Product Overview
General CST2 Cold-Shot Pipe Freeze Kit
With a Cold-Shot, you don’t have to drain water lines, sprinkler systems, or hot water systems before cutting pipe or tubing. It keeps a fully pressurized system operating while you make repairs.
The Cold-Shot freezes liquids in steel, copper, cast iron, aluminum and plastic pipes ranging from 1/8" through 2" (10 to 60mm) using carbon dioxide (CO2). Dip tube-type CO2 cylinders are available from any welding supply house.
The Cold-Shot works faster than “refrigerator-type” units, is more compact and less expensive. It’s faster and uses less CO2 than “bag-type” pipe freezers, because the freeze head makes a better seal around the pipe. In five minutes you’re ready to go to work on 1/2" copper tubing, and just three minutes for cast iron pipe.
Includes:
10 sets of freeze heads for 1/8" 2" lines, two high pressure spiral hoses w/grips & injectors, T-Distributor, locking nut, hex head screwdriver, rubber gloves, goggles, and carrying case

The freezing times and CO2 requirements in the table below are general guidelines based on a water temperature 68 F° (20C°). These figures will vary for other temperatures. Longer freezing times are required for plastic pipe.
