Viton® Material Description
Viton® is a trade name for the Chemours brand of fluorocarbon, also known as FKM. FKM is a well-known high-performance rubber that has excellent resistance to high temperature, ozone, weather, oxygen, mineral oil, fuels, hydraulic fluids, aromatics and many organic solvents and chemicals.
Viton® o-rings are preferable for use with petroleum products, fuels, mineral oil and grease, silicone oil and grease, strong acids, high vacuum conditions, and conditions requiring weather resistance. Viton® o-rings are not preferable for use with ketones, superheat steam, phosphate ester-based hydraulic fluids, and low molecular weight organic acids, esters and ethers.
Viton® variations include: Viton® A, Viton® B, Viton® F, Viton® GLT, Viton® GFLT, Viton® Extreme (a.k.a. Viton® ETP)
Viton® general type (A: 66% fluorine), middle fluorine content type (B, GBL: 67 to 68.5% fluorine), high fluorine content type (F, GF: 70% fluorine), improving low temperature flexibility type (GLT, GFLT) and excellent resistance to more chemicals and solvents (Viton® ETP Extreme). We also can supply excellent acid and alkali resistance parts made by Viton® TBR. Viton® o-rings may also come in a metal detectable variation, while retaining the same qualities as the general Viton® o-ring compound.
For more detailed information on specific types of Viton®, please download the Viton® Selection Guide.
Standard FKM o-ring compounds are bisphenol-cured. FKM o-ring compounds with peroxide-cured possess better acid solution resistance than the bisphenol-cured and can replace litharge-cured applied in acid solutions. In some lubricants, adding a few organic amide or amine, or choosing peroxide-cured system Viton® o-rings will be better than bisphenol curing systems.
