PTFE Energized Seals for Static and Dynamic Applications

Energized PTFE seals offer extreme temperature, high pressure chemically inert static and dynamic sealking for the most demanding applications. Our thin flexible PTFE sealing jacket, made resilient by an internal energizing spring, applies a load to the sealing element at low pressures. As the system pressure increases enough to take over from the spring and engage the shaft or bore a highly efficient seal is created. The spring provides permanant resilience to the seal jacket and compensates for jacket wear, hardware misalignment or eccentricity.

    Factors Influencing Seal Performance
    Several factors effect seal performance and must be addressed in the design stage to ensure maximum reliability of Fluorolon seals.
    • Hardware Preparation: Surface Finish and Hardness
    • Spring Energizer
    • Polymer Jacket
    • Operating Conditions
    • Lubrication
    • Frictional Considerations
    • Spring Load vs Deflection
    • Extrusion Gap / Radial Clearance
