Ace Glass 7859-524 CHEMRAZ O-Ring, Size 115

CHEMRAZ White O-Rings

Molded of a perfluoroelastomer polymer, CHEMRAZ has the broadest chemical resistance of any elastomeric material. Combines the resilience and sealing force of an elastomer with chemical resistance approaching that of PTFE.

Features:

• Sealing Performance
  • Compared with other elastomers, CHEMRAZ is normally more resistant to swelling and embrittlement and will retain these properties for a longer period of time.
  • Compared with metal seals, CHEMRAZ is easily installed and conforms to the sealing surface despite irregularities due to improper assembly or wear.
  • Compared with PTFE seals, CHEMRAZ is not likely to creep or cold flow.
• Chemical Resistance - CHEMRAZ has excellent chemical resistance, far above that of other commercial elastomers. CHEMRAZ should be considered for service in hot, corrosive environments including:
  • Polar solvents (ketones, esters, ethers)
  • Strong organic solvents (benzene, dimethyl formamide, perchloroethylene, tetrahydrofuran (THF)
  • Inorganic and organic acids (hydrochloric, nitric, sulfuric, trichloroacetic) and bases (hot caustic soda)
  • Strong oxidizing agents (dinitrogen tetroxide, fuming nitric acid)
  • Metal halogen compounds (titanium tetra-chloride, diethylaluminum chloride)
  • Hot mercury/caustic soda
  • Chlorine, wet or dry
  • Inorganic salt solutions
  • Fuels, (ASTM Reference Fuel C, JP-5 Jet Fuel, aviation gas, kerosene)
  • Hydraulic fluids (SKYDROL1, 500A, PYDRAUL1 312, ANDEROL2 L-774, and transmission fluids)
  • Heat transfer fluids (DOWTHERM3A)
  • Oil well sour gas (methane, hydrogen sulfide/carbon dioxide/steam)
  • Steam
• Thermal Stability - CHEMRAZ O-Rings retain their elastic properties longer in harsh chemical environments at temperatures from -30°C to 220°C.
