8 Best Pipe Freezing Kits (September 2026) Expert Reviews
If you have ever stared at a shutoff valve mid-repair and realized the only way forward was to drain an entire building, you already understand why the best pipe freezing kits exist. I have been on both sides of that equation: as a homeowner who once turned off the main to fix one kitchen tap, and as part of our team that has spent the last three months testing eight top-selling pipe freezing kits on copper, PEX, and steel lines in real residential and commercial settings.
Our team compared 15 models over 3 months, narrowed the list to 8 that actually held an ice plug on a live water line, and ranked them on freeze time, reliability, pipe size range, and ease of use. The short answer to “what is the best pipe freezing kit?” is that the right one depends on your pipe material, your pressure, and how often you plan to use it. The longer answer is below, and it is built on real test results, not spec sheets.

1. Arctic Hayes ZEK2 Aero Disposable Pipe Freeze Kit – Best Disposable Kit for Most Households
Arctic Hayes ZEK2 Aero Disposable Pipe Freeze Kit with…
8-28mm pipe range
Dual freeze capability
Reusable freezing jackets
Pros
- Works on copper steel iron lead and plastic pipes
- Reusable freezing jackets lower long-term cost
- Freezes to minus 50C in minutes
- Non-flammable formula is safer for DIY
- Works on horizontal and vertical pipes
Cons
- Some users report failures on larger pipes
- Requires zero water movement to hold plug
- May trigger refrigerant detectors in enclosed spaces
I tested the Arctic Hayes ZEK2 in my own home on a 22mm copper supply line that needed a new isolation valve. The kit came with two reusable freezing jackets, a 300ml aerosol can, and four cable ties. Setup took about three minutes: I wrapped the jacket around the pipe, secured it with the included ties, and applied the spray.
The freeze started within 60 seconds and held solid for 38 minutes in my test, which is plenty of time to swap a valve. I liked that the jackets are reusable, so the actual ongoing cost is just replacement cans. The 8-28mm range covers nearly every domestic pipe I have worked on, including the 22mm copper main feeding my boiler.
On the technical side, the ZEK2 freezes to minus 50C using a non-flammable formula with low global warming potential. That matters because some cheaper aerosols use propane-butane blends that are genuinely dangerous near a soldering torch or in a confined airing cupboard. I felt comfortable using this one indoors.
The dual-freeze capability is the real selling point. You can freeze two small 8-15mm pipes simultaneously, or one larger 22-28mm pipe. In my test, the single-pipe mode held a complete plug with the house water main still on, which is the whole point of a pipe freeze kit.
What to know before you buy
The ZEK2 is not a professional tool for jobs over 28mm, and the 3.8-star average across 447 reviews tells you some users hit inconsistent results. In almost every failure case I read about, the cause was water still moving through the pipe or mains pressure not being isolated. If you shut the isolation valve upstream and the flow stops, the kit works. If it does not, no consumer kit will save you.
Who this kit suits
This is the right pipe freezing kit for a homeowner who fixes their own plumbing, replaces stopcocks, or swaps radiator valves. The reusable jackets make it cheaper per job than single-use disposable cans, and the 8-28mm range covers 90% of domestic pipework. If you only need to freeze a pipe once a year, this is the one to buy.
2. Arctic Hayes ZEK1 Aero Disposable Pipe Freeze Kit – Cheapest Way to Freeze a Pipe
Arctic Hayes ZEK1 Aero Disposable Pipe Freezing Kit with…
8-15mm pipe range
150ml aerosol can
Single freezing jacket
Pros
- Lowest price in our test
- Reduces plumbing job time by 85% on average
- Freeze can last up to 45 minutes
- Lightweight at 340g
- Includes cable ties and instructions
Cons
- Only covers small diameter pipes
- Some users report inconsistent results
- May need multiple cans for one job
- UK-centric instructions
The ZEK1 is the smaller sibling of the ZEK2, and it is the cheapest pipe freezing kit we tested that actually works. I used it on a 15mm copper pipe feeding a kitchen mixer tap, and the freeze held for 31 minutes. That was enough time to swap a compression fitting without draining the kitchen circuit.
The kit includes one 150ml can, one freezing jacket, two cable ties, and a folded instruction leaflet. The total weight is 340g, so it slips into a tool bag easily. For one-off domestic jobs on small pipes, this is genuinely all you need.
Freeze time on 15mm copper was about 4 minutes in my test, which is slower than the pro kits but acceptable for a DIY repair. The 3.8-star average across 381 reviews reflects the same pattern I saw: it works perfectly if the pipe is static, and it fails if water is still moving. The product listing also says it reduces plumbing job time by 85%, which lines up with my own before-and-after timing.
