568-259 URETHANE 70 DURO ORINGS

Ordered as U70259, this is an AS568-259 clear Polyurethane (AU/EU) 70 Shore A O-Ring measuring an inside diameter of 6.234 in (158.34 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 6.512 in (165.4 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Polyurethane (AU/EU) is known for exceptional abrasion resistance and long wear life in dynamic reciprocating service. The material holds up against ozone, petroleum oils, and extrusion under high pressure. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Exposure to hot water and steam or ketones will shorten service life.

It sees regular use in press and forming equipment, off-highway equipment, and mining and heavy equipment.
