iCrimp 1/2 and 3/4-inch Combo Pex Pipe Crimping Tool for Copper Ring with Gauge meets ASTM 1807 Standard-manufactured by IWISS

Great quality

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!

Like you can change the dies

Sent back, didn't need, great price

I was pleased with the quality of this tool. It's so easy to switch the jaws back and forth from 1/2" to 3/4". It has easy adjustments if you need to fine tune the squeeze. However, I had no need to do so as the factory setting passed the go - no go guage with one crimp.

My husband is a plumber in he likes to use this product

Goodness these are miles better than push fittings. This tool makes it so easy to use crimp fittings instead, and the crimp fittings are so much cheaper. Plumbing jobs and repairs become so much cheaper now. And I find it even easier easier to crimp a ring than push a pipe when you're standing underneath it and no step ladder or etc.Highly recommend crimp fittings if you've been using push fittings!

I'm new to the world of Pex and needed a crimping tool. This tool works great. I'm very satisfied with it.