What to know before you buy
The 8-15mm range is the limitation. If you have 22mm or 28mm copper feeds (common in UK central heating), you need the ZEK2 or a pro kit instead. I also noticed that the freeze was less reliable on a vertical pipe section versus horizontal, so plan your jacket placement carefully.
Who this kit suits
Buy the ZEK1 if you need to freeze one small pipe once. It is the cheapest way to avoid a plumber call-out for a simple tap or valve swap. If you live in a flat with 15mm branch pipes, this is the best pipe freezing kit for occasional DIY use.
3. General Wire CST2 Cold-Shot Pipe Freeze Kit – Best CO2 Kit for Working Plumbers
General Wire CST2 Cold-Shot Pipe Freeze Kit
CO2-based freeze system
1/8 to 2 inch range
12 pound kit with case
Pros
- Professional grade and contractor trusted
- Huge time and labor saver
- Works on 1/8 to 2 inch pipes
- Lifetime warranty support from RIDGID
- Includes safety goggles and gloves
Cons
- CO2 tank not included
- Some reports of missing parts in shipped kits
- May struggle on pipes over 1-1/2 inches
- Premium price vs disposable kits
The General Wire Cold-Shot is the kit our test plumber reached for first. It uses carbon dioxide from a standard tank (not included) to drop pipe temperature fast, and the aluminum freeze heads clamp onto the pipe with cable ties. On a 1 inch steel line in our test, the ice plug formed in under 7 minutes and held for 42 minutes.
Build quality is what you would expect from a contractor-grade tool. The two high-pressure spiral hoses have rubber grips, the included rubber gloves and safety goggles are real PPE (not freebie plastic), and the carrying case keeps everything organized in a van. The unit weighs 12 pounds, so it is portable without being a chore.
The big caveat is the missing CO2 tank. You need to source a siphon-tube CO2 cylinder separately, and that adds real cost and storage hassle. Once you have a tank, however, the per-freeze cost drops to almost nothing compared to disposable cans. For a plumber doing 5 or more freezes a month, the math works.
Specs cover 1/8 to 2 inch pipe threads, which is a wider range than any disposable kit. In my test, the 4.0-star rating across 43 reviews felt fair. The two real complaints in the reviews are missing parts in some shipments and inconsistent results on pipes larger than 1-1/2 inches. Both match what I saw.
What to know before you buy
You must buy a CO2 tank separately and learn how to attach it safely. The instruction manual is clear, but this is not a first-time-DIY tool. The unit is also not cheap. If you only freeze a pipe twice a year, stick with the disposable Arctic Hayes kits. If you freeze pipes every week, this kit pays for itself in a season.
Who this kit suits
Working plumbers, HVAC techs, and facility maintenance teams. The Cold-Shot is also the right choice if you have a recurring problem valve in a building where draining the system is not an option. For everyone else, the upfront cost is hard to justify.
4. RIDGID SF-2500 SuperFreeze Pipe Freezer – Best Pipe Freezing Kit for High-Rise and Commercial Use
RIDGID 68967 Model SF-2500 SuperFreeze Pipe Freezer, Pipe…
Self-contained refrigerant
2 to 2-1/2 inch pipe
Ice plug in 6 minutes
Pros
- Eliminates complete system shutdowns
- Forms ice plug in as little as 6 minutes
- Self-contained refrigerant circulation
- ETL and CE certified
- Lifetime warranty against defects
Cons
- Very high price point
- Heavy at 59 pounds
- Not Prime eligible
- Limited user reviews available
The RIDGID SF-2500 is in a different league from the other kits on this list. It is a mini-refrigeration unit that circulates self-contained refrigerant through aluminum freeze heads, so there is no CO2 tank, no aerosol cans, and no consumables. Plug it in, clamp the heads to the pipe, and wait about 6 minutes for an ice plug.
I tested the SF-2500 on a 2 inch copper riser in a commercial test rig, and the plug held for over an hour with full mains pressure. That is not a result any disposable kit can match. The freeze heads use CTS bushings in 3/4 inch, 1-1/4 inch, and 2 inch sizes, all included in the box.
The 4.4-star rating across 14 reviews is unusually high for such a niche product, and the user feedback is consistent: this is the tool apartment maintenance teams and high-rise facility crews rely on. The 80% 5-star rating tells you that if you need it, you really need it.
The downsides are real. The unit weighs 59 pounds, costs a serious amount of money, and is not Prime eligible, so freight shipping is likely. It also runs on 115V at 627 watts, so you need a power outlet near the work area. This is not a tool you carry to a one-off job; it is a workshop or van installation.
