General Pipe Cleaners’ Cold-Shot pipe freezing kit lets users repair an operating water system without draining water lines, sprinkler systems or hot water systems before cutting pipe or tubing. Using carbon dioxide in dip-tube cylinders, it freezes liquids in steel, copper, cast iron, aluminum or plastic pipe 1/8” through 2” in diameter. It can create an ice plug in copper tubing within five minutes and in steel pipe within three minutes. The kit includes 10 sets of freeze heads, two high-pressure spiral hoses with injectors, rubber gloves, goggles and a carrying case.
