*568-212 URETHANE 90 ORINGS -PR GRADE

Part number U90212 is an AS568-212 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 0.859 in (21.82 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.137 in (28.88 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Polyurethane (AU/EU) delivers toughness that outperforms conventional rubber compounds and exceptional abrasion resistance. This material stands up to abrasion and wear, extrusion under high pressure, and impact and shock loading. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Exposure to hot water and steam or prolonged humidity at elevated temperature will shorten service life.

Common environments for this compound include construction machinery, mining and heavy equipment, and press and forming equipment.
