About FKM (Fluoroelastomer / Viton®) O Rings
Looking for high-performance O-rings that thrive under heat and chemical pressure? FKM O-rings — also commonly known by the brand name Viton® — are your go-to solution for extreme sealing conditions.
What is FKM?
FKM stands for fluoroelastomer, a premium synthetic rubber designed to withstand:
-
Temperatures from –20 °C up to +200 °C (with peaks of 230 °C in some compounds)
-
Chemicals like fuels, oils, acids, and solvents
-
Ozone, UV and weathering over long periods
This makes them ideal for automotive, aerospace, chemical processing, and high-temperature industrial applications.
FKM vs. NBR / Silicone: What's the Difference?
| Feature | FKM (Viton®) | NBR (Nitrile) | Silicone |
|---|---|---|---|
| Temp Range | –20 °C → +200–250 °C | –40 °C → +120 °C | –50 °C → +200 °C |
| Chemical Resistance | Excellent (fuels, oils, solvents) | Moderate | Poor (especially fuels) |
| Ozone/UV Resistance | Excellent | Poor | Excellent |
| Durability / Cost | High durability, higher cost | Budget friendly | Flexible, mid-price |
