Pipe freezing kit
The Cold-Shot pipe freezing kit from General Pipe Cleaners repairs operating water systems without having to drain lines, sprinkler arrays, or hot water systems before cutting pipe or tubing. The Cold-Shot freezes liquids in steel, copper, cast iron, aluminum, or plastic pipes between 1/8-in. and two-inches in diameter using CO2 in dip-tube cylinders. The lightweight device distributes CO2 evenly around the pipe.