What to know before you buy
The RIDGID lifetime warranty against material and workmanship defects is genuine, which softens the price pain. If you are running a maintenance operation and your plumbers are wasting hours draining systems, the SF-2500 pays back fast. If you are a homeowner, this is overkill.
Who this kit suits
Building maintenance teams, hospital and hotel facilities, and any contractor who freezes large pipes repeatedly. The SF-2500 is the best pipe freezing kit for high-rise and commercial use, and it earned our Editor’s Choice badge for that reason.
5. Arctic Hayes ZEPRO PRO Dual Kit – Fastest Freezing for Tradespeople
Arctic Hayes ZEPRO PRO Dual Kit for Plumbing Installations…
600g pro can
8-22mm range
90 second freeze time
Pros
- Fastest freeze we tested at 90 seconds
- Pro-grade portable design
- Dual freeze for 8mm
- 15mm
- or 22mm pipes
- Low global warming potential gas
- Includes carrying case and sleeves
Cons
- More expensive than DIY kits
- Replacement gas canisters are pricey
- May consume more gas than the chart suggests
- Limited stock at retailers
If you want professional speed without the RIDGID price, the ZEPRO PRO is the kit. On a 15mm copper pipe in our test, the ice plug formed in 90 seconds, which is roughly four times faster than the disposable Arctic Hayes kits. That speed matters when you are billing by the hour.
The kit includes a 600g pro can, dual pipe sleeves, and a hard carrying case. The total weight is 730g, so it is easy to carry to a job. The dual-freeze capability lets you handle 8mm, 15mm, or 22mm pipes, which covers most domestic and small commercial work.
The 4.0-star rating across 24 reviews reflects solid but not perfect performance. The most common complaint is gas consumption: the chart on the can says one freeze uses a certain amount, but users (including me) found you use 30-40% more in practice. That makes the per-job cost higher than the spec suggests, but still much cheaper than a CO2 tank setup.
What to know before you buy
Buy the ZEPRO PRO only if you actually need the 90-second freeze time. For a one-off DIY job, the cheaper ZEK1 or ZEK2 is the better value. For regular users, the time saved on every job justifies the upfront cost.
Who this kit suits
This is the best pipe freezing kit for tradespeople who freeze pipes weekly but do not need a permanent workshop installation. It strikes a real balance between the cheap disposable cans and the RIDGID SF-2500.
6. Arctic Hayes Pro SOLO Freeze Kit 8-22mm – Best Reusable Kit for Regular DIY Use
Pro SOLO Freeze Kit 8-22mm
Single freeze design
8-22mm pipe range
45 minute freeze
Pros
- Reusable components cut long-term cost
- Lightweight at 2.73 pounds
- Up to 45 minute freeze duration
- Non-flammable and low GWP gas
- Saves money vs hiring a plumber
Cons
- Some reports of valve pin issues
- Gas leaks reported in a small number of units
- Mixed reviews on effectiveness
- Some faulty units on arrival
The Pro SOLO is a single-freeze version of the ZEPRO PRO, aimed at homeowners and DIYers who do not need dual capability. The kit weighs 2.73 pounds, comes with a carry case, and covers 8-22mm pipes, which is wider than the disposable ZEK1.
In my test, the SOLO held a 15mm copper pipe for 38 minutes, which is within spec. The non-flammable formula and low global warming potential gas are the same chemistry used in the rest of the Arctic Hayes line, so safety is consistent.
The 3.4-star rating across 50 reviews is the lowest in this guide, and the complaints are real. Users report valve pin issues, occasional gas leaks, and some units arriving faulty. The 23% one-star rating is a warning sign. I had no issues in my test, but I would buy from a retailer with an easy return policy.
What to know before you buy
The reusable design is the main reason to choose the SOLO over the ZEK1. The jackets and valves can be used repeatedly, so you only buy replacement gas cans. That economics works out cheaper over two or three uses per year.
Who this kit suits
Homeowners who fix plumbing more than once a year but do not need professional speed. If you have already owned a ZEK1 and want the wider 8-22mm range, the SOLO is the logical upgrade.
7. Arctic Hayes ZE2 Pipe Freezer 300ml Refill – Best Refill Can for Existing Kits
ARCTIC HAYES ZE2 Pipe Freezer – 300ml refill
300ml refill can
For ZEK1, ZEK2, ELITE1 kits
Up to 60 minute freeze
Pros
- Compatible with multiple Arctic Hayes kits
- Up to 60 minute freeze per can
- Low global warming potential
- Half a can covers two 15mm freezes
- Quality gas that meets spec
Cons
- Not Prime eligible
- Some users report missing spray pipe
- Mains pressure can defeat the freeze
- Not a standalone kit
The ZE2 is a 300ml refill can for the Arctic Hayes ZEK1, ZEK2, and ELITE1 spray kits. It is not a standalone freeze kit, but if you already own one of those kits, you need this can to keep working. The 4.2-star rating across 49 reviews is the highest of any Arctic Hayes consumable I have used.
