Extreme Viton® O-Rings Overview

Extreme Viton® o-rings are a copolymer of ethylene, tetrafluoroethylene, and perfluoromethylvinyl ether, otherwise known as Viton® ETP. Viton® ETP o-rings maintain the strong chemical resistance of standard Viton® o-rings, with the added capability of withstanding ketones, esters, and aldehydes of low molecular weight. Viton® ETP o-rings are frequently utilized in the oil and gas, aerospace, and automotive industries.

Global O-Ring and Seal’s Viton® ETP o-rings are peroxide-cured and supplied in 75 durometer. If you would like more information or to request a quote on Viton® ETP o-rings, please give us a call at 832-448-5550 or submit the Product Inquiry form.

Advantages of Viton® ETP O-Rings:

With built-in protection against highly acidic fluids and base materials, Viton® ETP o-rings are not made to swell or lose their compression set when facing aggressive solutions, amines, and hot water. Additionally, the elastomer’s flexibility is effectively maintained at low temperatures. With outstanding resistance versus harsh chemicals, Viton® ETP’s performance is similar to that of FFKM (perfluoroelastomers), but at a lower price point.
