*568-220 URETHANE 90 ORINGS - PREM GRADE

Ordered as U90220, this is an AS568-220 clear Polyurethane (AU/EU) 90 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). The o-ring compresses into its gland to block fluid or gas migration across a joint.

Polyurethane (AU/EU) is widely chosen for toughness that outperforms conventional rubber compounds, very high tensile strength and load capacity. This material stands up to extrusion under high pressure, petroleum oils, and abrasion and wear. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Exposure to prolonged humidity at elevated temperature or hot water and steam will shorten service life.

You will find this material specified across hydraulic cylinders, off-highway equipment, and high-pressure fluid power.

U90220 ships individually. Nominal inside diameter is listed as 1 3/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
