APG stocks the U70327, an AS568-327 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with an inside diameter of 1.725 in (43.82 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.145 in (54.48 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Polyurethane (AU/EU) is widely chosen for outstanding extrusion resistance at elevated pressure and toughness that outperforms conventional rubber compounds. This material stands up to ozone, extrusion under high pressure, and impact and shock loading. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with hot water and steam or ketones.

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