568-411 URETHANE 90 ORINGS -PREM GRADE

This o-ring is supplied in AS568-411 clear Polyurethane (AU/EU) 90 Shore A with an inside diameter of 2.725 in (69.22 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.275 in (83.19 mm), catalogued under part number U90411. It remains the most cost-effective sealing element available for pressurized assemblies.

Polyurethane (AU/EU) is specified here for toughness that outperforms conventional rubber compounds, very high tensile strength and load capacity. The material holds up against petroleum oils, impact and shock loading, and abrasion and wear. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. It is not the right choice where acids and bases or hot water and steam are present.

It sees regular use in off-highway equipment, hydraulic cylinders, and construction machinery.

Order part number U90411, sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
