568-424 URETHANE 70 DURO ORINGS

APG stocks the U70424, an AS568-424 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 4.35 in (110.49 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.9 in (124.46 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to ozone, abrasion and wear, and impact and shock loading. That behavior comes from the compound itself: Polyurethane (AU/EU) delivers very high tensile strength and load capacity, outstanding extrusion resistance at elevated pressure. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C).

Maintenance and OEM teams specify it across off-highway equipment, construction machinery, and hydraulic cylinders.

Stocked as U70424 and sold individually. Nominal inside diameter is listed as 4 3/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
