568-351 URETHANE 70 DURO ORINGS

Ordered as U70351, this is an AS568-351 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with an inside diameter of 4.725 in (120.02 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.145 in (130.68 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, Polyurethane (AU/EU) offers toughness that outperforms conventional rubber compounds and exceptional abrasion resistance. This material stands up to impact and shock loading, extrusion under high pressure, and ozone. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. Applications involving prolonged humidity at elevated temperature or ketones call for a different compound.

Common environments for this compound include high-pressure fluid power, hydraulic cylinders, and press and forming equipment.

Order part number U70351, sold individually. Nominal inside diameter is listed as 4 3/4 inch. Check the compound against your process media, pressure and temperature before committing to a design.
