Viton is a registered trademark name of the Chemours Company, a brand of synthetic rubber and fluoropolymer elastomer and the material is also known as Fluorocarbon or FKM. Standard durometer is 75 and 90 and is made in Black or Brown. The temperature range is generally -15°to 400°F.

FKM has good resistance to petroleum products and a wide spectrum of chemical compatibility. Recommended uses a vacuum, most acids, and chemicals, halogenated hydrocarbons, di-ester lubricants, petroleum oils and fuels, silicone oils and greases. FKM has excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals.

FKM is not recommended for ketones, auto and aircraft brake fluids, amine (ammonia), acetone, skydrol, ethyl acetate, hot water and steam and low molecular esters and ethers.

Low temperature resistance is normally not favorable and for static applications is limited of approximately -15°F. Under dynamic conditions, the lowest service temperature is between -5°F to 0°F.

FKM has good wear resistance, excellent compression set resistance, moderate short-term resilience, and excellent permeation resistance. It is good for vacuum service and low gas permeability.

We offer same-day shipping and perform quality checks of every order.
