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.
This item is sold individually under part number E70033. Unit weight is approximately 0.0005 g and nominal inside diameter is listed as 2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
