Product Specification

-
The E5.7X279.3 is a black EPDM (EPR) 70 Shore A O-Ring supplied with an inside diameter of 279.3 mm (10.996 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 290.7 mm (11.44 in). This o-ring delivers dependable bidirectional sealing in a compact groove envelope. Additional detail on this item: Metric O-RING, JIS G280.

As a material, EPDM (EPR) delivers outstanding weather, ozone and sunlight resistance, good electrical insulating characteristics. The compound resists brake fluid, phosphate ester hydraulic fluids, and ketones. The material carries a published service range of -65°F (-53.9°C) to 300°F (148.9°C). Exposure to mineral oil-based lubricants or petroleum oils and fuels will shorten service life.

Common environments for this compound include HVAC and refrigeration, outdoor equipment, and water and steam systems.

E5.7X279.3 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
