HUNGER RDA ROTARY SEAL

    RDA ROTARY SEAL

    The RDA rotary seal can be used as a sealing element for rotating machine parts. It is mainly
    used in rotary feed units for separation of oil or other fluids at different pressures and can be subjected to
    pressure on both sides. Since the seal requires only a small installation space, the external dimensions of
    rotary feed units can be kept to a minimum.
