Why Fluoroelastomer (FKM) Works for Most Projects
Most challenging applications find their solution in FKM elastomers. These materials tackle high chemical resistance requirements and temperatures up to 400°F (204°C). Thanks to their 66-70% fluorine content, FKM seals resist fuels, oils, solvents, and corrosive chemicals. It’s ideal for automotive, industrial, and oil/gas applications where you need more than standard rubber, but still want to save on costs.
Why Some Applications Need Perfluoroelastomer (FFKM)
Some applications simply can’t compromise on seal performance. When you’re dealing with universal chemical compatibility across 1,800+ chemicals and solvents, or temperatures that push beyond 400°F up to 600°F (325°C), perfluoroelastomers are your only option. The fully fluorinated backbone creates unmatched chemical inertness, making FFKM the go-to choice for many semiconductor, pharmaceutical, and aerospace applications.
Frequently Asked Questions
What are Viton gaskets used for?
Viton gaskets are used in aerospace, chemical, automotive, industrial, and oil/gas applications, as well as semiconductor and pharmaceutical processing where FFKM grades are required for absolute purity.
What temperature range can Viton gaskets handle?
Standard FKM Viton compounds handle -15°F to +400°F. For applications that push beyond that, FFKM perfluoroelastomer seals extend the range up to 600°F.
What is the difference between Viton A, B and F?
The grades differ by fluorine content: Viton A is 66% fluorine, Viton B is 68%, and Viton F is 70%. Higher fluorine content generally means better chemical resistance.
Is Viton better than EPDM?
Neither is universally “better,” as they solve different problems. Viton (FKM) is the stronger choice for oil, fuel, and aggressive chemical exposure, and it handles higher continuous heat, up to 400°F, versus EPDM’s roughly 300°F ceiling. EPDM performs better in outdoor, UV-exposed, and water/steam applications and tends to stay flexible at lower temperatures than standard Viton grades. The deciding factor is usually what the seal will contact, not which material is “premium.”
