    • Saves so much time - definitely worth it.
It was much cheaper than the Milwaukee brand and works so well. The only issue is it doesn't come with a battery, so you need to have Dewalt batteries. I already have 3 so didn't need one and saved money not having to buy the battery. There's no way I could do my pex plumbing without this thing. I started out with a manual expander and while it's a good workout, not feasible for doing more than 5 connectors a day - you too muscle fatigues with the manual expanders. Each extender takes like 15 seconds and you just pull the trigger. Can't believe I waited so long to buy it. ... show more

    • What a great tool, PEX-a all the way.
Review Image by Clin Clin
The media could not be loaded. I have a Dewalt battery, so getting this over the Milwaukee version was an easy choice. I can’t talk enough about how easy this has made plumbing. It gets almost anywhere a crimper tool can get and some new places; you don’t have to pull apart handles to work the tool. I replumbed half of a house using it and the only thing that leaked was an NPT connection that tied into old work. I’ll probably use a Sharkbite next time for the old work. The kit includes three heads, 1/2, 3/4, 1 inch. The video I included with this review shows the 3/4 head. They screw on easy enough. You should apply the included grease when changing fittings. The trigger is huge and easy to use. The case is for-purpose and nice to have. This isn’t like a hammer or screwdriver; unless you plumb often you’ll want something for longer storage between use. The only two things that I could complain about with this type of PEX (a or expansion) is the availability of fittings in local stores (only Lowes seems to carry them), and trying to find a place to put the tool after you’ve expanded. The belt clip helps with that, but it’s heavy. It is best to plan a location to set the tool. ... show more

    • Great tool
Love this tool for installing pex A. The only thing is it does struggle just a bit with 1” fittings. I have to expand longer in order to stretch the coupling long enough for fit up. Other than that it works great

    • This tool works great
I installed pex A in my entire house with this tool and it works great. I am not a plumber. Every single joint was made with no leaks on the first try. This tool makes it too easy to complete plumbing yourself.

    • Meets my needs as a DIYer
This is obviously much more efficient than the manual tool for PEX expansion. I’ve used it to repair plumbing for an auxiliary building and my landscape irrigation line. It operates as expected and I haven’t had any issues so far. It comes with the 3 heads, the lube and the case, as described. It was also less expensive than competitors’. I’m happy with it! ... show more

    • Great value for Pex-A Expansion Tool

As a general contractor, I use this PEX expansion tool all the time for capping off waterlines, as well as installing new plumbing fixtures for kitchen and bathroom remodels. It's easy to use and provides secure PEX connections. So much quicker and consistently better leakproof connections than the old copper sweat process. And shares the same Dewalt batteries as my other cordless power tools. ... show more

    • Do yourself a favor
I was new to PEX and figured I only needed a manual expander to do some 16 or so 1 inch (yes... One Inch) connections. I was soooo wrong. The magnificent pain of using a $120 tool was nearly debilitating! I had to replan and redo a few connections a month later and I finally broke down and bought this DeWalt Power Expander, it's so easy to use. I just hold the trigger in until expansion is done then shove in a fitting and ALL DONE! Though the description and pics didn't show it the tool did come with all 3 heads that handle the range of 3/8 to 1 inch. ... show more
