The E70171 is an AS568-171 black EPDM (EPR) 70 Shore A O-Ring measuring an inside diameter of 7.987 in (202.87 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 8.193 in (208.1 mm). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.
EPDM (EPR) offers outstanding weather, ozone and sunlight resistance, strong performance in outdoor and exposed installations. The compound resists ketones, dilute acids and alkalis, and water and steam. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). Exposure to petroleum oils and fuels or mineral oil-based lubricants will shorten service life.
Maintenance and OEM teams specify it across solar and roofing assemblies, water and steam systems, and outdoor equipment.
Order part number E70171, sold individually. Unit weight is approximately 4.07 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
