Ordered as E70452, this is an AS568-452 black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 11.475 in (291.47 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 12.025 in (305.44 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
It resists phosphate ester hydraulic fluids, ozone, UV and weathering, and water and steam. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for good electrical insulating characteristics, excellent hot water and steam resistance. Service temperature is rated from -65°F (-53.9°C) through 300°F (148.9°C). It is not the right choice where petroleum oils and fuels or mineral oil-based lubricants are present.
Typical settings include brake and phosphate ester systems, HVAC and refrigeration, and outdoor equipment.
Reference part number E70452 when ordering; the item is sold individually. Unit weight is approximately 42.075 g. Review your operating media and conditions against this specification before installation.
