Arctic Hayes ‎ZEK2 Aero Disposable Pipe Freeze Kit with 2 Freezing Jackets for Plumbing Installation, Repair & Maintenance. Freezes Plastic & Metal Pipes (8-28mm Diameter), Blue

I wanted to remove 6 old TRV's (Thermostatic Radiator Valve) on radiators and fit new ones but that I didn't want to do was do them all in one go (I actually did one a day !), and I also didn't want to drain the whole system either... enter this great kit ! Please not one kit will do TWO radiators, so I needed 3 kits. First you should fully close the valve at the opposite end where the TRV valve is (usually has a small push on cover over it) then next fully close the old TRV... i.e. set to lowest setting (1)… then slacken the nut from the TRV nearest the radiator, thus allowing all the water to drain from the radiator - on my smallest radiator it took 2 dishes of water, so make sure you have a bucket or two to empty the water into (there will be more water than you think) and a couple of old towels in case of leakage ! Next it was time to use this brilliant kit... you first fasten the blue insulating sleeve around the pipe using the sliding fastener provided and then secure it 'very tightly' at the bottom to the pipe with the cable tie provided. Then you attach the little pipe to the aerosol and squirt the cold spray into the jacket pushing the nozzle into the inside of the jacket, next to the pipe. You need to keep topping it up a little at time until you have used half of the aerosol, and you then need to leave it about 5 minutes so the 'ice plug' form in the copper pipe. (Full instructions are included.. PLEASE READ THEM, this is just a quick summary !) After 5 minutes or so I slowly opened the TRV to maximum (6) to make sure no water came out (this shows the ice plug has formed, if you get water coming out, close the valve again (1) quickly and squirt more aerosol in... but I had no problem with any of my 6 valves) you can then remove the old TRV and in my case I used a professional pipe cutter which you put on the pipe and turn it one turn but you can use a hacksaw then file the top of the pipe smooth, it just takes longer and is more fiddly. After removing the old valve to can fit the new one, I made sure the new one was closed (once again, set to "1") and have the nut and olive to hand so you can fit it to the pipe straight away... don't forget all your tools too, so you don't have to go out to the shed for 10 minutes to find them, the plug could melt in that time, please, please, prepare ! The pipe should stay frozen for up to 20 minutes, but I managed to change each valve in 5-6 minutes max. When that is fitted, attach the other end of the valve to the radiator, remove the blue insulating coat by cutting the cable tie and removing the slider... open the valve at the other end of the radiator, then wait 10 minutes or so for the pipe to fully thaw out and check for leaks... bleed the radiator at the top, then you can fire up your central heating and once again check for leaks. This freezer kit is excellent and really saves you a lot of time and trouble draining the system, as you have to attach a long pipe to the lowest drain point of the system which then has to be run outside of the house to get rid of all the water. Trust me it is not fun and takes ages, then it takes ages to refill the system, this kit is SO much easier ! Hope this helps !

Our Cockstop tap was leaking and we couldn't find the outside manhole tap to close it. (Old building 1847) This worked exceptionally well. We just needed to freeze the one side of the pipe and replace the tap. It was very easy to use and I would use it again.

Nothing wrong with this product except the price, but it was the cheapest I could find at the time.

I have only used this on a vertival pipe. It froze a 15mm copper pipe quickly. I needed to replace a raiator valve. I have about 1/2 of the can left for another pipe if needed.

Does the trick, but left me a bit stranded. Bought to lower a radiator, so I needed to freeze both sides before cutting the pipes and refitting the valves. I bought a large pack, which is supposed to give you 2 freezes for 15mm copper. Instructions say "spray for 3 mins - half a can". The whole can was gone in a little over a minute (and it's not like you can see how much you're using, nor can you really get a sense of the weight change). It does work well, but then I was stuck and just had to drain down the system anyway to finish the job and do the other side before the ice melted. Therefore a bit of a waste of money. If you're doing similar, I'd just drain down.

