  • Operating temperature-45 °C to +130 / +150 °C

Good with hot water, steam, glycol brake fluid, ozone and sunlight. Never use with mineral oils, grease or fuels.

Chemical resistance
Can be usedDo not use
Hot water and steam (up to +150 °C; steam up to +180 °C with peroxide-cured rings)Mineral oil, grease and hydraulic oil (HL, HLP)
Brake fluid on a glycol basis (DOT 3, DOT 4, DOT 5.1): the standard material for brake hydraulicsEngine and gear oil, lubricating grease (incl. lithium grease)
Ozone, UV, sunlight and weather (does not crack for decades)Petrol (gasoline), diesel, kerosene, crude oil: swells quickly and loses its shape
Acetone, MEK and alcohols (ethanol, methanol, isopropanol)Toluene, xylene, hexane, turpentine (aromatic and aliphatic hydrocarbons)
Fire-resistant hydraulic fluid HFD-R (phosphate esters)Trichloroethylene, perchloroethylene (chlorinated solvents)
Dilute acids and alkalis, incl. CIP washing solutions and caustic sodaSilicone-based (DOT 5) and mineral-based (LHM) brake fluid
Detergents, washing powders and salt solutionsStrong (concentrated) oxidizing acids, e.g. nitric and sulfuric

Golden rule: no mineral oil or ordinary grease, not even to ease fitting. EPDM swells to about twice its volume and turns to jelly. Lubricate only with silicone grease or glycerin / soap solution.
