568-358 URETHANE 70 DURO ORINGS

U70358 is an AS568-358 clear Polyurethane (AU/EU) 70 Shore A O-Ring with an inside diameter of 5.6 in (142.24 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.02 in (152.91 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Polyurethane (AU/EU) is widely chosen for toughness that outperforms conventional rubber compounds and long wear life in dynamic reciprocating service. The compound resists ozone, petroleum oils, and abrasion and wear. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Exposure to ketones or prolonged humidity at elevated temperature will shorten service life.

Common environments for this compound include hydraulic cylinders, press and forming equipment, and mining and heavy equipment.

U70358 ships individually. Check the compound against your process media, pressure and temperature before committing to a design.
