568-347 URETHANE 90 ORINGS -PREM GRADE

Part number U90347 is an AS568-347 clear Polyurethane (AU/EU) 90 Shore A O-Ring built to an inside diameter of 4.225 in (107.32 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.645 in (117.98 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

As a material, Polyurethane (AU/EU) is known for outstanding extrusion resistance at elevated pressure and long wear life in dynamic reciprocating service. This material stands up to impact and shock loading, extrusion under high pressure, and abrasion and wear. 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 ketones.

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

Order part number U90347, sold individually. Nominal inside diameter is listed as 4 1/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
