*568-008 URETHANE 90 ORINGS -PR GRADE

Part number U90008 is an AS568-008 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 0.176 in (4.47 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.316 in (8.03 mm). An 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) is known for outstanding extrusion resistance at elevated pressure and exceptional abrasion resistance. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C).

It sees regular use in mining and heavy equipment, high-pressure fluid power, and hydraulic cylinders.
