568-132 URETHANE 70 DURO ORINGS

The U70132 is an AS568-132 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 1.737 in (44.12 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.943 in (49.35 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

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

Common environments for this compound include high-pressure fluid power, off-highway equipment, and hydraulic cylinders.
