Chemical resistance
Can be usedDo not use
Mineral oil, grease and hydraulic oil (H, H-L, H-LP)Brake fluid (DOT 3, DOT 4, DOT 5.1): the ring swells quickly
Diesel, fuel oil, keroseneSunlight and open air (ozone): the rubber cracks
Petrol (gasoline), propane, butaneAcetone, MEK, ethyl acetate and similar solvents
Water and water-based liquids, up to +80 °CBenzene, toluene, trichloroethylene (aromatic and chlorinated solvents)
Compressed air, also with oil mistSynthetic ester oils and fire-resistant fluid HFD-R
Water-based fire-resistant hydraulic fluids (HFA, HFB, HFC)Strong (concentrated) acids, e.g. nitric and sulfuric, and strong oxidizers
Oil-and-water emulsionsSteam and hot water above +100 °C
Weak acids, alkalis and salt solutions, at room temperature
