568-464 URETHANE 70 DURO ORINGS

The U70464 is an AS568-464 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with an inside diameter of 17.455 in (443.36 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 18.005 in (457.33 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against ozone, extrusion under high pressure, and impact and shock loading. That behavior comes from the compound itself: Polyurethane (AU/EU) is specified for toughness that outperforms conventional rubber compounds and outstanding extrusion resistance at elevated pressure. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with prolonged humidity at elevated temperature or ketones.

Common environments for this compound include construction machinery, off-highway equipment, and hydraulic cylinders.

U70464 ships individually. Nominal inside diameter is listed as 17 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
