WARCO BILTRITE is proud to be a Viton™ brand licensee. All of our Viton™ fluoroelastomer products are manufactured with 100% virgin Viton™ polymer.

Viton™ is the most specified brand of fluoroelastomer for fuel system seals, expansion joints and gaskets.

Fluoroelastomers were originally introduced over 50 years ago to meet the needs of the aerospace industry for a high-performance elastomer. Since then, the use of fluoroelastomers has spread quickly to many other industries, including the automotive, oil, fluid power, appliance and chemical industries and has developed a reputation for its outstanding performance in very hot and extremely corrosive environments.

Fluoroelastomers are particularly valued for their excellent heat stability (200°C) and resistance to aggressive fuels and chemicals.
