EPDM O Rings have great acceptance in the sealing world because of its excellent resistance to heat, water and steam, alkali, mild acidic and oxygenated solvents, ozone, and sunlight (UV). These compounds also withstand the effect of brake fluids and Skydrol" and other phosphate ester-based hydraulic fluids. They are not recommended for applications with petroleum oils, mineral oil, di-ester lubricants, or fuel exposure. Ethylene Propylene has gained wide seal industry acceptance for its excellent ozone and chemical resistance properties and is compatible with many polar fluids that adversely affect other elastomers.
