Abstract
A metal gasket has at least two metal layers having an aligned fluid-conveying opening. One of the metal layers includes a carrier layer and an active layer. The active layer has a raised metal sealing bead circumscribing the opening. The carrier layer and the active layer are at least partially coplanar and are spaced from one another within the plane by at least one cut-out region between the carrier layer and the active layer. The cut-out region allows the active layer to move out of the plane of the carrier layer, and thus, the active layer is able to self-adjust for sealing engagement between opposing surfaces in assembly and during use.
