The Cold-Shot kit at work.
The Cold-Shot Pipe Freezing Kit from General Pipe Cleaners allows homeowners to repair an operating water system – without draining lines, sprinkler arrays, or hot water systems before cutting pipe or tubing.
Using Carbon Dioxide (CO2) in dip-tube cylinders, the Cold-Shot freezes liquids in steel, copper, cast iron, aluminum, or plastic pipes – 1/8” through 2” in diameter – in minutes.
Here's how it works: 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.
Faster, more compact, and less expensive than “refrigerator-type” units, the Cold-Shot can create an ice plug in copper tubing within five minutes – and in steel pipe within three minutes. And unlike slower, less economic “bag-type” devices, General’s lightweight device provides a much better seal – and distributes CO2 evenly around the pipe.
The Cold-Shot kit includes 10 sets of freeze heads, two high pressure spiral hoses with grips and injectors, T-distributor, locking nut, hex head screw driver, rubber gloves, goggles, and carrying case.
