Product Overview
Description
    The BAI product series is a single-acting rod seal featuring a FlexiSeal® design with a helicoil spring. It is characterized by extremely high temperature and chemical resistance and ideally suited for use in the medium pressure range. Due to its short axial length, the seal is particularly well suited for installation in compact grooves.

    • Heavy dynamic lip (inside) ensures longest life.
    • Short, wiper-type dynamic lip reduces frictional forces due to hydrostatic pressure.
    • Helical spring for high load and small deflection range.
    • Squared, long static lip stabilizes the seal.
    • Widest range of cross-sections and diameters available, including sizes for upgrading standard O-ring grooves.
    • Many high-resilience energizer options available, including choice of light, medium and heavy loads and NACE for oil field use.
    • Low-cost elastomeric energizers available, all with excellent fatigue resistance.

    Range of application:
    For sealing reciprocating rods

    The BAI rod seal is available in the following compounds:
    001 - Industrial applications
    005 - High temperatures
    006 - Heavy-duty
