ABSTRACT:
A gasket made of a plate having an annular central opening with an annular region concentric to the central opening, the annular region having a plurality of concentric deformable ridges and opposite facing grooves in a first and second surface of the plate. A sealing material comprising a plurality of expanded intercalated graphite worms overlies the annular region with the particles fixed to adjacent particles by compression. The ridges and the sealing material provide a plurality of seals having varying density and thickness that incrementally changes from a first edge of the sealing material to a second edge. The gasket is manufactured by compress the worms and the plate between dies to form the sealing material.
