ABSTRACT:
A gasket having two opposed faces and an edge disposed therebetween is given a wide coating on the edge. The coating is sufficiently wide so that it goes from corner to corner on the edge and protrudes past the corner on at least one side of the gasket in a direction perpendicular to a facial plane of the gasket. The coating protrudes in an amount effective to give the gasket a sealing ability which is better than the sealing ability of the same gasket if it had a coating merely extending from corner to corner without protruding.
