HUNGER TDMA PISTON SEAL

    TDMA PISTON SEAL

    The HUNGER TDMA tandem seal for multi-fluid outside sealing application is used to seal pistons and plungers. It can be used with mineral oils and in modified form with compressed air.
    The TDMA seal consists of two parts, an elastic ring of PUR with 2 sealing lips and a slide ring of abrasionresistant PTFE-Bronze Compound with 2 sealing edges. Prior to fitting, the sealing lips protrude beyond the nominal diameter of the seal and are pressed against the cylinder wall after fitting. Thus effective sealing is provided even at zero pressure.
