Solutions for Heat Hardening & Oxidation

Failure Pattern
Seen in both static and dynamic seals, when heat hardening and oxidation occurs, the surface of the O-ring appears pitted and/or cracked, often accompanied by the flatness of high compression set.

Problem Sources
Excessive temperature causing elastomer hardening, evaporation of plasticizers and cracking from oxidation.

Suggested Solutions
  • Specify high temperature O-ring materials with antioxidants
  • Lower operating temperature
