2.4mm X 11.8mm V90 FKM Fluorocarbon 90 Durometer O-Ring Black (JIS P12-V90)

Metric Fluorocarbon FKM O-Rings - Cross Section "CS" X Inside Diameter "ID"

Fluorocarbon FKM O-Rings 90 Durometer (Fluorocarbon, FKM)   

            A general purpose 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.

Heat Resistance

  • Up to 400°F (204°C) and higher temperatures with shorter life expectancy.

Cold Flexibility

  • Down to –15°F (–26°C) (some to –40°F (–40°C)).

Chemical Resistance

  • Mineral oil and grease, low swelling in ASTM oil No. 1, and IRM 902 and IRM 903 oils
  • Hydraulic Oil
  • 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 methanol content
  • High vacuum
  • Very good ozone, weather and aging resistance.

Not Compatible With:

  • Glycol based brake fluids
  • Ammonia gas, amines, alkalis
  • Brake Fluid
  • Acetone
  • Superheated steam
  • Low molecular organic acids (formic and acetic acids)
  • Methyl Ethyl Ketone
