568-339 URETHANE 70 DURO ORINGS

Part number U70339 is an AS568-339 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 3.225 in (81.92 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.645 in (92.58 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

Polyurethane (AU/EU) offers long wear life in dynamic reciprocating service and exceptional abrasion resistance. Expect good resistance to petroleum oils, impact and shock loading, and abrasion and wear. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C). Verify compatibility before use with prolonged humidity at elevated temperature or hot water and steam.

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

U70339 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
