568-370 URETHANE 90 ORINGS -PREM GRADE

Ordered as U90370, this is an AS568-370 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 8.225 in (208.92 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 8.645 in (219.58 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against impact and shock loading, extrusion under high pressure, and ozone. That behavior comes from the compound itself: Polyurethane (AU/EU) is widely chosen for exceptional abrasion resistance and outstanding extrusion resistance at elevated pressure. Published continuous service range is -65°F (-53.9°C) to 200°F (93.3°C). Verify compatibility before use with hot water and steam or acids and bases.

Common environments for this compound include press and forming equipment, high-pressure fluid power, and off-highway equipment.

Reference part number U90370 when ordering; the item is sold individually. Nominal inside diameter is listed as 8 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
