COMPACT ZUPPER PZ-2430 18V Copper Press Tool Kit PZ-2430 1/2'', 3/4'', 1'' Jaws

Great tool! Crown Tool answered all my questions and concerns. They’re very easy to deal with.

The Zupper PZ-2430 press / propress tool works great. I've used the Milwaukee compact M12 tool + jaws as well, and I can say they are basically the same user experience. Both jaws fit onto the joints and crimp the fittings well and both resulted in zero leaks in a dozen or crimps on two separate jobs I've done. What I really liked about Zupper is how well-balanced it is for one-handed use, allowing me to press the joint together with one hand and run the press tool cycle with the other. I had some serious misgivings about buying this brand given how little-known it is at this time, however I was super pleased I did. This tool does the same job as the Milwaukee (or Nibco, Ridgid, etc.) at a fraction of the cost. Absolutely perfect for homeowners. Especially if you run Makita 18V tools as these use the same batteries.

Attached are some pictures of the tool case and a bypass loop I added when putting in a new water softener at my house.

Crown Tools are also fantastic. I emailed/called them a few times to talk about this tool before and after buying and their support is super responsive and helpful. I would definitely be happy to buy from these folks again. They are an authorized reseller of Zupper Tools, one of only a few currently in the US. So you know you'll get proper support from the manufacturer if something does need repair.
