75 Durometer FKM/VITON® (Fluoroelastomer) is a high-performance fluoroelastomer sheet material at 75 Shore A, formulated for demanding sealing applications where resistance to aggressive chemical environments is the primary design requirement.
With 66% fluorine content, it exhibits resistance to a broad range of oils, fuels, lubricants, and most mineral acids, and provides very good resistance to aliphatic hydrocarbon fluids that can dissolve many other types of rubber. These properties make it the material of choice for fuel and oil system gaskets, high-temperature sealing, and solvent-resistant applications across automotive, aerospace, industrial, and chemical processing industries.
The -20°F to 400°F service temperature range reflects FKM’s inherent thermal stability at elevated temperatures.
This material is produced with no regrind and no recycled materials, is Made in the USA, and is cinnamon scented. Other durometers are available. It passes California Proposition 65.
Compliant with CA Prop 65 — Pass.
What differentiates 75 Durometer FKM/VITON® (Fluoroelastomer) from other rubber gasket materials?
75 Durometer FKM/VITON® (Fluoroelastomer) is a fluoroelastomer with 66% fluorine content, providing a level of chemical resistance to oils, fuels, lubricants, mineral acids, and aliphatic hydrocarbons that most other rubber types — including neoprene, nitrile, EPDM, and natural rubber — cannot match. Its -20°F to 400°F service temperature range also substantially exceeds the upper limits of conventional industrial rubber grades, making it the appropriate selection for the most chemically aggressive and thermally demanding gasket applications.
Why does fluorine content matter in material selection for FKM/VITON® elastomers?
Fluorine content is the primary determinant of chemical resistance in fluoroelastomers. Higher fluorine content generally correlates with greater resistance to aggressive fluids — including fuels, aromatic solvents, and acids. At 66% fluorine content, this material provides broad resistance across oils, fuels, lubricants, and aliphatic hydrocarbon fluids that can dissolve many other rubber types, as stated on the TDS. When evaluating FKM grades for a specific fluid environment, fluorine content is a key specification parameter alongside hardness and temperature range.
What is the temperature range for 75 Durometer FKM/VITON® (Fluoroelastomer)?
75 Durometer FKM/VITON® (Fluoroelastomer) is rated for service from -20°F to 400°F, as listed on the TDS.
Is 75 Durometer FKM/VITON® (Fluoroelastomer) suitable for chemically aggressive or regulated environments?
Yes. This material resists a broad range of oils, fuels, lubricants, mineral acids, and aliphatic hydrocarbon fluids, and passes California Proposition 65, as stated on the TDS. It is produced with no regrind and no recycled materials and is Made in the USA. No additional compliance standards are specified on the TDS.
How should 75 Durometer FKM/VITON® (Fluoroelastomer) be specified?
Specify grade (75 Durometer FKM/VITON® Fluoroelastomer), thickness, compliance requirements (CA Prop 65), dimensional tolerances, and finished format. Note that other durometers are available.
