Compressed Gas Duster Freezing Spray 750ml - Set of 4 - Deep Freeze Spray, Freezer Spray, Pipe Freeze Spray, Frost Spray, Pipe Freezing Kit, Freezes Down to -50*C

Used almost all of a 750ml can with a jacket on a cold radiator pipe. Didn't work for me. Tried topping it up after a few minutes, still didn't work.When I removed the jacket, it wasn't even cool, no ice at all.Needless to say, it's not on my 'buy it again' list.

I used this to freeze 8mm pipe (with jacket and clips) so I could add a stop end. I tested it out first on spare pipe which stayed frozen over 20 minutes. 8mm pipe was at bottom of full central heating system at 1 bar. No leaks during the job. Plenty left for next time. For 15mm I would test it first on spare pipe. Advantage of this is that the regular plumbing spray is over £10 for 150ml. The disadvantage is that you have to have the can inverted for freezer. The pipe I was working on was along ceiling so I needed to extend the tube coming from the spray can. Fortunately I already had some flexible plastic tubing I could use.

Works fine freezing pipes. Just need a good sealed jacket and invert the can.

Cheap , good for testing thermostats on electrical circuits 👍

2nd purchase perfect for freeze and air very powerful too

So far I've used this item as freezer spray to locate thermal faults on several items of audio equipment with good success. I bought the big can and still have lots left. However, I could do with fabricating a trigger to hold the can upside down because after a while it becomes a bit uncomfortable for my wrist. Overall it worked great for me. I thoroughly recommend this product.
