Milwaukee M12 Cordless ProPEX Expansion Tool
We like how Milwaukee seems intent on making a 12-volt tool for every single task that anyone has ever performed on a jobsite (we can't wait for the 12-volt Bobcat/Excavator combo kit!). Their latest, the ProPEX Expansion Tool is the most specialized yet.
What the tool does is expand the end of a piece of pex in order to utilize a particular fitting which is produced by a company called Uponor. A quick internet search turned up a manual expansion tool, a corded expansion tool, an air expansion tool, and a large clunky looking 18-volt expansion tool, all produced by Uponor. It's safe to say that none of these tools are as compact and nice looking as the Milwaukee.
For a little background, we found this at PexSupply.com:
The Uponor Wirsbo Expander system is perhaps the most widely used PEX system by professionals in the US. This system makes use of the ProPEX Expander Tool ProPEX Fittings, ProPEX Rings, and PEX-a tubing. If PEX-a tubing (AquaPEX) is not used the connections will fail. This system makes strong reliable connections that have never failed in the field. The only downsides to this system are the high up-front cost of the tool, the high price of fittings, and the fact that Wirsbo only wants professionals using the tools. Wirsbo has addressed the price of fittings by coming out with engineered plastic fittings that are more cost effective. Using the tool can be a little tricky at first, and Wirsbo prefers that only professional installers use their products.
There is no pricing information or release date available yet.
If you're curious what the process is like, here's a video of someone using a manual expansion tool. It's easy to assume that Milwaukee's tool will speed this process up quite a bit.
