Chemical Resistant Fluorocarbon FKM O-Rings:

A chemical resistant Fluorocarbon FKM (Fluorocarbon Elastomer) compound 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. Under dynamic conditions, the lowest service temperature is between 5°F and 0°F. Gas permeability is very low and similar to that of butyl rubber.

Chemical Resistance:

  • Mineral oil and grease, low swelling in ASTM oil No. 1, and IRM 902 and IRM 903 oils
  • Hydraulic Oil, Petroleum Base
  • Non-flammable hydraulic fuels in the group HFD
  • Silicone oil and grease
  • Mineral and vegetable oil and grease
  • Aliphatic hydrocarbons (fuel, butane, propane, natural gas)
  • Aromatic hydrocarbons (benzene, toluene)
  • Chlorinated hydrocarbons (trichlorethylene and carbon tetrachloride)
  • Chlorine Water
  • Gasoline, Fuels, also fuels with ethanol, methanol content
  • Liquefied Petroleum Gas (LPG)
  • Natural Gas
  • Propane
  • Diesel Oil
  • High vacuum
  • Very good ozone, weather and aging resistance.
