Abstract
A laminated expanded graphite gasket, such as an automotive head gasket, comprising a core and compressed expanded graphite facings and defining clear-through openings. A thin metallic layer is positioned on the graphite facing over less than 75% of the area of the facing for at least partial embeddment therein to enhance sealing stress in the covered portions, to improve impingment resistance of the gasket, and to improve other properties of expanded graphite gaskets.
