Ordered as U70361, this is an AS568-361 clear Polyurethane (AU/EU) 70 Shore A O-Ring built to an inside diameter of 5.975 in (151.77 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.395 in (162.43 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.
Expect good resistance to ozone, petroleum oils, and impact and shock loading. Polyurethane (AU/EU) is specified 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. Applications involving acids and bases or hot water and steam call for a different compound.
It sees regular use in hydraulic cylinders, high-pressure fluid power, and construction machinery.
Reference part number U70361 when ordering; the item is sold individually. Nominal inside diameter is listed as 6 inch. 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.
