Part number E80PC105 is an AS568-105 black EPDM (EPR) 80 Shore A O-Ring built to an inside diameter of 0.143 in (3.63 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.349 in (8.86 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.
As a material, EPDM (EPR) is specified for good electrical insulating characteristics and very good flexibility at low temperature. The compound resists phosphate ester hydraulic fluids, dilute acids and alkalis, and ketones. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). It should not be specified for service in aromatic hydrocarbons or mineral oil-based lubricants.
Maintenance and OEM teams specify it across brake and phosphate ester systems, solar and roofing assemblies, and water and steam systems.
This item is sold individually under part number E80PC105. Nominal inside diameter is listed as 5/32 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
