Flat gasket e.g. cylindrical head gasket, for internal combustion engine, has profile body exhibiting different material thicknesses when seen in radial direction and staying in effective contact with supporting bodies e.g. spacer rings

The gasket has a layer (1) provided with a passage (2) receiving an elastically deformable profile body (3) e.g. open or closed ring, that is formed as a circular profile wire. The profile body exhibits different material thicknesses when seen in a radial direction and stays in effective contact with supporting bodies e.g. U-shaped border (6) and spacer rings. The supporting bodies are connected with the layer. The profile body is partially enclosed in a region of its two front surfaces by the spacer rings, and the border encloses the profile body. Flachdichtung, insbesondere Zylinderkopfdichtung oder Auspuffflanschdichtung, beinhaltend mindestens eine mit mindestens einer Durchgangsöffnung versehene Lage, wobei die Durchgangsöffnung mindestens einen als ringförmigen Profildraht ausgebildeten, elastisch verformbaren Profilkörper aufnimmt, der, in radialer Richtung gesehen, unterschiedliche Materialdicken aufweist und der mit mindestens einem Stützkörper in Wirkverbindung steht.
