568-447 URETHANE 90 ORINGS -PREM GRADE

U90447 is an AS568-447 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 8.975 in (227.97 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 9.525 in (241.94 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Polyurethane (AU/EU) offers toughness that outperforms conventional rubber compounds, very high tensile strength and load capacity. The compound resists ozone, abrasion and wear, and petroleum oils. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Exposure to ketones or prolonged humidity at elevated temperature will shorten service life.

Common environments for this compound include mining and heavy equipment, hydraulic cylinders, and off-highway equipment.
