568-410 URETHANE 90 ORINGS -PREM GRADE

U90410 is an AS568-410 clear Polyurethane (AU/EU) 90 Shore A O-Ring measuring an inside diameter of 2.6 in (66.04 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 3.15 in (80.01 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, Polyurethane (AU/EU) is widely chosen for toughness that outperforms conventional rubber compounds and outstanding extrusion resistance at elevated pressure. The compound resists extrusion under high pressure, ozone, and abrasion and wear. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C).

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

U90410 ships individually. Nominal inside diameter is listed as 2 5/8 inch. 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.
