568-169 URETHANE 90 ORINGS -PREM GRADE

U90169 is an AS568-169 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 7.487 in (190.17 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.693 in (195.4 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Polyurethane (AU/EU) offers toughness that outperforms conventional rubber compounds and long wear life in dynamic reciprocating service. Expect good resistance to petroleum oils, extrusion under high pressure, and ozone. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Exposure to ketones or hot water and steam will shorten service life.

You will find this material specified across off-highway equipment, press and forming equipment, and mining and heavy equipment.

U90169 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
