*568-329 URETHANE 70 DURO ORINGS

Part number U70329 is an AS568-329 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 1.975 in (50.17 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.395 in (60.83 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to impact and shock loading, abrasion and wear, and petroleum oils. That behavior comes from the compound itself: Polyurethane (AU/EU) is valued for very high tensile strength and load capacity, toughness that outperforms conventional rubber compounds. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). It is not the right choice where acids and bases or hot water and steam are present.

You will find this material specified across off-highway equipment, high-pressure fluid power, and construction machinery.
