568-309 URETHANE 90 ORINGS -PREM GRADE

Part number U90309 is an AS568-309 clear Polyurethane (AU/EU) 90 Shore A O-Ring with an inside diameter of 0.412 in (10.46 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 0.832 in (21.13 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Polyurethane (AU/EU) is specified for exceptional abrasion resistance and toughness that outperforms conventional rubber compounds. Expect good resistance to impact and shock loading, ozone, and petroleum oils. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). Applications involving prolonged humidity at elevated temperature or ketones call for a different compound.

Common environments for this compound include mining and heavy equipment, press and forming equipment, and off-highway equipment.

U90309 ships individually. Check the compound against your process media, pressure and temperature before committing to a design.
