568-220 URETHANE 70 DURO ORINGS

U70220 is an AS568-220 clear Polyurethane (AU/EU) 70 Shore A O-Ring with an inside diameter of 1.359 in (34.52 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 1.637 in (41.58 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to ozone, petroleum oils, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) is known for toughness that outperforms conventional rubber compounds and outstanding extrusion resistance at elevated pressure. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with prolonged humidity at elevated temperature or hot water and steam.

It sees regular use in high-pressure fluid power, hydraulic cylinders, and press and forming equipment.

Stocked as U70220 and sold individually. Nominal inside diameter is listed as 1 3/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
