Product Specification

-
This o-ring is supplied in AS568-156 clear Polyurethane (AU/EU) 70 Shore A supplied with an inside diameter of 4.237 in (107.62 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 4.443 in (112.85 mm), catalogued under part number U70156. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists petroleum oils, ozone, and extrusion under high pressure. Polyurethane (AU/EU) is known for exceptional abrasion resistance, very high tensile strength and load capacity. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with acids and bases or hot water and steam.

Typical settings include press and forming equipment, mining and heavy equipment, and hydraulic cylinders.
