The Cold-Shot pipe freezing kit from General Pipe Cleaners lets professionals repair an operating water system – without draining lines, sprinkler or hot water systems before cutting pipe or tubing. It keeps a fully pressurized system operating while you repairs are made. Using carbon dioxide (CO2) in dip-tube cylinders, Cold-Shot freezes liquids in steel, copper cast iron, aluminum or plastic pipes – 1/8” through 2” in diameter – in minutes. Safe and easy to use, simply place the freeze head around the pipe, attach the hose, and open the CO2 cylinder valve. Liquid CO2 flows into the Cold-Shot freeze head, forming an ice pack in the line capable of withstanding 7000 psi.
