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.

Natural rubber is a product coagulated from the latex of the rubber tree, hevea brasiliensis. Natural rubber features low compression set, high tensile strength, resilience, abrasion and tear resistance, good friction characteristics, excellent bonding capabilities to metal substrate, and good vibration dampening characteristics.

Chloroprene Rubber is moderately resistant to both petroleum oils and weather (ozone, UV, oxygen). This qualifies Chloroprene uniquely for certain sealing applications where many other materials would not be satisfactory. Chloroprene has relatively low compression set, good resilience and abrasion, and is flex cracking resistant. Chloroprene has excellent adhesion qualities to metals for rubber to metal bonding applications. It is used extensively for sealing refrigeration fluids due to its excellence resistance to Freon and ammonia.
