This is our 6" Washout Skid for 3/8"" ID Hose (actual diameter 4.5" OD).  
 
The All-Skid Centralizer allows the operator to pick their nozzle, or other tooling, off the bottom of the pipe and center it for more efficient cleaning, milling, and prolonged tool life. Centralizing the tools on the inside of the pipe is crucial to a better overall job and creates a more efficient path to the full diameter recovery of 6” pipes.  When used in plastic pipes, other aggressive tooling not usually capable of being used in plastic, now becomes an option to the user.  This keeps these tools off the pipe wall; allowing the operator to further open their toolbox and solve problems different problems efficiently and effectively.  The unique shape is arrayed with 4 channels that allow for the passage of water and debris, while also keeping the tooling out of holes, and lowering the risk of getting hung up. 
 
This skid is offered in three variants. Red for 1/2" ID hose, Green for 3/8" ID hose, and Blue for 1/4" ID hose.
