7. O-RING CHEMICAL COMPATIBILITY
The following O-ring and gasket compatibility chart (Table 3) is provided as an aid in selecting
a specific synthetic rubber compound for a particular application situation. Operating
conditions and environment must also be considered in determining the media suitability.
For recommendations regarding fluids not listed, consult Sterlitech. The recommendations
represent compatibility of materials only and do not necessarily constitute a recommendation
for use in a specific application.
