The Vitow Freeze-It 300ml Pipe Freeze Spray Kit is a specialized product designed for freezing water or other liquids within pipes to enable repair or maintenance work without draining the entire system. It temporarily freezes the liquid in the pipe, creating an ice block, which allows professionals to work on the pipe (such as cutting, soldering, or replacing sections) while minimizing the need for water to be turned off or the pipe to be drained.

This kit typically comes with the following components:

• Freeze-It Spray: The chemical solution in the can that, when sprayed, rapidly cools the pipe to freeze the water inside.
• Two Pipe Jackets: The jacket is to be fitted securely to the pipe and the the freeze spray is sprayed into the jacket to freeze the pipe.

It is commonly used by plumbers and HVAC professionals for tasks like:

• Pipe repairs without needing to shut down the entire water supply.
• Installation of valves or fittings when draining the system is not feasible.

In general, the product is a useful tool for creating temporary ice plugs in pipes to isolate sections without interrupting the flow of water or other fluids throughout the system.
