Auxiliary Sealing System

The new TEADIT® ECO-SEAL Sealing System adds new benefits to the traditional Compression Packing Sets by increasing the performance of the packings, reducing the cost of the system and preservation of the environment. The ECO-SEAL can be used in a large variety of rotary equipment such as: Pumps, concrete mixers, reactors, etc. It is highly recommended for abrasive fluids and aggressive chemicals.Developed to work in the conventional stuffing box with compression packings, the ECO-SEAL is comprised of four rings of PTFE made from special polymers that exhibit a very low coefficient of friction, thereby creating a barrier between the process flow and the environment.


  • Because it does not allow the entry of abrasive particles into the packing contained within the stuffing box, it increases the useful life of all the components within the packed gland (packing rings, sleeve and stuffing box), thereby reducing the number of maintenance events.
  • Avoids contamination of the environment by reducing the amount of fluid migrating back through the stuffing box.
  • You will need less gland adjustments (re-torque), this will assist in reducing the stress induced by the friction between the Sleeve or shaft and the packing rings. This will cause a reduction in the consumption of energy.
  • It will reduce the consumption of the flush water required, as it does not allow stuffing box leakage back into the process. This eliminates process contamination and dilution of the process.
  • Can work with or without flush water and will operate without leakage*.
  • *in this case we recommend to use the packing style 2202 with carbon fiber/flexible graphite.

All of these benefits are due to the expansion of the sealing rings that takes place during the compression of the device. The expansion promotes an effective seal at the bottom of the stuffing box by eliminating the ability of Process Fluids to enter the stuffing box. This protects the packing and the process.
