This o-ring is supplied in AS568-327 black EPDM (EPR) 80 Shore A built to an inside diameter of 1.725 in (43.82 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.145 in (54.48 mm), catalogued under part number E80PC327. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.
The compound resists phosphate ester hydraulic fluids, water and steam, and ozone, UV and weathering. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for good electrical insulating characteristics and very good flexibility at low temperature. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). Applications involving petroleum oils and fuels or mineral oil-based lubricants call for a different compound.
Maintenance and OEM teams specify it across brake and phosphate ester systems, HVAC and refrigeration, and outdoor equipment.
E80PC327 ships individually. Nominal inside diameter is listed as 1 3/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
