APG stocks the E1.5X8.5, a black EPDM (EPR) 70 Shore A O-Ring built to an inside diameter of 8.5 mm (0.335 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 11.5 mm (0.45 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. Source specification: Metric O-RING, JIS S9.

EPDM (EPR) is specified here for good electrical insulating characteristics, excellent hot water and steam resistance. The material holds up against ozone, UV and weathering, dilute acids and alkalis, and ketones. 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.

You will find this material specified across solar and roofing assemblies, brake and phosphate ester systems, and water and steam systems.

This item is sold individually under part number E1.5X8.5. Unit weight is approximately 0.075 g.
