Product Specification

-
This o-ring is supplied in AS568-045 clear Polyurethane (AU/EU) 70 Shore A measuring an inside diameter of 3.989 in (101.32 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 4.129 in (104.88 mm), catalogued under part number U70045. It compresses into its gland to block fluid or gas migration across a joint.

As a material, Polyurethane (AU/EU) is valued for very high tensile strength and load capacity, outstanding extrusion resistance at elevated pressure. It resists impact and shock loading, abrasion and wear, and petroleum oils. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). It should not be specified for service in prolonged humidity at elevated temperature or ketones.

Maintenance and OEM teams specify it across mining and heavy equipment, press and forming equipment, and off-highway equipment.

Reference part number U70045 when ordering; the item is sold individually. Nominal inside diameter is listed as 4 inch. Check the compound against your process media, pressure and temperature before committing to a design.
