Product Description

FKM O-Ring and seal performance cost benefit makes it the second most popular sealing material. Fluoroelastomer (FKM) offers a wide range of resistance to chemicals, oil and heat, with situational service life above 200°C. The outstanding heat stability and excellent resistances are due to the high ratio of fluorine to hydrogen, the strength of the carbon-fluorine bond, and the absence of unsaturation. FKM compounds are widely used in chemical, automotive, aerospace and industrial applications. Fluoroelastomers are referred to generically as FKM polymers per the nomenclature noted in ASTM D1418. 
Features Of FKM O-Rings:
  • Situational service life above 200°C
  • Excellent resistance to acids, fuels, mineral and vegetable oils and greases, aliphatic, aromatic and chlorinated hydrocarbons, non-flammable hydraulic fluids (HFD) and many organic solvents and chemicals.
  • Excellent resistance to aging and ozone.
  • Low gas permeability, low compression set.
Limitations of FKM O-Rings:
  • Ketones (MEK,and Acetone) and Skydrol fluids.
  • Amines and Anhydrous Ammonia.
  • Low molecular weight esters and ethers. Hot hydrofluoric or chlorosulfonic acids and low molecular weight organic acids (formic and acetic acids).
  • Polar solvents, low molecular weight organic solvents and glycol-based brake fluids
