ABSTRACT:
A gasket (20) is provided for sealing a member with a rough micro-surface to a member with a smooth micro-surface. The gasket (20) has a layer (24) of graphite material and a layer (32) of an elastomeric or fibrous gasket material. An inner surface (28) of the graphite layer (24) is laminated to an inner surface (30) of the elastomeric or fibrous layer (32). When used for sealing, the graphite layer (24) is placed adjacent the member with the smooth micro-surface and the elastomeric or fibrous layer (32) is placed adjacent the rougher member. Alternatively, in addition to having a layer (32) bound to an inner surface of the graphite layer (24), a layer (38) of elastomeric or fibrous gasket material may be bound to the outer surface (26) of the graphite layer.
