Abstract:
A unitary boundary gasket adapted for sealing between flanged portions of two axially mated surfaces of rigid metallic members, said flanged portions each containing a plurality of spaced bolt apertures; said gasket comprising:a) a one-piece radially outermost rigid metallic carrier having a first axial thickness, b) a one-piece radially innermost elastomeric sealing body bonded to said metallic carrier at the radially innermost edge of said carrier, c) said sealing body comprising a plurality of spaced apertures adapted for mating registration with apertures of said flanged portions, said apertures adapted for accommodating passage of bolt members for fastening said flanged portions together about said gasket, and d) said elastomeric sealing body further comprising a plurality of integrally formed waffle pattern regions extending longitudinally between said bolt apertures, each of said regions being presented only on one side of said gasket, each region being spaced away from any given bolt aperture, e) said elastomeric sealing body further comprising a plurality of segmented sealing beads extending longitudinally between each of said waffle pattern regions on said one side of said gasket, each of said segmented sealing beads being contiguous with the lateral boundaries of each of said regions.
