Inorganic fibers with a nitrile binder.

Features and Benefits

Heat and oxidation resistance

  • Inorganic, asbestos-free fibers offer superior performance in saturated* and superheated steam*
  • Thermally stable fibers retain effective seal even during thermal cycling to 750°F (400°C)

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.
