*568-125 URETHANE 90 ORINGS -PREM GRADE

Ordered as U90125, this is an AS568-125 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 1.299 in (32.99 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.505 in (38.23 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Polyurethane (AU/EU) offers toughness that outperforms conventional rubber compounds and long wear life in dynamic reciprocating service. This material stands up to impact and shock loading, extrusion under high pressure, and petroleum oils. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). It is not the right choice where prolonged humidity at elevated temperature or ketones are present.

Common environments for this compound include high-pressure fluid power, hydraulic cylinders, and off-highway equipment.

Order part number U90125, sold individually. Nominal inside diameter is listed as 1 5/16 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.
