TDT ROD SEAL
The HUNGER tandem seal type TDT is designed for use with telescopic cylinders. It can be used with mineral oils or compressed air.
The TDT seal is manufactured in PUR and has two sealing lips on the inside. Prior to fitting, these lips protrude beyond the nominal diameter of the seal. Following installation, seal compression forces the lips against the telescopic cylinder stages, thereby providing a sealing function at zero pressure.
