E101 is a black Ethylene-Propylene-Diene Rubber, commonly referred to as EPDM. It is used in hot water or steam applications, glycol-based brake fluids, alkalis and fire-resistant fluids (HFC), and some phosphate esters. E101 is also used in bases, acids, and alcohols. E101 is not resistant to mineral oil-based fluids, diester-based lubricants, aromatic fuels, or vegetable and animal oils.

E101 is used for standard and special sealing applications such as hydraulic or rotary seals, O-rings, flange seals and gaskets.

Temperature Range: -58°F to 266°F (-50°C to 130°C)
