Fluorocarbon (Viton)

McMasters Koss Fluorocarbon O-Rings
Classic Building

Fluorocarbon elastomer or Fluoroelastomers (as commonly called) were originally developed by the Dupont Company and marketed under the trade name of Viton.

Designed with a high strength fluorine-hydrogen bond, this elastomer provides superior resistance to extreme temperatures and a wide variety of chemicals.

Automotive Engine

Severe service equipment manufacturers quickly adopted fluorocarbon and have utilized it in a wide variety of automotive, industrial, petrochemical and semi-conductor applications.

Truck in Snow

Fluorocarbon is available in a number of fluorination levels to provide higher levels of chemical or low temperature performance.

Specialty fluorocarbon elastomers have been developed to provide superior performance in specific caustic chemicals and a lower low temperatures.

Chemical Processing

The standard type A fluorocarbon provide good performance at constant temperatures up to 400F and intermittently up to 600F with moderate low temperature performance.
