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:
|Order by Rating|
