Rated 4.6 out of 5 by 17 reviewers.
Rated 5.0 out of 5.0 by Excellent tool, easy to use and great build quality The expansion tool is made of high quality materials and should last, like most Milwaukee tools. Extremely simple to use and makes leak free connections every time without any guesswork. The tool is pretty pricey, but in my case, I'm re-plumbing my entire home, and it makes connections so simple, it was more than worth it. February 26, 2013
Rated 5.0 out of 5.0 by Do PEX the professional way Well, first I should say that I'm no plumber, not even close. I'm an IT guy. But I own a old house with well water, and after 33 years, the acidic water had eaten through the pipes to the point where a pin hole leak and burst could happen any day. These often happened at the most inopportune time, though obbiously, no time was ever good. I would turn off the water at the home's main valve to save us from a flood. And aas to have water through at least some of the house, I eventually installed valves on the hot and cold run to the second floor, which bought a bit more time. But having to cut open the ceiling in my kitchen to make six repairs over the past year meant I needed to buy time and find a long term solution. Replacing the copper with copper could theoretically buy me another 30 years. But that would require a plumber, and these days, both the material and labor would be prohibitively expensive. PVC/CPVC seemed like a good option, but the flexibility of PEX presented a clear advantage in more than matching the bends the original (a true artist) plumber employed. At first, I went through the normal crimp vs clamp debate that most who shop at the big box stores encounter. Which is better? Well, we all know there's some in each camp. Further research brought me to I look at the more costly means, including this Uponor (Wirsbro) system, this Milwaukee tool supports. Yes, a $400 tool is quite an investment for most people. Especially, if you're going to use it once, and then move on. However, I believe in weighin the value of decisions, and the $400 vs the hiring of a plumber seemed like an attractive proposition. The other obvious and big downside of this system is that though you can buy the tool here at The Home Depot, you cannot buy the PEX-a tubing and fittings there. For that, you'll have to find a local or online seller, I opted for the latter. Before I go any further, I found that though there was a local rep who referred me to several supply houses, neither had the stock or knowledge to adequately support me. I quickly realized an online seller, who always got what I needed to me within one day was the way to go. One huge advantage of this system, however, is that the fittings used in the crimp and clamp methods seriously restrict waterflow, which with a well and not very strong flow to start with, I didn't want to deal with. The Uponor system doesn't restrict flow; more on that later. Now on to the meat of the matter... This system is simply a pleasure to use!!! The material is easy to work with, the Uponor (made in the USA and Canada) fittings are a beauty to hold and behold, and makes the stuff you find at the big box stores look and feel like the made in China junk it is. In other words, the quality and precision borders on the awe inspiring. Also, the Uponor valves deserve mention for their simplicity, quality, and ingenious way of working. As I previously stated, I'm no plumber, and I'm not even remotely close to being a plumber. But this system will allow anyone of average intelligence and ability to do a beautiful job. You simply cut the tubing where you need, slip on a compression fitting, have ready what you'll fit it to, use the tool to expand the tubing/compression fitting approximately 3 times more than it takes to get it down to the base of the tool, and make the connection within 3 or 4 seconds. Honestly, there is nothing that allows you to work anywhere near this fast or sure. I did my entire first floor in a day, and most every connection went quickly, smoothly, and easily. Now, the moment of truth. Unlike the time involved in sweating copper or waiting for PVC adhesive to cure, the connection is really to be pressurized more or less immediately. I would not have been surprised to find a few leaks, but I crossed my fingers, as I opened each valve, and all I heard was the very quiet (boy, is PEX ever quiet!) sound of the pipe being pressurized. No leaks at all, not a one! Within a few minutes, I had the first floor online, and remarked at both how much more pressure and volume I now enjoyed and how silent the system was. Again, they do tell you unlike going with the popular crimps or clamps, this Uponor offers no flow restriction whatsoever. I'm here to tell you to take that to the bank. As I said, in fact, I have realized a nice improvement. After now cutting the ceiling out around all of the pipes, I'm about to embark on the second floor conversion, which is a lot less involved than the first floor. Yes, this $400 Milwaukee/Uponor system represents a real investment. Yes, it seems like it may not make a sound connection when you see the photos or videos. And, yes, there are also other professional (Viega and Rahau) systems on the market. But for the person or plumber who is reading this, I can assure you, this is a fantastic and professional way to go. It's incredibly fast, easy, and sound. September 3, 2014
Rated 5.0 out of 5.0 by Expansion Tool Kit Using this tool to finish building my vacation home. A little pricey, but does a great job! April 21, 2015
Rated 5.0 out of 5.0 by Milwaukee is the Chuck Norris of tools I own a lot of Milwaukee power tools and love them always durable and don't have issues with them. I purchased the Milwaukee M12 Pex expander and love it. I used a manual expander tool before and it takes time and results were not as exact as this tool. The Milwaukee rep at the store is awesome, super knowledgable he knows Milwaukee. The tool works great pull the trigger it expands and rotates automatically can't complain about that. It feels solid and works solid I don't feel like this tool will wear out, overall a great buy. May 23, 2014
Rated 5.0 out of 5.0 by Great tool, works as expected I am not a plumber, but I do my own work at home under the supervision of a friend who is a plumber. He has this exact tool and recommended it. I had a couple of plumbing projects coming up and I wanted to use the same pex pipe he uses (Wirsbo) so I bought the tool. Was it worth the price for the kit? I dunno. I had the money and wanted a quality job (and to do it myself) so I bought it. Probably the way I can justify the expense is to use it to help friends who have simple plumbing projects of their own. It's extremely easy to use - just be sure to follow the instructions. I have never had to re-do a joint. If you have a DIY personality and want to delve into pex plumbing I think this tool is perfect for you. I actually look forward to new projects just so I can use it... May 1, 2013
Rated 5.0 out of 5.0 by Excellent Tool for ProPex Used this tool for expanding Uponor tubing and worked flawless, would recommend this to anybody February 17, 2015
Rated 5.0 out of 5.0 by Tool works great; Home Depot is great to deal with! The first tool I ordered was received damaged as the product wasn't properly packaged. I contacted Home Depot and they gladly shipped another tool and sent instructions to their shipping department that the tool needed to be packaged properly. I received the new tool in a few days and true to their promise, it was properly packaged. While using the Propex expander, it malfunctioned when I changed the heads. I contacted Milwaukee, and they indicated that some tools had an issue with an internal pin that would cause an intermittent failure such as the one I experienced. They encouraged me to return it for a refund, or back to them for repair. I opted to return it to the Home Depot and order a new one. The bottom line: I buy a lot of tools and products from Home Depot because they stand behind the products they sell and are great to deal with. September 2, 2012
Rated 5.0 out of 5.0 by Pex expander great tool Been doing plumbing for a while now, it's a must have tool while running pex tubing. Speeds up production like you wouldn't believe August 19, 2014
