568-328 URETHANE 70 DURO ORINGS

APG stocks the U70328, an AS568-328 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with an inside diameter of 1.85 in (46.99 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.27 in (57.66 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Polyurethane (AU/EU) is specified here for long wear life in dynamic reciprocating service, very high tensile strength and load capacity. It resists extrusion under high pressure, ozone, and impact and shock loading. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). It should not be specified for service in ketones or acids and bases.

It sees regular use in hydraulic cylinders, off-highway equipment, and high-pressure fluid power.

U70328 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
