Viton® Rubber Gaskets

As rubber specialists, at Martin’s Rubber, we supply a wide variety of punched, cut, extruded, sheet and fabricated Viton® rubber gaskets.

What is a Viton® (FKM) gasket?

Viton Rubber GasketsA Viton® rubber gasket is a mechanical seal which fills a void between two or more surfaces in order to prevent any leaks. Viton® gaskets, or FKM gaskets, have an excellent resistance to a combination of heat and oil and therefore hot greases that can be found in engines and compressors. In fact, Viton® flange gaskets have such an exceptionally good resistance, that they maintain functionality at temperatures that may be detrimental to other non-fluorinated elastomers. Further to this, FKM gaskets have an excellent resistance to various concentrated acids.

Viton® flange gasket properties

Viton® flange gaskets are constructed from a high performance synthetic rubber material with exceptional properties. FKM gaskets work particularly well in environments dealing with aggressive media, such as chemicals and fuels. Viton® gaskets are manufactured using a highly resilient and flexible material and are able to operate at extremely high and low temperatures of -10°C to +120°C.

For further information about the properties of Viton® rubber gaskets, please read through our Viton® rubber gasket material specification (data sheet).

What are Viton® gaskets used for?

Viton® rubber gaskets, or Fluorel / FKM gaskets, are recommended for use in applications with fuels, hydrocarbons and some acids, as well as silicone fluids and greases. However, Viton® gaskets would not be suitable for use with ketones, amines, and hot hydrofluoric or chlorosulfonic acids, in which case we may recommend you opt for a gasket in an alternative material, like solid rubber EPDM.
