Inorganic Fiber Gasketing Material
Inorganic fibers with a EPDM binder



  • Tighter Seal
    • Inorganic fiber gasketing offers excellent thermal stability with minimal weight loss
    • Reduced creep relaxation and improved torque retention provide optimal sealability
  • Temperature resistant
    • Non-oxidizing fibers withstand a continuous operating temperature of up to 550°F (290°C), and maximum spike of 800°F (425°C)
    • IFG® 5500 has passed the Garlock Fire Test and is ABS Fire Safe Type Approved.




  • Water
  • Saturated steam*
  • Mild chemicals
  • Mild alkalies


*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 or superheated steam, consult Garlock Engineering.
