Which O-Ring performs better under temperature extremes?

If you’re sealing in extreme cold or static high heat, go for silicone. For high-temp chemicals, choose FKM.

Materialo Lowest Temp Highest Temp (Typical)
Silicono -50°C 250°C (300°C additives)
FKM -20°C 200°C (up to 300°C)

FKM for high-heat chemical sealing

When should I use Silicone or FKM O-Rings?

Use Silicone O-Rings in:

  • Food-grade or sterile systems
  • Cold storage
  • Low-pressure static sealing

Use FKM O-Rings in:

  • Automotive fuel lines
  • Hidraŭlikaj sistemoj
  • Oil, chemical, and acid environments
