Media
G-9900: Saturated steam, water, inert gases,
aliphatic hydrocarbons, oils, gasoline,
and most refrigerants
9800: Saturated steam †, water, and inert gases
9850: Water, saturated steam †, aliphatic hydro-
carbons, oils, gasoline, most refrigerants
At the Garlock on-site fire test facility, valves and
sealing materials have been tested for functionality in
the most extreme applications. G-9900, 9800, 9850,
ST-706 and IFG® 5500 meet these stringent fire test
standards.
Benefits
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 tempera-
ture fluctuations
■ Superior torque retention lowers leakage rates and
reduces maintenance time
Convenient
■ 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
