This o-ring is supplied in AS568-202 clear Polyurethane (AU/EU) 90 Shore A built to an inside diameter of 0.234 in (5.94 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.512 in (13 mm), catalogued under part number U90202. It creates a positive seal at flange, piston and rod interfaces without added hardware.
Polyurethane (AU/EU) delivers outstanding extrusion resistance at elevated pressure, very high tensile strength and load capacity. The material holds up against petroleum oils, impact and shock loading, and ozone. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. Exposure to hot water and steam or acids and bases will shorten service life.
You will find this material specified across mining and heavy equipment, high-pressure fluid power, and construction machinery.
Stocked as U90202 and sold individually. Nominal inside diameter is listed as 1/4 inch. Check the compound against your process media, pressure and temperature before committing to a design.
