-458 BLACK EPDM 70D O-RING

APG stocks the E70458, an AS568-458 black EPDM (EPR) 70 Shore A O-Ring with an inside diameter of 14.475 in (367.67 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 15.025 in (381.64 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, EPDM (EPR) is widely chosen for strong performance in outdoor and exposed installations, outstanding weather, ozone and sunlight resistance. This material stands up to dilute acids and alkalis, phosphate ester hydraulic fluids, and ozone, UV and weathering. Continuous operating temperature is published at -65°F (-53.9°C) to 300°F (148.9°C). Exposure to mineral oil-based lubricants or petroleum oils and fuels will shorten service life.

Maintenance and OEM teams specify it across potable water applications, HVAC and refrigeration, and outdoor equipment.

Order part number E70458, sold individually. Unit weight is approximately 52.825 g and nominal inside diameter is listed as 14 1/2 inch.
