Viton® Rubber

Viton® rubber, a specific fluoroelastomer polymer (FPM), was introduced into the aerospace industry in 1957 to fulfill its needs for a high-performance elastomer.

Following its introduction, the usage of Viton® spread quickly to other industries including the automotive, appliance, chemical and fluid power industries. Viton® has a strong reputation as a high-performance elastomer in very hot and extremely corrosive environments. Viton® was also the first fluoroelastomer to obtain worldwide ISO 9000 registration.

Viton® is a registered trademark of DuPont Performance Elastomers.

Applications image

Applications

For example, Viton® O-rings with a service temp. of -45°C to +275°C will also resist the effects of thermal cycling, which are encountered during the rapid ascent and descent of aircraft from the stratosphere.

Viton's® effectiveness to perform against extremes of heat, chemicals, and fuel mixtures allows it to be used for:

  • fuel seals
  • quick-connect O-rings
  • head & intake manifold gaskets
  • fuel injection seals
  • advanced fuel hose components

Examples of applications and industries where Viton® is used include:

Aerospace & Aircraft Industry

The high performance properties of Viton® can be seen in many aircraft components including:

  • Radial lip seals used in pumps
  • Manifold gaskets
  • Cap-seals
  • T-Seals
  • O-rings used in line fittings, connectors, valves, pumps, and oil reservoirs
  • Siphon hoses

Automotive Industry

Viton® has oil resistant properties that make it the perfect under-hood material. Viton® is used for:

  • Gaskets
  • Seals
  • O-rings

Food Industry

Pharmaceutical Industry



Benefits & Advantages image

Benefits & Advantages

Broad Chemical Compatibility

Viton® materials are compatible with many chemicals

  • lubricating and fuel oils
  • hydraulic oil
  • gasoline (high octane)
  • kerosene
  • vegetable oils
  • alcohols
  • diluted acids
  • and more

Comparing capabilities is important if you're considering a change in materials to increase reliability or accommodate more severe operating conditions.

Temperature Stability

Many applications require rubber parts to be stressed by accidental temperature excursions as well as increased operating temperatures to allow for increases in production. In certain instances, Viton® has been known to perform continuously at 204°C and even after short excursions to 315°C. Certain grades of Viton® rubber can also perform equally well in temperatures as low as -40°C.

FDA Compliant

If FDA compliance is necessary, Timco Rubber has access to certain types of Viton® materials that meet FDA requirements for food and pharmaceutical applications.

Meets Strict Environmental Regulations

As environmental regulations have raised the stakes against emissions, spills and leaks, Viton® high-performance seals have filled the gap where other elastomers fall short.
