Frequently Asked Questions

EPDM is a synthetic rubber with good resistance to weathering and many chemicals.

It fits systems requiring a 21.5" EPDM inflatable seal; compatibility should be confirmed with your parts diagram.

EPDM resists many waterborne coatings well but check specific solvent compatibility charts where necessary.

EPDM offers wider chemical resistance compared to Buna‑N but may be less oil/solvent resistant.
