568-441 URETHANE 70 DURO ORINGS

This o-ring is supplied in AS568-441 clear Polyurethane (AU/EU) 70 Shore A with an inside diameter of 6.975 in (177.17 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 7.525 in (191.14 mm), catalogued under part number U70441. It delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against petroleum oils, extrusion under high pressure, and impact and shock loading. That behavior comes from the compound itself: Polyurethane (AU/EU) delivers exceptional abrasion resistance and toughness that outperforms conventional rubber compounds. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Applications involving prolonged humidity at elevated temperature or hot water and steam call for a different compound.

Maintenance and OEM teams specify it across press and forming equipment, construction machinery, and mining and heavy equipment.

Stocked as U70441 and sold individually. Nominal inside diameter is listed as 7 inch. Check the compound against your process media, pressure and temperature before committing to a design.
