568-032 URETHANE 90 ORINGS -PREM GRADE

Ordered as U90032, this is an AS568-032 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 1.864 in (47.35 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.004 in (50.9 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Polyurethane (AU/EU) is specified here for very high tensile strength and load capacity, toughness that outperforms conventional rubber compounds. The compound resists impact and shock loading, ozone, and abrasion and wear. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Exposure to hot water and steam or ketones will shorten service life.

Maintenance and OEM teams specify it across press and forming equipment, high-pressure fluid power, and construction machinery.

This item is sold individually under part number U90032. Nominal inside diameter is listed as 1 7/8 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.
