568-178 URETHANE 70 DURO ORINGS

This o-ring is supplied in AS568-178 clear Polyurethane (AU/EU) 70 Shore A measuring an inside diameter of 9.737 in (247.32 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 9.943 in (252.55 mm), catalogued under part number U70178. It delivers dependable bidirectional sealing in a compact groove envelope.

The compound resists impact and shock loading, petroleum oils, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) is valued for toughness that outperforms conventional rubber compounds and outstanding extrusion resistance at elevated pressure. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. Verify compatibility before use with prolonged humidity at elevated temperature or hot water and steam.

Typical settings include high-pressure fluid power, mining and heavy equipment, and hydraulic cylinders.

This item is sold individually under part number U70178. As always, verify media compatibility and operating conditions against the requirements of your specific application. 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.
