General Wire Cold-Shot Pipe Freeze Kit.
CST-2 Cold-Shot pipe freeze kit includes: 10 sets of freeze heads for 1/8 to 2" lines, 2 high pressure spiral hoses with grips and injectors, T-distributor, locking nut, hex head screwdriver, rubber gloves, goggles and carring case.
The Cold-Shot freezes liquids in steel, copper, cast iron, aluminum and plastic pipes using carbon dioxide from dip tube type CO2 cylinders (not included). You no longer have to drain water lines, sprinkler systems or hot water systems before cutting pipe or tubing. It keeps the line fully pressuized while you make your repairs. Just place the freeze head around the pipe, attach the hose, and open the cylinder valve. Liquid carbon dioxide will flow into the freeze head and form dry ice with a temperature of -110 degrees F. Freezes 1/2"pipe in 3 minutes and copper in 5 minutes.
