*568-227 URETHANE 90 ORINGS -PREM GRADE

This o-ring is supplied in AS568-227 clear Polyurethane (AU/EU) 90 Shore A measuring an inside diameter of 2.109 in (53.57 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.387 in (60.63 mm), catalogued under part number U90227. It remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Polyurethane (AU/EU) is widely chosen for exceptional abrasion resistance and long wear life in dynamic reciprocating service. It resists abrasion and wear, petroleum oils, and ozone. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). It should not be specified for service in ketones or acids and bases.

You will find this material specified across hydraulic cylinders, construction machinery, and high-pressure fluid power.

Stocked as U90227 and sold individually. Nominal inside diameter is listed as 2 1/8 inch. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
