The U70267 is an AS568-267 clear Polyurethane (AU/EU) 70 Shore A O-Ring built to an inside diameter of 8.234 in (209.14 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 8.512 in (216.2 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
Polyurethane (AU/EU) is specified for long wear life in dynamic reciprocating service, very high tensile strength and load capacity. It 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). It should not be specified for service in hot water and steam or prolonged humidity at elevated temperature.
It sees regular use in high-pressure fluid power, off-highway equipment, and mining and heavy equipment.
Stocked as U70267 and sold individually. Nominal inside diameter is listed as 8 1/4 inch. 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.
