PU+PTFE - BRONZE/ CARBON/ MOS2/ GRAPHITE
Description & Advantages
The NS-95 TDMI tandem seal for multi-fluid inside 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 PUR with two sealing lips and an internal slide ring of abrasion resistant PTFE-Bronze compound. 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. The slide ring is surrounded by the elastic ring and moves axially in direct contact with the piston rod. With increasing pressed and compression of the sealing ring, it is slide ring which is predominantly pressed against the piston rod. The inner surface of the TDMI mainly comprises the slide ring which has excellent sliding properties.
