The U70280 is an AS568-280 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with an inside diameter of 13.984 in (355.19 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 14.262 in (362.25 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Polyurethane (AU/EU) is specified here for long wear life in dynamic reciprocating service, very high tensile strength and load capacity. The compound resists extrusion under high pressure, abrasion and wear, and impact and shock loading. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). Applications involving ketones or prolonged humidity at elevated temperature call for a different compound.
You will find this material specified across off-highway equipment, construction machinery, and mining and heavy equipment.
This item is sold individually under part number U70280. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
