ABSTRACT:
This invention relates generally to novel gaskets having continuous multiple seals created by utilizing a core of functionally corrugated material encapsulated by a graphite material such that an interactive relationship exists between the graphite, the functionally corrugated core, and the surfaces to be sealed. Specifically, the present invention relates to fail-safe, ring-type, concentrically corrugated, graphite encapsulated gaskets with continuous, multiple seals creating a multiplicity of parallel, fluid-locked, graphite-densified, barriers for use in the petrochemical industry to seal flange connections. The present invention also relates to fail-safe, concentrically corrugated, graphite encapsulated heat exchanger and internal combustion engine head gaskets with similarly created continuous, multiple seals. A method of manufacture of the gaskets is also disclosed.
