This o-ring is supplied in AS568-409 clear Polyurethane (AU/EU) 70 Shore A supplied with an inside diameter of 2.475 in (62.87 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.025 in (76.84 mm), catalogued under part number U70409. It remains the most cost-effective sealing element available for pressurized assemblies.
Polyurethane (AU/EU) is widely chosen for very high tensile strength and load capacity, exceptional abrasion resistance. Expect good resistance to ozone, abrasion and wear, and impact and shock loading. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. Verify compatibility before use with acids and bases or ketones.
Common environments for this compound include high-pressure fluid power, mining and heavy equipment, and construction machinery.
Reference part number U70409 when ordering; the item is sold individually. Nominal inside diameter is listed as 2 1/2 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
