568-463 URETHANE 90 ORINGS -PREM GRADE

Part number U90463 is an AS568-463 clear Polyurethane (AU/EU) 90 Shore A O-Ring supplied with an inside diameter of 16.955 in (430.66 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 17.505 in (444.63 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Polyurethane (AU/EU) delivers exceptional abrasion resistance and long wear life in dynamic reciprocating service. It resists extrusion under high pressure, ozone, and petroleum oils. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Applications involving hot water and steam or ketones call for a different compound.

Typical settings include high-pressure fluid power, hydraulic cylinders, and mining and heavy equipment.

U90463 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
