568-348 URETHANE 70 DURO ORINGS

U70348 is an AS568-348 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with an inside diameter of 4.35 in (110.49 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.77 in (121.16 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 abrasion and wear. Polyurethane (AU/EU) delivers long wear life in dynamic reciprocating service and toughness that outperforms conventional rubber compounds. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Exposure to acids and bases or ketones will shorten service life.

Typical settings include construction machinery, hydraulic cylinders, and high-pressure fluid power.
