Material Options for Viton® Fluorocarbon O-Rings

We work with a variety of Viton® material options. The Viton® family of fluorocarbon materials is comprised of copolymers of HFP (hexafluoropropylene) and VDF or VF2 (vinylidene fluoride); terpolymers of TFE (tetrafluoroethylene), VDF (vinylidene fluoride), and HFP (hexafluoropropylene); and PMVE (perfluoromethylvinylether) containing specialty additives. Most grades of Viton® include 66-70% fluorine content.

A (Dipolymers of VF2/HFP)

Type A Viton® polymers are used for general purpose o-rings, including automotive and aerospace applications. These materials feature 66% fluorine content.

B (Terpolymers of VF2/HFP/TFE)

Type B Viton® polymers are formulated for use in chemical processing plants, power/utility applications, and the like. These materials include 68% fluorine content.

F (Terpolymers of VF2/HFP/TFE)

Type F Viton® o-rings and seals are highly resistant to oxygenated automotive fuels, concentrated aqueous inorganic acids, water, and steam. Fluorine content of these materials is roughly 70%.

Specialty Viton® Materials

Specialized types of Viton® include GLT, GBLT, GFLT, and Viton® extreme (copolymers of TFE/propylene and ethylene/TFE/PMVE). These materials are ideal for automotive applications, oil exploration, special sealing requirements, and ultra-harsh environments.
