CST-2 General Wire Cold-Shot Pipe Freeze Kit
No need to drain water lines, sprinkler systems, or hot water systems before cutting pipe or tubing. The Cold-Shot keeps pressurized systems operating while you make repairs. It freezes all type of liquids in steel, copper, cast iron, aluminum, and plastic pipes ranging from 1/8" to 2" (10 mm ? 60 mm) using carbon dioxide (CO2). Dip-tube type cylinders are available at all welding supply houses. The Cold-Shot is faster and less expensive than "refrigerator-type" units; faster and uses less CO2 than "bag-type"units. In five minutes you?re ready to go to work on copper tubing, just three minutes for cast iron pipe.
