ABSTRACT:
A gasket of the present invention is formed of at least one main plate having at least one opening to be sealed. At least one hard coating is formed around the opening of the main plate to have a predetermined lateral width. On an surface of the main plate with the hard coating, a soft coating is formed. The hard coating provides surface pressure when the gasket is tightened, and the soft coating tightly seals around the opening.
