*568-218 URETHANE 90 ORINGS -PREM GRADE

This o-ring is supplied in AS568-218 clear Polyurethane (AU/EU) 90 Shore A measuring an inside diameter of 1.234 in (31.34 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.512 in (38.4 mm), catalogued under part number U90218. It delivers dependable bidirectional sealing in a compact groove envelope.

The compound resists petroleum oils, extrusion under high pressure, and ozone. Polyurethane (AU/EU) is widely chosen for long wear life in dynamic reciprocating service, very high tensile strength and load capacity. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). It is not the right choice where acids and bases or prolonged humidity at elevated temperature are present.

Common environments for this compound include construction machinery, hydraulic cylinders, and high-pressure fluid power.

Stocked as U90218 and sold individually. Nominal inside diameter is listed as 1 1/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
