568-392 URETHANE 90 ORINGS -PREM GRADE

The U90392 is an AS568-392 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 22.94 in (582.68 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 23.36 in (593.34 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists petroleum oils, abrasion and wear, and extrusion under high pressure. Polyurethane (AU/EU) offers toughness that outperforms conventional rubber compounds and long wear life in dynamic reciprocating service. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Applications involving ketones or acids and bases call for a different compound.

Maintenance and OEM teams specify it across off-highway equipment, hydraulic cylinders, and mining and heavy equipment.
