568-472 URETHANE 90 ORINGS -PREM GRADE

APG stocks the U90472, an AS568-472 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 22.94 in (582.68 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 23.49 in (596.65 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Polyurethane (AU/EU) is specified here for toughness that outperforms conventional rubber compounds and exceptional abrasion resistance. This material stands up to extrusion under high pressure, ozone, and abrasion and wear. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). It is not the right choice where ketones or prolonged humidity at elevated temperature are present.

Maintenance and OEM teams specify it across hydraulic cylinders, press and forming equipment, and mining and heavy equipment.

Reference part number U90472 when ordering; the item is sold individually. Nominal inside diameter is listed as 23 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
