<p>A spiral wound gasket having multiple windings of spirally wound strips of metal, fire resistant compressible filler material and oxidizer resistant compressible filler material is disclosed. The fire resistant filler material is arranged in a region toward the outside periphery of the gasket and the oxidizer resistant compressible material is arranged in a region radially closer to the inside periphery of the gasket. The gasket has excellent sealability characteristics from low to high gasket seating stresses, and is effective for use with corrosive chemicals while providing a measure of protection in fire situations.</p> |
