568-446 URETHANE 70 DURO ORINGS

The U70446 is an AS568-446 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 8.475 in (215.27 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 9.025 in (229.24 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Polyurethane (AU/EU) is known for outstanding extrusion resistance at elevated pressure and exceptional abrasion resistance. The compound resists abrasion and wear, ozone, and petroleum oils. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Exposure to ketones or acids and bases will shorten service life.

Typical settings include construction machinery, mining and heavy equipment, and hydraulic cylinders.

U70446 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
