Compressed Non-Asbestos Gasket Sheeting
Twelve compressed sheet styles from UL listed cellulose fiber to nuclear certifiable flexible graphite and fire safe carbon fiber, covering water, oil, steam, and severe high temperature flanges.
Anchor Seals Inc. can supply customized, pre-cut gaskets from any of the compressed non-asbestos sheeting materials listed below. The line runs from economical vegetable fiber sheet for water and oil joints, through all purpose aramid and inorganic fiber sheets for steam and hydrocarbons, to flexible graphite and carbon fiber sheets for the harshest thermal cycling and high pressure service.
See our specification table for compressed non-asbestos gasket sheeting for service applications, maximum and continuous temperatures, PSIG, and compressibility.
Twelve Compressed Styles
Why Compressed Non-Asbestos Sheet
Style 403 UL listed cellulose sheet and Style 408 rubber blended fiber sheet for economical water and oil joints.
Style 3760 builds gasket load on contact with oil or water and is twice as compressible as standard fiber sheet.
All purpose Styles 2900/3000, 3200/3400, and IFG-5500 for water, hydrocarbons, saturated steam, and inert gases.
Style 15 flexible graphite with 316SS foil, wire, or tang insert, nuclear certifiable, rated to 5000 psig.
Style 2000 woven graphite fills scratches, pores, and steam cuts to put worn flanges back in compliance.
HTC-9800, HTC-9850, and G-9900 carbon and graphite fiber sheets for saturated steam, hot oils, and fire safe service.
Twelve Sheet Styles by Service
Specification TableJump to a family below. Temperature, pressure, and compressibility for each style are on the specification table.
Cellulose and Vegetable Fiber Sheet
Economical general purpose sheet for water, oil, coolant, and salt solution joints.
403 Vegetable Fiber Water and Oil Sheet
Treated cellulose fiber material impregnated with a protein glue and glycerin binder. General purpose gasket material. UL listed.
408 Vegetable Fiber Sheet With Rubber
A blended rubber and cellulose fiber medium density beater addition material. Demonstrates good resistance to oils and water coolants and salt solutions.
3760 Water and Oil Sheet
Proprietary compound creates additional gasket load when the gasket comes in contact with oil or water. Twice as compressible as standard fiber gaskets. Conforms to irregular surfaces.
All Purpose Fiber Sheet
The workhorse compressed sheets for water, hydrocarbons, oils, gasoline, saturated steam, and inert gases.
2900/3000 All Purpose Sheet
General service for water, aliphatic hydrocarbons, oils, and gasoline.
3200/3400 All Purpose Sheet
General service for water along with saturated steam and inert gases. Style 3200 meets MIL-G-24696B.
IFG-5500 Inorganic Fiber All Purpose Sheet
General service inorganic fiber offers excellent thermal stability with minimum weight loss. Reduced creep relaxation and improved torque retention. Services water, aliphatic hydrocarbons, oils, gasoline, saturated steam, inert gases, and most refrigerants.
Flexible Graphite Sheet
Pure graphite sheet for critical and severe service, thermal cycling, and worn or damaged flanges.
15 Flexible Graphite Sheet
Flexible graphite provides excellent thermal stability along with oxidation and corrosion resistance. Very low creep relaxation and conforms to surface irregularities. Can be nuclear certifiable. Available with 316SS foil insert (Grade BSSC), 316SS wire insert (Grade BSC), or 316SS tang insert (Grade BTCSS).
2000 Woven Graphite Sheet
Woven compressed graphite foil for sealing new and worn flanges. Works for cryogenic services. Eliminates the spiral leak path associated with spiral wound gaskets and works exceptionally well in thermal cycling applications. Puts flanges back in compliance by filling in scratches, pores, and steam cuts with flexible graphite. Uses include manhole and hand-hole, diesel exhaust, turbine crossover, and heat exchanger applications.
Steam and High Temperature Sheet
Inorganic, carbon, and graphite fiber sheets for saturated and superheated steam, hot oils, and high pressure.
ST-706 Steam Sheet
Inorganic fibers offer superior performance in saturated and superheated steam. Minimizes cold flow and creep relaxation problems. In addition, services oils, grease, water, and heat transfer fluids.
HTC-9800 Carbon Fiber Hi-Temp Sheet
Carbon fiber excels in the harshest conditions, including heat, high pressure, saturated steam, and hot oils. Laboratory tested for fire safety. Superior torque retention lowers leakage rates.
HTC-9850 Carbon Fiber Hi-Temp Sheet
Carbon fiber excels in the harshest conditions, including heat, high pressure, saturated steam, and hot oils. Laboratory tested for fire safety. Superior torque retention lowers leakage rates. In addition, services aliphatic hydrocarbons, oils, gasoline, and most refrigerants.
G-9900 Graphite Fiber Hi-Temp Sheet
Graphite fiber withstands extreme temperatures and pressures and significantly reduces emissions. ABS fire safe type approved and maintains a superior seal during thermal cycling, even in saturated steam and hot oils. Services saturated steam, water, inert gases, aliphatic hydrocarbons, oils, gasoline, and most refrigerants.
Every style listed can be supplied as sheet or cut to customized, pre-cut gaskets. Confirm limits for your specific media, temperature, and flange with an Anchor Seals Inc. representative.
Frequently Asked Questions
All Gasket SheetingWhat is compressed non-asbestos gasket sheeting?
Compressed non-asbestos sheet is made from cellulose, aramid, inorganic, carbon, or graphite fibers bonded under heat and pressure with an elastomer or other binder. It replaced compressed asbestos sheet and is the standard material for flanged joints in water, steam, oil, fuel, and mild chemical service.
Which style should I start with for general service?
Styles 2900/3000 cover water, aliphatic hydrocarbons, oils, and gasoline. Styles 3200/3400 add saturated steam and inert gases, and Style 3200 meets MIL-G-24696B. Move to IFG-5500 when torque retention and thermal stability matter, and to ST-706 for superheated steam.
When do I need flexible graphite instead of fiber sheet?
Choose Style 15 or Style 2000 for thermal cycling, cryogenic service, high pressure, or flanges that are scratched, pitted, or steam cut. Graphite conforms to surface damage with very low creep relaxation, and Style 15 can be supplied nuclear certifiable with a stainless steel insert.
Which styles are fire safe?
HTC-9800 and HTC-9850 carbon fiber sheets are laboratory tested for fire safety, and G-9900 graphite fiber sheet is ABS fire safe type approved. All three hold torque and a tight seal in saturated steam and hot oils.
