The packed gland is used primarily for sealing process valve shafts (axial movement) and for process pump shafts (rotary movement).
The packed gland has provided a low tech, convenient solution throughout the history of engineering. In modern times the packed gland is being replaced by more exotic solutions.
Various materials are available dependant on the application.
Although we stock a wide variety of gland packing as a consumable product, we specialise in converting pumps to accommodate mechanical seals.
