-033 BLACK EPDM 70D O-RING

Ordered as E70033, this is an AS568-033 black EPDM (EPR) 70 Shore A O-Ring measuring an inside diameter of 1.989 in (50.52 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.129 in (54.08 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Expect good resistance to ketones, brake fluid, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) is specified for strong performance in outdoor and exposed installations, very good flexibility at low temperature. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). Exposure to petroleum oils and fuels or aromatic hydrocarbons will shorten service life.

Typical settings include outdoor equipment, brake and phosphate ester systems, and HVAC and refrigeration.
