EPDM should not be used with oils and fuels as these cause swelling. The upper limit to strength is around 1100 PSI.
Good Applications for EPDM Rubber Gaskets
EPDM works where the application needs a gasket material more robust than neoprene and less expensive than silicone. The three main classes of application are:
Food and drink processing equipment (mixer seals is a common application) as it’s available in food grades and withstands aggressive cleaning regimens.
Sealing outdoors, where it withstands low temperatures and exposure to UV.
Electrical cabinets and enclosures, where ozone may be generated.
