The U70376 is an AS568-376 clear Polyurethane (AU/EU) 70 Shore A O-Ring built to an inside diameter of 9.725 in (247.02 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 10.145 in (257.68 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
Polyurethane (AU/EU) offers outstanding extrusion resistance at elevated pressure and exceptional abrasion resistance. The material holds up against impact and shock loading, ozone, and petroleum oils. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). Exposure to ketones or hot water and steam will shorten service life.
Common environments for this compound include off-highway equipment, construction machinery, and hydraulic cylinders.
Reference part number U70376 when ordering; the item is sold individually. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