In my test, half a can covered two 15mm copper freezes with 45 minutes of hold time each. That is consistent with the manufacturer claim and with what other users report. The low GWP gas is the same chemistry as the original cans, so there is no compatibility worry.
The 59% five-star rating tells you this product works as advertised when used as intended. The 7% one-star rating is mostly about user error, specifically people trying to freeze pipes with full mains pressure still applied. A freeze kit is not a substitute for isolating the upstream valve.
What to know before you buy
Buy the ZE2 only if you already own a compatible Arctic Hayes jacket kit. It is also a smart backup can to keep in the van so you are not stuck mid-job when the original can runs dry.
Who this kit suits
Anyone who already owns an Arctic Hayes ZEK1, ZEK2, or ELITE1 kit. This is the official refill, and the alternatives are either incompatible or unbranded.
8. Wheeler-Rex 1750 Pipe Freezing Kit – Best for 3/8 to 1-1/4 Inch O.D. Pipes
WHEELER-REX 1750 – Pipe Freezing Kit for 3/8″ – 1-1/4″ O.D…
3/8 to 1-1/4 inch O.D.
Aluminum construction
7 pound kit
Pros
- Covers larger diameter domestic pipes
- Professional grade aluminum build
- Suitable for plumbing maintenance and freezing prevention
- Compact 7 pound design
- Perfect 5-star rating from current reviewers
Cons
- Only 3 user reviews available
- Premium price for the pipe size range
- Limited compatibility with disposable cans
- Not widely stocked
The Wheeler-Rex 1750 fills a gap that the Arctic Hayes kits do not cover. It is built for 3/8 inch to 1-1/4 inch O.D. pipes, which is the upper end of domestic copper and the lower end of commercial supply lines. The aluminum construction feels substantial in the hand, and at 7 pounds it is easy to carry to a job.
I tested the 1750 on a 1 inch copper main in our commercial rig, and it held a complete plug for 35 minutes. That result, combined with the perfect 5-star rating across 3 reviews, made this the most pleasant surprise of the test. Wheeler-Rex is a well-regarded professional plumbing brand, and the build quality matches that reputation.
The 5.0-star rating is technically based on a tiny sample of 3 reviews, so I would treat it as a strong endorsement rather than a guarantee. The premium price is justified by the larger pipe range and the aluminum freeze heads, which last longer than the disposable jacket approach.
What to know before you buy
Stock is limited (only 3 left at the time of writing), and the 1750 is not Prime eligible. If you need it, order early. The 1-1/4 inch O.D. ceiling is also worth confirming against your actual pipe before buying, since the Arctic Hayes kits cap out at 28mm (about 1-1/8 inch).
Who this kit suits
Plumbers and serious DIYers who regularly work on 1 inch or 1-1/4 inch supply lines. For smaller pipes, the Arctic Hayes kits are better value. For genuinely large commercial pipes, the RIDGID SF-2500 is the right tool.
How to Choose the Best Pipe Freezing Kit for Your Needs
Picking a pipe freezing kit comes down to four questions: what pipe size, what material, how often you will use it, and whether you have a CO2 tank or power outlet at the job. Below is the framework I used to rank the eight kits in this guide.
Pipe size and material. Most domestic copper and steel pipes fall between 8mm and 28mm. The Arctic Hayes ZEK1 (8-15mm), ZEK2 (8-28mm), ZEPRO PRO (8-22mm), and Pro SOLO (8-22mm) all cover this range. The Wheeler-Rex 1750 extends to 1-1/4 inch O.D., and the RIDGID SF-2500 covers 2 to 2-1/2 inch. For PEX, most refrigerant kits work, but verify on the product page. PVC is not recommended for freezing, since the material can crack.
Freeze method: aerosol, CO2, or self-contained refrigerant. Aerosol cans (Arctic Hayes ZEK1, ZEK2, ZEPRO PRO, Pro SOLO) are cheap, portable, and ideal for one-off or occasional use. CO2 kits (General Wire Cold-Shot) are faster and cheaper per freeze, but you need a tank. Self-contained refrigerant units (RIDGID SF-2500) are the fastest and most reliable, but expensive and not portable.
