Garlock High Temperature Style 9800 Gasket Material

Style 9800

High Temperature Gasketing
Carbon Fibers with a SBR Binder


Heat and pressure resistant

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

Tighter seal

  • Maintains effective seal during pressure and temperature fluctuations
  • Superior torque retention lowers leakage rates and reduces maintenance time


  • Flexible material is easy to handle and cut
  • Sheet sizes to 150″ x 150″ (3.8 m x 3.8 m) minimize waste and inventory costs


  • Saturated steam*
  • Water
  • Inert gases
  • Mild acids
  • 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 Hanna Rubber Company.
