This o-ring compresses into its gland to block fluid or gas migration across a joint.
Polyurethane (AU/EU) delivers outstanding extrusion resistance at elevated pressure and exceptional abrasion resistance. It resists petroleum oils, impact and shock loading, and extrusion under high pressure. Continuous operating temperature is published at -65°F (-53.9°C) to 200°F (93.3°C). It is not the right choice where hot water and steam or prolonged humidity at elevated temperature are present.
Maintenance and OEM teams specify it across press and forming equipment, mining and heavy equipment, and hydraulic cylinders.
Order part number U70443, sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
