This tool is necessary for swaging the ferrule. It includes a die for 1/8" cable.
The swager has a couple of features to make operation smooth and easy. A stabilizing foot keeps the tool upright when pumping. A lever on the valve handle makes turning the valve quick and easy. The open position of the die is optimized for minimum die travel when swaging. Springs keep the die fully open when inserting the ferrule for ease of loading the die.
