In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Polyurethane (AU/EU) is widely chosen for outstanding extrusion resistance at elevated pressure and toughness that outperforms conventional rubber compounds. It resists petroleum oils, ozone, and extrusion under high pressure. Service temperature is rated from -65°F (-53.9°C) through 200°F (93.3°C).

Maintenance and OEM teams specify it across hydraulic cylinders, mining and heavy equipment, and high-pressure fluid power.
