568-143 URETHANE 70 DURO ORINGS

The U70143 is an AS568-143 clear Polyurethane (AU/EU) 70 Shore A O-Ring with an inside diameter of 2.425 in (61.6 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.631 in (66.83 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against ozone, impact and shock loading, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) is valued for 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 sees regular use in off-highway equipment, high-pressure fluid power, and construction machinery.

This item is sold individually under part number U70143. Nominal inside diameter is listed as 2 7/16 inch. Review your operating media and conditions against this specification before installation.
