Viton® rubber, formulated by Seals Eastern, can be utilized in seals, o-rings, gaskets, packings and other applications where thermal stability and chemical resitance are required. If your seals exhibit thermal or chemical degradation, we can help you by analyzing your failures and recommending the appropriate grade of Viton to solve your problem. Let us be your trusted engineer: we have been solving sealing problems with Viton since 1960.

Seals Eastern has experience formulating and molding Viton includes Viton AHV, Viton ETP, Viton TBR, Viton B, and other Viton polymers most Viton® rubber grades including Viton A, Viton B, Viton GFLT, and Viton Extreme (also known as Viton ETP) into o-rings, gaskets, packers and other seal types. Our compounds are mixed and molded in our Red Bank, NJ factory. Generally speaking, products molded using Genuine Viton elastomers provide exceptional resistance to heat, oils, and chemicals. Viton® based elastomer formulations deliver a broad range of chemical resistance, continuous service temperatures of 400F, and low temperature capabilities down to -35F.

Most Viton® elastomers are categorized under the ASTM D1418 designation of FKM (the DIN/ISO counterpart to this designation is FPM). This class of elastomer is further categorized by types. 

Viton ETP®, also referred to as Viton Extreme, is an FEPM class material and additionally offers excellent base resistance since there is no vinylidene fluoride in the composition.

Do not be fooled by counterfeit "Viton" o-rings that often contain reground material and cheap fluorocarbon copolymers. Cheap imports will deliver inferior performance. Seals Eastern guarantees its Genuine Viton® seals are made using 100% virgin Viton polymers and are post-cured in accordance with DuPont recommendation.
