568-120 URETHANE 70 DURO ORINGS

APG stocks the U70120, an AS568-120 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 0.987 in (25.07 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.193 in (30.3 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to ozone, extrusion under high pressure, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) is valued for long wear life in dynamic reciprocating service, very high tensile strength and load capacity. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C).

Typical settings include press and forming equipment, off-highway equipment, and mining and heavy equipment.

Reference part number U70120 when ordering; the item is sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
