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 |
