Common questions

Does EPDM resist brake fluid?

Correctly specified EPDM is commonly used with glycol-based DOT 3, 4 and 5.1 fluids. This does not automatically apply to silicone-based DOT 5. Braking systems require an approved compound.

Does EPDM resist diesel?

Standard EPDM is generally unsuitable for diesel and mineral oil.

Indicative family information. Concentration, pressure, temperature, exposure and the exact compound must be assessed. Safety-critical applications require documented application approval.
