High Temperature Gasketing
Carbon Fibers with a Nitrile Binder


  • Heat and Oxidation Resistant

    • Carbon fiber gasketing excels in harshest conditions- intense heat, high pressure, saturated steam* and hot oils
    • Laboratory tested for fire safety

  • Long-Lasting Seal

    • Unique manufacturing process minimizes cold flow and creep relaxation problems
  • Versatile

    • 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


  • Saturated steam*
  • Water
  • Oils
  • gasoline
  • aliphatic hydrocarbons
  • most refrigerants

+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.
