568-342 URETHANE 70 DURO ORINGS

APG stocks the U70342, an AS568-342 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 3.6 in (91.44 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.02 in (102.11 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to ozone, impact and shock loading, and extrusion under high pressure. Polyurethane (AU/EU) delivers long wear life in dynamic reciprocating service and exceptional abrasion resistance. Rated temperature range runs from -65°F (-53.9°C) to 200°F (93.3°C) in continuous service. It should not be specified for service in acids and bases or prolonged humidity at elevated temperature.

Typical settings include mining and heavy equipment, hydraulic cylinders, and press and forming equipment.
