ABSTRACT:
An embossed gasket for providing a seal between a pair of confronting surfaces has at least one aperture and at least one embossment adjacent the aperture. The embossment defines a cavity, and a filler is disposed in the cavity. The filler prevents the embossment from flattening out when the gasket is compressed between two confronting surfaces, thereby concentrating the sealing effect of the embossment in the zone of the embossment and enhancing the sealing characteristics of the gasket.
