PRODUCT DESCRIPTION

Garlock Gaskets - Style 9850 - High Temp Compressed Graphite Gasketing
Benefits:
  • Heat & Pressure Resistant
    • Carbon fiber gasketing excels in harshest conditions - intense heat, high pressure, saturated steam† and hot oils (Style 9850)
    • Laboratory tested for fire safety
Tighter Seal:
  • Maintains effective seal during pressure and temperature fluctuations
    • Significantly reduces emissions to meet stringent Clean Air Act requirements
Convenient:
  • Flexible material is easy to handle and cut
  • Sheet sizes to 150" x 150" (3.8m x 3.8m) minimize waste and inventory costs
Media:
  • Saturated steam†, water, aliphatic hydrocarbons, oils, gasoline and most refrigerants

This is a general guide and should not be the sole means of selecting or rejecting this material. ASTM test results in accordance with ASTM F-104; properties based on 1/16" (1.6mm) sheet thickness.
* Values do not constitute specification limits All styles are furnished with an anti-stick parting agent as standard.

NOTES:
† For steam service above 150 psig, contact Engineering Refer to "Military Specifications" section under "Gasketing Terms" for order/ inquiry requirements. To ensure receipt of product with the required STR 508 approvals, certification will be required; associated fees based on quantity.

1 Based on ANSI RF flanges at our preferred torque. When approaching maximum pressure, continuous operating temperature, minimum temperature or 50% of maximum PxT, consult Garlock Engineering.
2 ASTM F37B Sealability
ASTM Fuel A (isooctane):
- Gasket load = 500 psi (3.5 N/mm2), Int. pressure = 9.8 psig (0.7 bar)
Nitrogen:
- Gasket load = 3,000 psi (20.7 N/mm2), Int. pressure = 30 psig (2 bar)
3 DIN 3535 Part 4 Gas Permeability, cc/min. (1/16" thick)
Nitrogen:
- Gasket load = 4,640 psi (32 N/mm2), Int. pressure = 580 psig (40 bar)
4 Saturated steam service guidelines:
> For optimal performance, use thinner gaskets when possible.
> Minimum recommended assembly stress = 4,800 psi.
> Preferred assembly stress = 6,000 psi to 10,000 psi.
> Retorque the bolts/studs prior to pressurizing the assembly.
> If the service is superheated steam, contact Applications Engineering.
