568-928 URETHANE 90 ORINGS -PREM GRADE

The U90928 is an AS568-928 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 2.09 in (53.09 mm), a cross section of 0.118 in (3 mm), and an outside diameter of 2.326 in (59.08 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to petroleum oils, impact and shock loading, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) offers very high tensile strength and load capacity, exceptional abrasion resistance. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). It is not the right choice where hot water and steam or ketones are present.

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

Reference part number U90928 when ordering; the item is sold individually. 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.
