568-441 URETHANE 90 ORINGS -PREM GRADE

Ordered as U90441, this is an AS568-441 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 6.975 in (177.17 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 7.525 in (191.14 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Polyurethane (AU/EU) is widely chosen for very high tensile strength and load capacity, exceptional abrasion resistance. This material stands up to extrusion under high pressure, petroleum oils, and abrasion and wear. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with prolonged humidity at elevated temperature or ketones.

Common environments for this compound include high-pressure fluid power, construction machinery, and mining and heavy equipment.

Reference part number U90441 when ordering; the item is sold individually. Nominal inside diameter is listed as 7 inch. 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.
