This is a great tool for the price. Is it contractor grade for everyday use use? No. But it’s great for the DIY homeowner. Comparing this to the Milwaukee is just ridiculous. Milwaukee’s pex tool is more than 5x the price of this Ryobi so anyone comparing the 2 are out of touch. My only gripe is the jaws are very large so it’s easy to crimp a ring crooked if you’re not paying attention or holding it properly till the jaws engage the ring. Once you get used to it it will save you tons of effort and time with your project. And it’s $80 cheaper on Amazon than it is from Home Depot so to get this tool for sub $200 is a win.

For the price works great easy to use very adjustable for different sizes

This tool worked as described. However the jaws tend to stick after crimping and pull out of the tool. Its also a bit heavy and does not work in confined areas. However if you have a lot of crimps to make, it is worth the money. But I would also have a pair of hand crimpers as well

Purchased March 2024. I've crimped less than 50 rings & it's fried, toast broken! Will not work at all. Talked to Ryobi about warranty repair or replacement and they said Amazon & none of the sellers are not authorized resellers and EVERYTHING Ryobi on here are REFURBISHED & have NO WARRANTY! again DO NOT BUY ANYTHING RYOBI on Amazon. Worst part about this is nothing no where here said this was a refurbished unit so I assumed it was new. Total SCAM! I could have bought a new one at Home Depot for the same price but all the stores in my area were sold out.

Ryobi has come up with a great little tool. It’s easy to use and it fits in narrow spaces which makes it a time saver.. No more trying to use upper body strength in odd places to crimp the pex rings.. If you do a lot of pex work, this tool is worth the money an saves time.. The only negative is changing out the ring dies, it has a push in button release an if you hit them by mistake while releasing the jaws, the ring dies come off

I am running PEX through the floor joist on the second floor as part of a remodel. I am install radiators as well. Some of the crimps are in tight places. This crimper lets me make the crimps with ease. It works so well, I am using it for all my crimps. I am even doing more crimps in the floor, rather then doing as much prefabrication as I was doing. It is making the job go much faster, and without as much wast. I may never use my hand crimper again.

I had to do a total replumb with PEX after a very rare Texas freeze shattered the CPVC under my house. I first used a manual ring clamp tool, but I lacked the upper body strength to use it in some areas where I had to reach out and hold it in awkward positions. I took the plunge and invested in this Ryobi battery operated tool. I have several of the Ryobi 18V tools, and, as a whole, I lo e the collection. They're very reliable, and after making the initial investment for the batteries and chargers, it's really affordable to keep adding to my personal tool collection. I still ha e all the tools from the original set of blue and yellow tools I bought in 2006, after realizing that as a newly divorced woman, I had to learn to all the things I'd thought of as man-work previously. I was hooked and became an avid DIYer. When I married my current husband, he also had many of the tools in the set and we've just kept adding. So I was so happy to see just the tool I needed was available for the system. After reading other reviews I was prepared for some of the rings to close in an oblong shape that wouldn't fit in the go indicator from all angles. I found that to be the case with my new tool, so, from the beginning, I crimped each ring twice, turning it 90 degrees for the second crimp. This method worked well. Initially I just did some emergency repairs, replacing the main supply line and lines to get us a working toilet, shower and kitchen sink. I was able to do it with the hand tool, but it was extremely difficult and I realized there were some areas under the house that the toil just wouldn't fit in the open position. But, eventually, I was able to restore water supply, both hot and cold, to those absolutely necessary fixtures. After about a month of dealing with an insurance adjuster I found out that our policy covers the damage done by the ruptured pipes, which was pretty extensive, but not the actual pipes themselves, so I'd have to do the rest of the replumb myself. I knew I wouldn't be able to replace every supply line under the house using the hand tool. I shouldn't even call it a "hand" tool, since most of the time I closed it by laying on my back with my legs in the air squeezing it between my knees. Picture an inverted thigh-master user under a Mobil home. That was me. In other areas, where the ground was lower under the house, I used whatever method I could to close it, including using both hands on one arm of the lever, while bracing the other against any firm body part that could reach the area of the connection, including my shoulder or even my cheek bone in some cases. I was so sore and covered in bruises. I used my new Ryobi tool to restore supply to several other fixtures and to replace some of the push-to-fit connections I'd used initially when I thought there was just a single break in a single line. Using my 90 degree double crimp technique, I had no problems at first. I broke the job down into several smaller jobs and added in or made improvements to as parts became available. (There was a serious shortage of plumbing parts and tools after the freeze since so many homes had lost the majority of their plumbing. As time went on, more and more, I started getting connections that would fit the go side of the go-no-go tool, but only with a little force and wiggling, and I'd get more and more that just wouldn't fit and had to be redone. Then, more and more that seemed to fit, admittedly a tight fit, would end up leaking when tested. Eventually, very few of the connections I'd make would work. Luckily, at that time, I was working inside at the distributor area, and had better access. I had to replace those with steel clamp rings after many many tries with this tool. I still had alot of work to do under the house. I ruled out the problem being with the rings themselves, or with the connectors or with some sort of defect in that particular roll of PEX. I could get good connections on the same materials with the hand tool I still had. It had to be this tool. All the hand tools have an adjustment knob. They say that as the tool is used, it has to be tightened. This tool has no adjustment knob. It seems o me like this tool would suffer the same loss of tolerance that the hand tools do over time, but there's no way to adjust for it. For the rest of the connections under the house, I've been using this tool for the initial crimps, then tightening the rings the rest of the way with the hand tool. After doing the majority of the work with the battery operated tool, I don't have to open the hand tool as wide so I don't need as much room, and I don't need to use nearly as much force to get a good crimp so it's working so far. I will still have some work to do after the non plumbing repairs are completed later this month, and I'm hopeful I can get through the job with this method. An additional problem I had was that the tool was damaged when I recieved it. One of the spring loaded posts that holds the different sized plates was bent. After a few hours of use, it bent. I was able to improvise with a small screw and nut in its place. That works fine. In fact I like it better because it holds the plate more securely. Under normal circumstances I would have returned the damaged tool immediately but the wait for a new one would before than a month and I couldn't wait. Even with all these problems, I'm still really glad I bought thos tool. I wouldn't have been able to do what I've done without it. I still can only give it 3 stars simply because it's supposed to do the job by itself, and it just doesn't do that. Normally I wouldn't recommend a product I'd only rate 3 stars, but in this case, I'd say you should give it a try under certain circumstances. If you ha e a large job or areas where you just can't close a hand crime tool, give it a try. Whenever possible, I'd buy it directly from that big orange home improvement store because they have a 90 day return policy instead of 30. If you're breaking up a large project over several weekends, you're likely not to encounter problems within the first 30 days so keep that in mind. To sum it up, love Ryobi 18V tools Love the ease of use. Do recommend you try this product. But also recommend you're not counting on it to work perfectly and you're prepared to improvise and have a back up plan before starting a job, especially one that you're depending on to be able to flush a toilet or take a shower! Update: I figured out a way to deal with the problem I had with the tool not closing the rings as tightly after some use. I put a layer of electrical tape on between the tool and the adapter things that actually squeeze the rings. Sorry, I'm having trouble coming up with the right words but I hope that helps anyone having the same problem I was. Now, the rings are completely squeezed shut and I don't need to go back over them with a hand tool.
