GRAPHONIC ®Metallic GasketThe superior technology of the GRAPHONIC ®family of gaskets ensures excellent sealing performanceand reliability, even in the most difficultapplications. Each of the three styles combines acorrugated metal core with a compressible sealingelement of various materials, for resistance to a widerange of harsh conditions, including extreme temperature,corrosive chemicals, and thermal cycling.GRAPHONIC ® GasketWith flexible graphite sealing element■■■■■Accommodates a wide range of temperaturesSeals effectively during thermal cyclingFire safe—withstood API and FITT fire testsChemically resistantLong service lifeTEPHONIC ® GasketWith ePTFE sealing element■■■■Chemically inertForms a tight seal under low bolt loadConforms to minor sealing surface imperfectionsWithstands temperatures to 500°F (260°C)G.E.T.
