-116 BLACK EPDM 70D NSF O-RING

This o-ring is supplied in AS568-116 black EPDM (EPR) 70 Shore A measuring an inside diameter of 0.737 in (18.72 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.943 in (23.95 mm), catalogued under part number E70NSF116. It delivers dependable bidirectional sealing in a compact groove envelope.

It resists ozone, UV and weathering, dilute acids and alkalis, and water and steam. That behavior comes from the compound itself: EPDM (EPR) is widely chosen for outstanding weather, ozone and sunlight resistance, strong performance in outdoor and exposed installations. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). It is not the right choice where petroleum oils and fuels or mineral oil-based lubricants are present.

This o-ring meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include solar and roofing assemblies, outdoor equipment, and brake and phosphate ester systems.

Stocked as E70NSF116 and sold individually. Unit weight is approximately 0.413 g and nominal inside diameter is listed as 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
