FKM Viton®

FPM/FKM Viton®

We believe that fluorcarbon rubber, FKM Viton®, is the most significant elastomer developed in recent history. 

What is FPM/FKM Viton®? 

The terms Viton® O-rings, FPM and FKM often lead to confusion and incorrect interpretations. 

FPM is the ISO designation, FKM is the ASTM designation. Viton®, Dai-El and Technoflon are brands for FPM polymers. All of the designations stand for one single base material, which is fluoro rubber.

This rubber is used in applications that need O-rings that are resistant to high temperatures and chemical attacks. The FPM/FKM Viton® sealing rings are often used aircraft, automobile and other mechanical devices requiring maximum resistance to elevated temperatures and to many fluids, or other media.

Why is FPM/FKM Viton® the most significant elastomer developed?

  • FPM/FKM Viton® has a wide temperature range
  • FPM/FKM Viton® has excellent aging characteristics
  • Low compression set
  • Wide range of chemical compatibility
  • FPM/FKM Viton® is resistant chemical and ozone attacks
  • Temperature range -26°C to +205°/230°C (-15°F to +400°/440°F)

To which media is FPM/FKM Viton® resistant?

FPM/FKM Viton® is highly resistant against:

  • Mineral and vegetable oils and greases
  • Non-flammable hydraulic fluid
  • Organical solvents and chemicals
  • Diesel fuels and Petrol
  • Acids
  • Aromatic and chlorinated hydrocarbons
  • Aliphatic
