This o-ring is supplied in AS568-118 black EPDM (EPR) 70 Shore A built to an inside diameter of 0.862 in (21.89 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.068 in (27.13 mm), catalogued under part number E70118. It delivers dependable bidirectional sealing in a compact groove envelope.
Expect good resistance to dilute acids and alkalis, phosphate ester hydraulic fluids, and water and steam. That behavior comes from the compound itself: EPDM (EPR) delivers very good flexibility at low temperature, outstanding weather, ozone and sunlight resistance. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. Exposure to petroleum oils and fuels or mineral oil-based lubricants will shorten service life.
Maintenance and OEM teams specify it across potable water applications, outdoor equipment, and water and steam systems.
Reference part number E70118 when ordering; the item is sold individually. Unit weight is approximately 0.0005 g and nominal inside diameter is listed as 7/8 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.
