This page contains a guide to selecting O-ring materials based on chemical compatibility requirements.

The chemical compatibility data can be presented in one of two ways. First, you can select a specific O-ring material to view its compatible chemicals. Or second, you can select a specific chemical to view all its compatible O-ring materials.

Chemical compatibilities are rated and displayed according to the following scale:

  Key to O-Ring Material Compatibility Ratings  
 (4)   Good, both for static and dynamic seals
 (3)   Fair, usually OK for static seals
 (2)   Sometimes OK for static seals; not OK for dynamic seals
 (1)   Poor
 (0)   No Data
