ABSTRACT:
A sealed joint between two members. The joint utilizes a gasket that includes a rigid plate having a generally U shaped corrugation therein that forms a recess in one face of the plate and a raised rib on the other face. The face having the raised rib has a layer of elastomeric material thereon on opposite sides of the rib for sealing engagement with one of the members. Elastomeric material is also contained within the recess for sealing engagement with the other member. One of the members may have a recess for receiving the gasket and the depth of the recess may be greater than the axial thickness of the rigid plate at the corrugation whereby the members do not impose axial compression on the corrugation when the joint is tight. In another form of the invention, the rigid plate may have another corrugation spaced from the first corrugation and of slightly greater axial length. This gasket may be used between two members, neither of which has a recess, and wherein the second corrugation is engaged by the members to limit the amount that the members may be brought toward each other and thus prevent the members from imposing axial compression on the first corrugation.
