568-047 URETHANE 90 ORINGS -PREM GRADE

U90047 is an AS568-047 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 4.489 in (114.02 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 4.629 in (117.58 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against ozone, petroleum oils, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) offers toughness that outperforms conventional rubber compounds and long wear life in dynamic reciprocating service. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with acids and bases or hot water and steam.

Typical settings include high-pressure fluid power, press and forming equipment, and hydraulic cylinders.
