Viton or Fluorocarbon is a brand of synthetic rubber and fluoropolymer elastomer.


Viton O Rings

Viton Fluoroelastomer / fluorocarbon / FKM

Viton or Fluorocarbon is a brand of fluoropolymer elastomer and synthetic rubber.  It combines high outstanding chemical resistance with great high temperature resistance. This makes fluorocarbon based compounds almost ideal for a universal O Ring material.

Viton has wide chemical resistance and superior performance, especially in high temperature application in different media.

Fluoroelastomers are categorised under the ASTM D1418 & ISO 1629 designation of FKM. This class of elastomers is a family comprising of copolymers and terpolymers.


The fluorine content of the most common grades varies between 66 and 70%.

The performance of fluoroelastomers in aggressive chemicals depends on the nature of the base polymer and the compounding ingredients used for moulding the final products (e.g. O-rings, shaft seals). This performance can vary significantly when end-users purchase polymer containing rubber goods from different sources.


Fluoroelastomers are generally compatible with hydrocarbons, but incompatible with ketones such as acetone and organic acids such as acetic acid.
