568-413 URETHANE 90 ORINGS -PREM GRADE

The U90413 is an AS568-413 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 2.975 in (75.57 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.525 in (89.54 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

Polyurethane (AU/EU) is specified here for outstanding extrusion resistance at elevated pressure and toughness that outperforms conventional rubber compounds. It resists extrusion under high pressure, impact and shock loading, and abrasion and wear. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Applications involving prolonged humidity at elevated temperature or acids and bases call for a different compound.

It sees regular use in construction machinery, mining and heavy equipment, and hydraulic cylinders.

This item is sold individually under part number U90413. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
