568-203 URETHANE 70 DURO ORINGS

U70203 is an AS568-203 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 0.296 in (7.52 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.574 in (14.58 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Polyurethane (AU/EU) is specified here for toughness that outperforms conventional rubber compounds and outstanding extrusion resistance at elevated pressure. The compound resists petroleum oils, ozone, and abrasion and wear. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C).

It sees regular use in press and forming equipment, hydraulic cylinders, and mining and heavy equipment.
