ABSTRACT:
A gasket for use on a exhaust connection between an exhaust manifold and an exhaust pipe includes a spherical sealing portion which mates with sealing portions on both the exhaust manifold and the exhaust pipe. The spherical-to-spherical-to-spherical contact allows adjustment between the various sealing surfaces, while maintaining an adequate seal. Interference fits are utilized to secure the gasket to one of the exhaust manifold and exhaust pipe. Further, a method of forming the gasket involves first drawing a sheet into the general shape, and then punching all required openings in the gasket shape.
