  • Single layer head gasket with integral stopper and method of making the same
    Patent number: 6209883
    Abstract: A gasket for use in an internal combustion engine is disclosed which includes a sealing element formed by an extrusion and ironing process in combination with a folding operation. The gasket has a plate that includes a body portion, a flange portion and an aperture. The thickness of the flange portion is reduced to less than that of the body portion by the extrusion and ironing process. The flange portion is then folded back onto a surface of the plate in facing relation to form a stopper seal to act as a primary seal. Optional embossments may then be formed radially and outwardly of the stopper seal so as to form a secondary seal.
