Style 9900

High Temp Gasketing
Graphite fibers with a nitrile binder.


Heat and oxidation resistance
  • Graphite fiber gasketing withstands extreme temperatures and pressures, as well as many chemicals
  • Passed Garlock Fire tests, and is ABS Fire Safe Type Approved
Long-lasting seal
  • Unique manufacturing process minimizes cold flow and creep relaxation problems
  • Ideal for standard ANSI flanged connectors, as well as turbine crossover piping connectors
  • Multiple applications in power generation, chemical processing, hydrocarbon processing, and other industries


  • Steam*, oils, grease, water, heat transfer fluids+
+Contact Garlock Engineering with specific transfer fluid application.

*Minimum recommended assembly stress = 4,800psi.  Preferred assembly stress = 6,000-10,000psi.  Gasket thickness of 1/16" strongly preferred.  Retorque the bolts/studs prior to pressurizing the assembly.  For saturated steam above 150psig, consult Garlock Engineering.
