568-458 URETHANE 70 DURO ORINGS

APG stocks the U70458, an AS568-458 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 14.475 in (367.67 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 15.025 in (381.64 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Polyurethane (AU/EU) is specified here for long wear life in dynamic reciprocating service and toughness that outperforms conventional rubber compounds. The compound resists abrasion and wear, impact and shock loading, and ozone. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C).

You will find this material specified across construction machinery, hydraulic cylinders, and mining and heavy equipment.

Reference part number U70458 when ordering; the item is sold individually. Nominal inside diameter is listed as 14 1/2 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
