APG stocks the E80PC274, an AS568-274 black EPDM (EPR) 80 Shore A O-Ring with an inside diameter of 9.984 in (253.59 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 10.262 in (260.65 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.
EPDM (EPR) is specified here for very good flexibility at low temperature and good electrical insulating characteristics. Expect good resistance to ozone, UV and weathering, water and steam, and brake fluid. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. Verify compatibility before use with aromatic hydrocarbons or mineral oil-based lubricants.
You will find this material specified across HVAC and refrigeration, water and steam systems, and potable water applications.
Reference part number E80PC274 when ordering; the item is sold individually. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
