BUT
Design
    • Provides exceptional extrusion resistance to a paired oring to increase pressure handling capabilities.
    • Ideal in applications where low friction is a priority.
    • Can be used as a backup to a hydraulic seal or an oring.
    • PTFE will 'cold-flow' into an extrusion gap to provide superior extrusion resistance to Nitrile.
Material
    • PTFE
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
