568-920 URETHANE 90 ORINGS -PREM GRADE

Ordered as U90920, this is an AS568-920 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 1.475 in (37.47 mm), a cross section of 0.118 in (3 mm), and an outside diameter of 1.711 in (43.46 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to abrasion and wear, extrusion under high pressure, and ozone. That behavior comes from the compound itself: Polyurethane (AU/EU) delivers toughness that outperforms conventional rubber compounds and exceptional abrasion resistance. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). Verify compatibility before use with ketones or hot water and steam.

Common environments for this compound include press and forming equipment, hydraulic cylinders, and construction machinery.
