Brown Viton Solid Rubber O Ring Gasket Cord
Fluorocarbon rubber has excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals. Low temperature resistance is normally not favorable and for static applications is limited to approximately –15°F (–26°C) although in certain situations it is suitable down to –40°F (–40°C). Under dynamic conditions, the lowest service temperature is between 5°F and 0°F (–15°C and –18°C). Gas permeability is very low and similar to that of butyl rubber. Special fluorocarbon compounds exhibit an improved resistance to acids, fuels, water and steam.
Good Chemical Resistance:
Mineral oil and grease, low swelling in ASTM oil No. 1, and IRM 902 and IRM 903 oils
Chlorinated hydrocarbons (trichlorethylene and carbon tetrachloride)
Aliphatic hydrocarbons (fuel, butane, propane, natural gas)
Non-flammable hydraulic fuels in the group HFD
Very good ozone, weather and aging resistance.
Aromatic hydrocarbons (benzene, toluene)
Mineral and vegetable oil and grease
Fuels, also fuels with methanol content
Silicone oil and grease
Chlorine, Wet
High vacuum
Diesel Fuel
Gasoline
Not Compatible With:
Low molecular organic acids (formic and acetic acids)
Ammonia gas, amines, alkalis
Methyl Ethyl Ketone (MEK)
Glycol based brake fluids
Superheated steam
Brake Fluid
Acetone
