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: |
(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 |

Order by Rating | |
