I'm a plumbing contractor and appreciate great tools that help get the job done. I was a little skeptical due to the small size and light weight of the M12. But as soon as I started using it, I was impressed by it's speed and power. Next was to determine how long the battery was going to last. Batteries last reasonably long enough on 1/2" and 3/4" and OK on 1" which is way better than I anticipated due to the small size of the battery. This tool is typical of Milwaukee's high standard of engineering and quality. I did notice that there are larger batteries available for this tool which is nice to know in case I feel the need for longer lasting power on a really large job. The auto rotating heads are so convenient. In short, I love this tool and can't say enough good about it! But most importantly, it gets the job done quickly and easily AND there have been no leaks.

Comments about M12 ProPEX Expansion Tool Kit:
This is being used to repair Upon or PEX pipe my FORMER plumbers installed in my gypcrete floor. The plumber stapled down several "floaters" and didn't hold the staple gun down and flat to the PEX pipe puncturing it in several places throughout the newly poured floor. So it worked like a champ ! Totally satisfied with it !
Bottom Line Yes, I would recommend this to a friend

Made a hard job easy
All connection held great. No issues with operation of the expander. Looking forward to my next job I get to use it again.

Perfect for amateurs and professionals
from Woodbury, MN
I am a DIY homeowner and this tool was perfect for my needs for making changes/addition to my current Unior Pex plumbing system
Worth the $$$
from Acton, CA
This tool is a bit pricey, but the ease of use and speed that I could attach fittings was well worth it. I repiped my home, and it went very smooth and quick. I have even started helping friends and family out with their repipe projects as well, just to get a bit more use out of the tool. Compared to what plumbers were quoting me, I still saved several hundred dollars.
Worked great for adding a water softener and RO system to my existing water system. The only issue I ran into was when I was running low on lubrication. The expander would get stuck open, making it very hard to get the expansion ring off.
Good hand free tool
from PRESCOTT AZ
THE M12 IS A GREAT AND FAST INSTALLATION TOOL TO THE FITTINGS. CONVIENT COMPACT VERY WELL MADE.
M12 Pro Pex Expnsion Tool
By Bro. Brad the part time plumber
This tool is exceptional in it performance. As I need both the 1/2 and 3/4 inch option, I opt to purchase the entire set. Worked as advertised. Value wise it was a little more then the two handed pump type expander but was more user friendly. I weigh out the convince verses the cost with the Milwaukee coming out on top.

I love the size, weight and ease of use.
By Heaven's Gate construction
from Lancaster, Calif.
This tool automatically turns 1/4 turn with each pump up, preventing tube splits. This tool and Pex's pro-pex is THE best tool and product available. Crimping doesn't come close to this system.

The gold standard of pex systems
from Kettering, Ohio
Homeowner doing own re-pipe and wanted the best connection system for performance and ease of installation. Pricey, but considering the ease and quality of completed fittings, well worth the cost.