Product did not work out the box following the instructions. You cant get a tight enough wrap with the cable ties when using the hard plastic sleeve clip as the instructions said as its not flexible. If you cut the sleeve clip to allow for the cable ties on the end the sleeve wont seal properly. You can wrap the ends in lots of tape to stem the flow, but by the time you have tested this there is not enough spray for the second pipe. Had to drain the system in the end due to the unreliability of this expensive product. It did not freeze the pipe to allow for removal. Would not recommend

I had to replace the washer on the cold water main entering my flat. This would normally mean closing off the supply to the building and inconveniencing the other five flats and up to twenty people living here or calling in a plumber with an electric freezing machine. Instead I used this stuff to seal off the stop cock valve so I could work on it and the job was done in half an hour. The pipe I froze was a 15mm copper water pipe, the instructions said that half a can would do it but I used the whole can as I was not going to risk it. Froze the pipe solid after a five minute wait, and it slowly started to thaw after 15 minutes which was plenty of time to replace the washer and clean the valve seat. Stop cock works perfectly now, this product made a tricky job simple. Brilliant.

I read reviews on this before buying and was a little apprehensive but had to do it anyway as i needed to cut pipes without draining the system. Some reviews said it didn't work. Bought the large can which does 2 pipes. The instructions did not clarify for how long you pressed the nozzle for on the 1st pipe. I was fearful of going for too long and not having enough for the second pipe. Cleverly I weighed the can. Took off the contents weight to work out the weight of the canister. Halved the weight of the contents and added this to the weigh of the canister. Then pressed on 1st application until the overall weight was down to half contents plus canister. Had to stop and weigh a couple of times. Once fully applied waited the 5 mins and then cut the pipe. Bingo! I was to, say politely, amazed to see there were no leaks. The ice plug worked well. Tip of the day. Put the alarm on your phone set for a few minutes before they say the ice plug will start melting.

Great product. Used it like it said how to and it worked perfectly. It never froze it for the full 30/ 40 minutes. But it did work for around 15 minutes. Enough for me to cut and replace a valve with a shark bite valve. Thanks again.

Used on 3/4 copper pipe to replace main water valve. Pipe get frozen after 8 min slowly sprayed. Almost whole can used. Because I have just 8 inches between jacket and pipe ice pops out when I screwed in new valve. But dangerous part was done already. Key point is ещ be prepared : sand pipe, get ready all the tools. Leave main valve open to allow water to expand. Close all toilets water, ice makers, air humidifiers, etc. Make sure there's not a single small water movement in the system - this is why so many negative feedback, thought.

I was doing a main service repair in a house. It froze the 3/4” copper line no problem as instructed. I cut the main line and to my horror realized I had bought the wrong size repair coupling when I tried to slip it on. While my guy raced to the plumbing supplier it still took him almost 30 min to get back and I was $&@?! My pants fully expecting the freezing to let go and flood this basement. We put on the new coupling and about 5 minutes later the water started flowing. This stuff worked amazingly!!! And I learned a valuable lesson. Triple check everything!!

Arctic Hayes ZEK2 Aero Pipe 2 Jacket Freeze Kit 8-28mm (.75-1") Dia. pipe. I bought this after my brother, a former plumber, told me about freeze plugging charged water pipes in order to make repairs. I needed to replace a stuck gate valve in my hydronics heating system, and had no way to completely vacate the line, nor did I want to. The pipe was a vertical 1" Type M non-rigid copper riser, so it was not a thick walled pipe and well within the parameters for using this product. After following the instructions "to the letter" I emptied the entire can of refrigerant as directed, and waited the 5-10 min. suggested for the refrigerant to take effect and create the ice plug... it didn't. And in fact it never even came close to creating the plug. It's not like the pipe had flowing or hot water in it, the line had been closed for several weeks. Nor was there any pressure in the line to dislodge the ice plug, the plug simply never formed. I would have to classify this product as a complete failure; hands-down, probably one of the biggest waste $55 that I've spent. Fortunately, I did not trust it from the get-go and purchased a SharkBite valve as the replacement just in case. Turned out to be a very wise decision since I had to very quickly install the closed valve while the pipe dumped water into a bucket. Bottom line; I feel this product is a complete farce that fails to live up to its promises. As such, I would not recommend it. I hope this review helps you in some way when considering similar projects. (As a side note; there are places you can rent professional CO2 freeze kits, but they are not cheap and take some skill to use them correctly, so it might serve you well to consult a licensed plumber first.)

doesn't work for me
