568-470 URETHANE 90 ORINGS -PREM GRADE

APG stocks the U90470, an AS568-470 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 20.955 in (532.26 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 21.505 in (546.23 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Polyurethane (AU/EU) is widely chosen for exceptional abrasion resistance and toughness that outperforms conventional rubber compounds. This material stands up to petroleum oils, impact and shock loading, and abrasion and wear. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C).

It sees regular use in high-pressure fluid power, construction machinery, and hydraulic cylinders.

U90470 ships individually. Check the compound against your process media, pressure and temperature before committing to a design.