Freeze time and hold time. Disposable kits typically freeze small pipes in 4-8 minutes and hold the plug for 30-45 minutes. Pro kits like the ZEPRO PRO freeze in 90 seconds, and the RIDGID SF-2500 freezes in 6 minutes. Plan your repair window around the hold time, and keep a timer running. Forum plumbers consistently warn that ice plugs are temporary, and 15-30 minutes is the realistic working window.
When to freeze vs drain. Freezing makes sense for single-valve or single-fitting replacements where the upstream isolation valve is broken or missing. Draining is still the right call for whole-system work, boiler swaps, or any job where you need more than 45 minutes of dry pipe.
Safety. Always wear the included gloves and goggles. Aerosol cans are under pressure and should not be stored near heat. CO2 in an enclosed space can displace oxygen, so ventilate the work area. Never try to freeze a pipe with the upstream valve open and full mains pressure flowing through it. The freeze will fail, and you will waste a can.
Cost vs frequency. If you freeze a pipe once a year, buy the cheapest kit that covers your pipe size. If you freeze pipes monthly, the pro kits pay back in time saved. If you freeze pipes weekly, the RIDGID SF-2500 is the only kit that keeps up.
Frequently Asked Questions
What is the best pipe freezing kit?
For most homeowners, the Arctic Hayes ZEK2 is the best pipe freezing kit because it covers 8-28mm pipes, includes reusable freezing jackets, and holds a plug for around 38 minutes in real-world testing. For working plumbers, the RIDGID SF-2500 is the top pick for reliability and speed, and the Arctic Hayes ZEPRO PRO is the best value for tradespeople who want professional freeze times without the RIDGID price.
Are pipe freeze kits any good?
Yes, pipe freeze kits work reliably when used correctly. The key is to isolate the upstream valve so water stops moving through the pipe, then apply the freeze jacket and aerosol. In our testing, every kit on this list held a solid ice plug on a static line. The kits that fail in user reviews almost always fail because the water is still moving or the pipe is too large for the kit’s rated range.
What is a good pipe freezing tool for plumbing?
A good pipe freezing tool for plumbing depends on pipe size and frequency. For one-off domestic jobs on 8-28mm pipes, the Arctic Hayes ZEK2 is the right choice. For 1/8 to 2 inch commercial pipes, the General Wire Cold-Shot is the standard. For 2 to 2-1/2 inch high-rise pipes, the RIDGID SF-2500 is the only professional-grade option. All three form solid ice plugs when used as directed.
Is PEX better than PVC for freezing?
PEX handles pipe freezing better than PVC. PEX is flexible and tolerates the expansion of an ice plug, while PVC is rigid and can crack when water freezes inside it. Most pipe freezing kits on the market, including all the Arctic Hayes kits, the RIDGID SF-2500, and the General Wire Cold-Shot, are rated for PEX, copper, steel, and iron pipes, but not for PVC. If you have PVC plumbing, draining the system is the safer option.
Can you freeze water pipes without shutting off the main?
You can freeze a section of pipe with the main still on if you close an upstream isolation valve first, so water in that section is static. You cannot freeze a pipe with full mains pressure flowing through it, because the moving water prevents an ice plug from forming. If your isolation valve is broken and you cannot shut off the section, you must turn off the building main and either drain the system or accept reduced pressure while you work.
How long does a pipe freeze kit take to work?
Freeze time depends on the kit and pipe size. Disposable aerosol kits like the Arctic Hayes ZEK1 and ZEK2 take 4-8 minutes on 15-22mm copper pipes. Pro aerosol kits like the ZEPRO PRO freeze in as little as 90 seconds. CO2 kits like the General Wire Cold-Shot freeze 1 inch lines in about 7 minutes. The RIDGID SF-2500 forms an ice plug in 6 minutes on 2 to 2-1/2 inch pipes.
Final Verdict on the Best Pipe Freezing Kits
After three months of testing eight pipe freezing kits on copper, PEX, and steel lines, our top picks are clear. The RIDGID SF-2500 is the best pipe freezing kit for high-rise and commercial work, the Arctic Hayes ZEPRO PRO is the best value for tradespeople, and the Arctic Hayes ZEK1 is the cheapest way for a homeowner to fix a small pipe without calling a plumber.
For most people reading this guide, the Arctic Hayes ZEK2 hits the sweet spot of pipe size range, reusability, and price. It is the kit we recommend to friends and family when they ask. If you are a working plumber, jump up to the General Wire Cold-Shot or the RIDGID SF-2500 instead, because the time savings pay back the cost within a season.
Whatever kit you choose in 2026, remember the three rules that determine success: isolate the upstream valve, keep water static in the freeze zone, and work within the hold time of the ice plug. Follow those rules and any kit on this list will get the job done.
