Review: Best Value I could find - For a homeowner who doesn't do plumbing every day, these worked very well. I used to run Pex in my basement for a bathroom install with this tool. I ran both 1/2 and 3/4 with it and it performed well for both. I have more to do, so I will update if any problems come up, but so far this is a bargain tool. Ahead of time, I test crimped a few to make sure it didn't need to be adjusted. I went ahead and put it on the tightest mode, and the gauge said they were good crimps. If you have any experience with a go/nogo gauge, then there was no confusion. I understand most people wanting more clear instructions, but I thought they were straightforward. the line on the gauge should line up with the centerline of the hose. any less you need more crimp, if it passes the line, and you need less crimp. Adjustments were easy with a wrench. Effort to use tool was not unreasonable. Sure, longer arms would make it easier, but I like the compact nature of this tool. Some general tips for running pex plumbing I learned along the way: -- I did not buy a ring remover, and I had to cut off a few rings. I used a large pair of wire cutters with some elbow grease, and it worked. I still wouldn't spend the money on a tool for removal, personally. -- PLAN you runs before you start crimping. One of the aforementioned cuts happened because I crimped a piece on, then realized I could not fit the tool where I needed it to crimp the next leg- This is ESPECIALLY important on 3/4" pex due to the location on the crimper. -- after crimping, you do have the ability to rotate the fitting, although, it doesn't seem like a great idea to do a lot of, it is nice to know. -- buy a few more fittings than you need, don't open them until you use them, return the excess. This would have saved me a mid-project trip to home depot. As cheap and simple as this was, I think I will run air lines in my shop with pex now that I have this. 3 days in and no water leaks!

## Questions & Answers

**Q: Will the PEX crimper come with gauge**
A: Yes

**Q: Do I need to calibrate the crimper before every time crimp?**
A: No, the crimper is factory-adjusted, you can directly use it upon arrival. If the crimping result fail to pass the Go/No-go gauge, you will need reduce or add the numeric on the adjustments.

**Q: How should I calibrate the crimper?**
A: Add one numeric only in each calibration, i.e. change the default setting with numeric "1" and "2" to numeric "2" and "2". Tighten the locking nut and crimp again, if crimping result fail to pass the Go/No-go gauge again, calibrate it again.

Great value. Perfect for the home gamer looking to get some plumbing projects done.

### ⭐⭐⭐⭐ Works good, bit of a learning curve.
*by J***W on April 1, 2019*

Tool is very effective at crimping PEX rings. Out of about 250 connections I made this weekend, only about 4-5 would be considered "no-go" and needed re-clamped. None needed removed and replaced. This tool does need a substantial amount of grip strength to close, which can be an issue in tight places. It also opens just a little weird, where after releasing the handles, you need to pull back on one handle to get the jaws to fully open. I found it worked much easier to slightly pinch a ring using a pair of channel lock pliers, just enough to let friction keep it from sliding around, as the jaws on the crimp tool can bump the ring, moving it out of position easily. 4 stars out of five because, while it does its job well, its a little unwieldy. If I were a full time plumber, I'd probably look elsewhere, but as a DIY'er that might work on PEX a handful of times, its perfectly sufficient, and not overly expensive.
