Abstract
In a preferred embodiment, a compound gasket including a relatively nonresilient base member having an opening therethrough and a relatively resilient member disposed about the opening. The resilient member has a thickness somewhat greater than at least a portion of the base member so that mating surfaces between which the gasket is placed can be drawn together to contact the thickened portion of the base member so that the resilient member is compressed to a precise degree. The resilient member is freely movable with respect to the nonresilient member to better accommodate differential expansion and nonuniformities in the mating surfaces.
