The BAO product series is a single-acting piston seal featuring a FlexiSeal® design with a helicoil spring. It stands out due to extreme temperature and chemical resistance and is ideally suited for the medium pressure range. Due to its axially short length, the seal is particularly well suited for compact piston designs.
• Heavy dynamic lip (outside) 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 reciprocating piston sealing.
