Compound

Viton (FKM)

The premium fluoroelastomer for aggressive chemicals and sustained high heat. Specified where a nitrile part is failing early and downtime costs more than the seal.

Service range
−20 °C to +230 °C

Why specify FKM

  • Resists most acids, solvents, fuels and aggressive chemicals
  • Continuous service to 200 °C and above, with higher excursions
  • Very low gas permeability
  • Excellent compression set at temperature

Where it fails

Significantly more expensive than NBR and poor below −20 °C. Not suitable for hot water, steam, ketones or amines.

We would rather talk you out of the wrong compound than sell you a part that comes back in three months. If the duty is borderline, send the operating conditions and we will say so plainly.

Typical components in FKM

  • Chemical dosing pump seals and valve plates
  • High-temperature O-rings
  • Solvent-handling gaskets
  • Submersible pump valve plates

Compare with other compounds

Send a drawing, a sample, or just a photo of the worn part.

We will identify the compound, quote the tooling and get a first sample to you. No drawing needed — a measured sketch or the old component is enough to start.
