BUP
Design
    • Provides exceptional extrusion resistance to a paired oring or seal to increase pressure handling capabilities.
    • High abrasion resistance makes it suitable in contaminated fluids.
    • Can be used as a backup to a hydraulic seal or an oring.
Material
    • 95A Polyurethane.
Application
    • Suitable for static and dynamic applications.
    • Suitable for high pressure and heavy duty applications where additional resistance to extrusion is required.
Fluids
    • Hydraulic fluids, petroleum fuels and oils
