Abstract
In a sealing gasket, multiple metallic gasket layers are interlocked together by cooperating self-aligning gripping members that mesh together. First and second gasket layers each have an engagement surface, a sealing surface and an aperture therethrough. Each engagement surface has disposed thereon a plurality of gripping members extending radially outwardly from a periphery of the apertures. The engagement surfaces of the first and second gasket layers are brought into face-to-face engagement such that the gripping members of the first gasket layer mesh together with the gripping members of the second layer to maintain the proper alignment of the first and second gasket layers and prevent lateral movement of the gasket layers with respect to one another.
