Product Description

Ethylene Propylene Diene Monomer (EPDM) provides very good resistance to weathering, ozone and UV exposure. It is highly recommended for applications where the elastomer will have excessive exposure to the environment. EPDM provides excellent electrical resistance and is temperature resistant to 220 F. Excellent resistance to animal and vegetable oils, water, steam and oxygenated solvents. High speed centerless grinding combined with automatic gauging assures consistent part quality with close tolerances on both spherical and diametric dimensions. The resulting uniform finish ensures consistent sealing performance regardless of how the ball seats.
