Product Specification

-
This o-ring is supplied in AS568-423 clear Polyurethane (AU/EU) 70 Shore A supplied with an inside diameter of 4.225 in (107.32 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 4.775 in (121.29 mm), catalogued under part number U70423. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Polyurethane (AU/EU) is specified here for very high tensile strength and load capacity, toughness that outperforms conventional rubber compounds. The compound resists impact and shock loading, ozone, and abrasion and wear. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with prolonged humidity at elevated temperature or ketones.

Maintenance and OEM teams specify it across hydraulic cylinders, off-highway equipment, and high-pressure fluid power.

Stocked as U70423 and sold individually. Check the compound against your process media, pressure and temperature before committing to a design.
