568-237 URETHANE 70 DURO ORINGS

APG stocks the U70237, an AS568-237 clear Polyurethane (AU/EU) 70 Shore A O-Ring with an inside diameter of 3.359 in (85.32 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.637 in (92.38 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, Polyurethane (AU/EU) is known for very high tensile strength and load capacity, outstanding extrusion resistance at elevated pressure. It resists impact and shock loading, ozone, and extrusion under high pressure. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. It should not be specified for service in ketones or hot water and steam.

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

Stocked as U70237 and sold individually. Nominal inside diameter is listed as 3 3/8 inch. Check the compound against your process media, pressure and temperature before committing to a design.
