568-356 URETHANE 90 ORINGS -PREM GRADE

This o-ring is supplied in AS568-356 clear Polyurethane (AU/EU) 90 Shore A measuring an inside diameter of 5.35 in (135.89 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.77 in (146.56 mm), catalogued under part number U90356. It delivers dependable bidirectional sealing in a compact groove envelope.

It resists ozone, extrusion under high pressure, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) is valued for very high tensile strength and load capacity, outstanding extrusion resistance at elevated pressure. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). It should not be specified for service in acids and bases or hot water and steam.

It sees regular use in high-pressure fluid power, press and forming equipment, and construction machinery.

This item is sold individually under part number U90356. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
