Viton® O-RINGS

O-rings that are Highly compatible with chemicals, temperature range up to 200 c, low compression set, and also excellent aging capabilities.

What is Viton®?

Viton is a synthetic rubber and fluoropolymer elastomer which is commonly used in O-rings and other molded or extruded goods. Viton is a registered trademark of Chemours.

In the toughest of environments – amid high temperatures and harsh chemicals – Viton fluoroelastomers provide peak performance and resistance. Specific for fuel systems seals and hoses, O-rings, and gaskets, Viton fluoroelastomers can outperform the competition.

Viton® / FKM O-rings

The terms Viton O-rings 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 of FKM. All of the designations stand for one single base material, which is fluoro rubber.

To ensure that you always receive the highest quality FKM products available, insist on 100% virgin Viton™ from Chemours.

Viton™ is Specified for its Outstanding Performance

  • Outstanding resistance to heat, oxidation, weathering, ozone

  • Outstanding resistance to a broad variety of fluids, including:  aliphatic and aromatic hydrocarbons, halogenated fluids, strong acids

  • Outstanding resistance to compression set, providing sealing performance and longevity unmatched by any non-fluorinated elastomer

These characteristics make Viton: fluoroelastomer the perfect choice for demanding sealing applications. Unfortunately, there are several low-cost “fluoroelastomer imposters” on the market that may put your operations at risk of seal failure. A number of manufacturers of finished goods off products which are being described as “commercial” or “industrial grades” of fluoroelastomers at reduced prices. These so-called “fluoroelastomers” can be off at lower cost simply because they are not 100% virgin fluoroelastomers Instead, some of these products are blends of FKM with hydrocarbon elastomers, such as ethylene-propylene, chloroprene or acrylic rubbers Perfluoroelastomers.


Applications of Viton® O-ring

Fluorocarbon elastomers have grown to major importance in the seal industry. Due to its wide range of chemical compatibility, temperature range, low compression set, and excellent aging characteristics, f lrubber is the most signify single elastomer developed in recent history. Fluorocarbon elastomers are highly fl carbon-based polymers used in applications to resist harsh chemical and ozone attack.


  • The working temperature range is considered to be -20°C to +200°C
  • For short working periods it will take even higher temperatures
  • Special compounds having improved chemical resistance are also
  • Low compression set and low gas permeability
  • Viton O-rings have excellent resistance to acids, mineral and vegetable oil and greases, fuels, aliphatic, aromatic and chlorinated hydrocarbons, non-fl hydraulic fl and several organically solvents and chemicals
  • Viton O-rings are exceptionally resistant to aging, chemical and ozone attacks

Viton® O-rings are resistant to

  • Silicon oils and greases
  • Mineral and oil greases
  • Aliphatic, aromatic and special chlorinated hydrocarbons
  • Petrol and Diesel fuels
  • Chemical and Ozone attacks
