Wire Style Extensions are designed to keep the nozzle centered in the pipe.
Nozzle Extensions add a level of safety and effectiveness to your cleaning process. Extensions are added at the end of the sewer jetter hose and before the sewer cleaning nozzle. Extension is constructed Male * Female for easy attachment.
The additional length at the nozzle is used as an aid to help prevent the nozzle from entering a lateral from the mainline or "FLIPPING" and returning to the insertion point.
