This o-ring is supplied in AS568-260 clear Polyurethane (AU/EU) 90 Shore A measuring an inside diameter of 6.484 in (164.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 6.762 in (171.75 mm), catalogued under part number U90260. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.
As a material, Polyurethane (AU/EU) is known for long wear life in dynamic reciprocating service and toughness that outperforms conventional rubber compounds. It resists extrusion under high pressure, petroleum oils, and abrasion and wear. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). Exposure to acids and bases or hot water and steam will shorten service life.
Maintenance and OEM teams specify it across hydraulic cylinders, press and forming equipment, and high-pressure fluid power.
This item is sold individually under part number U90260. 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.
