TDMI ROD SEAL
The HUNGER TDMI tandem seal for multi-fluid inside sealing applications, is used to seal piston rods and plungers. It can be used with mineral oils and in modified form with water base fluids, fire resistant fluids and compressed air.
The TDMI seal consists of two parts, an elastic ring of NBR and an internal slide ring as sealing ring. Prior to fitting, the sealing lips protrude beyond the nominal diameter of the seal and when fitted are pressed against the piston rod. Effective sealing is thereby provided even at zero pressure.
