Ordered as U70146, this is an AS568-146 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with an inside diameter of 2.612 in (66.34 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.818 in (71.58 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
The material holds up against petroleum oils, extrusion under high pressure, and impact and shock loading. Polyurethane (AU/EU) is known for long wear life in dynamic reciprocating service, very high tensile strength and load capacity. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Exposure to ketones or hot water and steam will shorten service life.
Common environments for this compound include hydraulic cylinders, construction machinery, and mining and heavy equipment.
Reference part number U70146 when ordering; the item is sold individually. Nominal inside diameter is listed as 2 5/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
