568-386 URETHANE 70 DURO ORINGS

Ordered as U70386, this is an AS568-386 clear Polyurethane (AU/EU) 70 Shore A O-Ring built to an inside diameter of 16.955 in (430.66 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 17.375 in (441.33 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Polyurethane (AU/EU) is valued for long wear life in dynamic reciprocating service and toughness that outperforms conventional rubber compounds. Expect good resistance to petroleum oils, impact and shock loading, and abrasion and wear. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Exposure to acids and bases or ketones will shorten service life.

It sees regular use in hydraulic cylinders, construction machinery, and press and forming equipment.
