This o-ring is supplied in AS568-325 clear Polyurethane (AU/EU) 70 Shore A with an inside diameter of 1.475 in (37.47 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.895 in (48.13 mm), catalogued under part number U70325. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
As a material, Polyurethane (AU/EU) is known for toughness that outperforms conventional rubber compounds and exceptional abrasion resistance. The compound resists petroleum oils, 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 acids and bases or hot water and steam.
Maintenance and OEM teams specify it across mining and heavy equipment, construction machinery, and off-highway equipment.
Reference part number U70325 when ordering; the item is sold individually. Review your operating media and conditions against this specification before installation. 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.
