EPDM compounds are used frequently to seal in brake systems, and for sealing hot water and steam. EPDM compounds have good resistance to mild acids, detergents, alkalis, silicone oils and greases, ketones, and alcohols. They are not recommended for applications with petroleum oils, mineral oil, di-ester lubricants, or fuel exposure. EPDM has excellent ozone and chemical resistance properties and is compatible with many polar fluids.
