568-392 URETHANE 70 DURO ORINGS

APG stocks the U70392, an AS568-392 clear Polyurethane (AU/EU) 70 Shore A O-Ring built to an inside diameter of 22.94 in (582.68 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 23.36 in (593.34 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists ozone, petroleum oils, and abrasion and wear. Polyurethane (AU/EU) is widely chosen for long wear life in dynamic reciprocating service and exceptional abrasion resistance. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). It is not the right choice where ketones or hot water and steam are present.

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

Order part number U70392, sold individually. Nominal inside diameter is listed as 23 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
