Part number E70107 is an AS568-107 black EPDM (EPR) 70 Shore A O-Ring measuring an inside diameter of 0.206 in (5.23 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.412 in (10.46 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
It resists dilute acids and alkalis, ozone, UV and weathering, and water and steam. That behavior comes from the compound itself: EPDM (EPR) is specified for excellent hot water and steam resistance, very good flexibility at low temperature. Rated temperature range runs from -65°F (-53.9°C) to 300°F (148.9°C) in continuous service. Applications involving mineral oil-based lubricants or aromatic hydrocarbons call for a different compound.
You will find this material specified across water and steam systems, potable water applications, and brake and phosphate ester systems.
Reference part number E70107 when ordering; the item is sold individually. Unit weight is approximately 3.9389 g and nominal inside diameter is listed as 7/32 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
