568-386 URETHANE 90 ORINGS -PREM GRADE

Ordered as U90386, this is an AS568-386 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 16.955 in (430.66 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 17.375 in (441.33 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to ozone, extrusion under high pressure, and impact and shock loading. Polyurethane (AU/EU) offers long wear life in dynamic reciprocating service, very high tensile strength and load capacity. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with hot water and steam or ketones.

Typical settings include high-pressure fluid power, hydraulic cylinders, and construction machinery.
