ABSTRACT:
A gasket having a gasket plate formed with an aperture. An annular flange provides a stopper seal around the aperture. The flange has spaced areas of varying thickness. The gasket is formed by punching an opening in the gasket plate inwardly of an annular array of bolt-holes. An annular portion of the plate surrounding the opening is folded back to form the flange and place it in surface-to-surface contact with the plate. The areas of the flange adjacent to the bolt-holes are compressed a greater amount than areas of the flange more remote from the bolt-holes.
