IWISS/iCrimp PEX Pipe Copper Ring Crimping Tool Kit for 3/8 in, 1/2 in, 3/4 in, 1 in Crimp Rings, Meets F1807 Standard (13" Combo PEX Crimper)

I ran some underground water lines to my work shop and this made the project so easy. Just follow the instructions, use the ring guide to make sure the clamp is clamped to the right size.

I am very handy and have done 2 bath renovations that included copper plumbing, electrical, drywall, tile and everything else that goes into a bathroom rebuild from the studs out. I am in the process of doing a reno on a new house that has PEX and I wanted to learn how to do it. There are plenty of tools available for this at the local home stores, but after doing my research on the Internet, I settled on this IWISS tool as the best PEX crimper for my DIY needs. I am not disappointed. The tool is very sturdy and solidly built. I only needed 1/2" crimps but it also provides for 3/4" crimps. I did not foresee nor need anything bigger or smaller for my DIY needs.Being my first time using PEX plumbing, I did a test crimp. That first one was simple enough to do and I felt the satisfying click of the tool as it completed the connection. It also passed the inspection using the provided go/no-go tool. So I laid out the new shower valve and all the connections for hot and cold lines and the shower head and handheld. I cut all PEX lines to fit and dry fitted the fittings as well. I also thought about how to put the connections back together and the sequence of the crimps, because even though PEX is a lot more flexible than copper, it's still pretty stiff when you're working in tight quarters. In all, there were 22 PEX connections to be made, so I shut off the water to the house and started crimping the connections. I was done in less than 45 minutes with all 22 crimps. This included 15 minutes to redo one connection because I did not seat the PEX all the way into the fitting for my comfort and redo another connection because I could not get the other side of the elbow to go into a tight squeeze. Because I needed to reuse the PEX tube (it was already cut to size), I used a dremel to cut to copper rings enough that I could use a flat head screwdriver to split it. I stopped the dremel short of seeing the blue of the PEX line and copper is a soft metal to split.This job would have easily cost $150 or much more if a plumber or handyman came out to do it. With this tool, some elbows and copper rings, I did this for much less than half and I learned how to do PEX in the process. I think I like PEX now that the initial learning curve is done and I can appreciate why the trades like it so much over copper. It's much easier and so much faster to work with. If you don't do this for a living, this tool is great for the DIY'er. And it provides great bang for your buck.

100% recommended

Simple and truthful review: This is a sturdy and easy-to-use tool that crimps copper Pex rings tight, on the first try. It is a little stiff when it arrives, and I suggest lubricating the moving hinge connector when you get it. But it is simple, and although many people swear by Shark Bite connectors, I really do not trust them as I have had a few of them fail in critical spots. Although the tool is a little pricey, it makes up for it through the savings on the pipe connectors. For example, a Shark Bite reducer T is 15 bucks on average. A brass Pex T, about 3 dollars. Heck, buy some compression rings and have at it. These work well, plain and simple. You can see a simple connection in the picture above. 15 minutes and done. These same joints failed with push-to-fit connectors.

Super useful and well made!

Last year we remodeled our upstairs bathroom. I paid a licensed plumber to install a new shower faucet. It leaked and he had to come back 3 times. It cost me $250 and missed work. He never said, "sorry". This year we decided to do our downstairs bathroom. Rather than go through a similar hassle, I decided to do my own plumbing. After watching a few YT videos and researching tools/fittings, I decided to buy this tool. The job was way easy and, NO LEAKS when I finished.The tool is quite sturdy and seems well-built. It is a bit tough being able to open the jaws wide enough to get it around your pipe/fittings given I was working under my house but, any similar tool would have the same issue. It crimped all PEX fittings per instructions and it went well and quickly. Now I can do my own plumbing when I need to and not worry about getting some hack plumber. I recommend this tool.

Works great. Mine came calibrated perfectly. No adjusts needed. Easy to use. I used this tool to make tight crimps of copper rings on PEX-B pipe and fittings. One crimp and no leaks. I highly recommend this tool.
