*568-329 URETHANE 90 ORINGS - PREM GRADE

APG stocks the U90329, an AS568-329 clear Polyurethane (AU/EU) 90 Shore A O-Ring with an inside diameter of 1.975 in (50.17 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.395 in (60.83 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Polyurethane (AU/EU) is specified here for toughness that outperforms conventional rubber compounds and outstanding extrusion resistance at elevated pressure. The material holds up against abrasion and wear, petroleum oils, and extrusion under high pressure. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C).

Maintenance and OEM teams specify it across hydraulic cylinders, press and forming equipment, and construction machinery.

Reference part number U90329 when ordering; the item is sold individually. Nominal inside diameter is listed as 2 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
