads and shaped into a ring and moulded under pressure.
