The containment of the drag discs within the confined space of the hollow spindle allows significantly higher pressures to be applied to the discs than would otherwise have been possible with a drag located outside of the spindle.

This compression within a confined space derives maximum efficiency from the drag working surfaces which in turn allows us to use lubricated PTFE (Teflon) for a superbly smooth and consistent drag with low start up inertia.

There are three drag discs within the reel with a total of six working surface areas. It is worth noting that all drag components are individually machined to exact tolerances to ensure optimal performance.

If you are interested in the technical information, the drag discs are made of PTFE or Polytetrafluorethene. PTFE has the lowest coefficient of all known solid materials and as the static and dynamic coefficients are almost equal, "stick-slip" movement is almost eliminated. It is non-wetting and self-lubricating. PTFE has outstanding resistance to all chemicals and solvents due to the molecular stability of the carbon-fluorine bond. It has a wider working temperature than any other plastic. It can be used continuously at up to 250 degrees Celsius and at the other extreme, PTFE has been used successfully at the temperature of liquid helium (-269 degrees Celsius) without embrittlement. Teflon and Fluoron are registered trade names for PTFE.
