HUNGER ZSDI ROD SEAL

    ZSDI ROD SEAL

    The HUNGER ZSDI seal for cylinders with radial drillings is a piston rod seal which can dynamically operate over drillings in the cylinder bore up to 3 mm diameter. It can also be used as a high pressure seal on cylinders without radial drillings up to 2000 bar.

    The ZSDI seal consists of 5 parts. Two L-shaped metallic support rings and an intermediate metallic thrust
    ring support a slide ring of PTFE -Compound with narrow sealing lips on its inner diameter. An O-Ring acts as energiser to provide a sealing function even at zero pressure.
