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|
|Order by Rating|
