568-343 URETHANE 90 ORINGS -PREM GRADE

This o-ring is supplied in AS568-343 clear Polyurethane (AU/EU) 90 Shore A supplied with an inside diameter of 3.725 in (94.62 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.145 in (105.28 mm), catalogued under part number U90343. It delivers dependable bidirectional sealing in a compact groove envelope.

It resists abrasion and wear, extrusion under high pressure, and impact and shock loading. Polyurethane (AU/EU) is specified for very high tensile strength and load capacity, long wear life in dynamic reciprocating service. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Exposure to prolonged humidity at elevated temperature or hot water and steam will shorten service life.

You will find this material specified across high-pressure fluid power, press and forming equipment, and construction machinery.

Reference part number U90343 when ordering; the item is sold individually. Nominal inside diameter is listed as 3 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
