568-170 URETHANE 90 ORINGS -PREM GRADE

The U90170 is an AS568-170 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 7.737 in (196.52 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 7.943 in (201.75 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Polyurethane (AU/EU) is widely chosen for exceptional abrasion resistance, very high tensile strength and load capacity. This material stands up to abrasion and wear, impact and shock loading, and petroleum oils. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C).

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

Order part number U90170, sold individually. Nominal inside diameter is listed as 7 3/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
