568-125 URETHANE 70 DURO ORINGS

APG stocks the U70125, an AS568-125 clear Polyurethane (AU/EU) 70 Shore A O-Ring supplied with 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). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Polyurethane (AU/EU) is specified here for very high tensile strength and load capacity, toughness that outperforms conventional rubber compounds. Expect good resistance to abrasion and wear, extrusion under high pressure, and impact and shock loading. The material carries a published service range of -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with prolonged humidity at elevated temperature or ketones.

Common environments for this compound include mining and heavy equipment, off-highway equipment, and hydraulic cylinders.

U70125 ships individually. Nominal inside diameter is listed as 1 5/16 inch. Check the compound against your process media, pressure and temperature before committing to a design.
