568-437 URETHANE 70 DURO ORINGS

U70437 is an AS568-437 clear Polyurethane (AU/EU) 70 Shore A O-Ring with an inside diameter of 5.975 in (151.77 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 6.525 in (165.74 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists extrusion under high pressure, impact and shock loading, and ozone. Polyurethane (AU/EU) is widely chosen for toughness that outperforms conventional rubber compounds and exceptional abrasion resistance. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. Exposure to ketones or hot water and steam will shorten service life.

Maintenance and OEM teams specify it across off-highway equipment, mining and heavy equipment, and hydraulic cylinders.

Order part number U70437, sold individually. Nominal inside diameter is listed as 6 inch. Check the compound against your process media, pressure and temperature before committing to a design.
