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! Review: Excellent tool - Smaller size so I can work in cramp spaces which is a major plus. I had to set the adjustment to 3 to pass the go/no go gauge. Increasing the adjustment required more effort to crimp. I think setting it down to 2 would have worked (less effort to crimp) but I did not want to take any chances on permanent water line repairs. Again probably setting it to 2 (which making crimping effort acceptable) would have worked for more experienced people--I wanted to make sure. Highly recommended for the price and love the smaller size. ## Features - Meet ASTM F1807 Standard, compatible with 1/2-inch and 3/4-inch copper ring in PEX pipe connection - Well-polished jaws ensure no damage to the copper rings to avoid leaking - Constructed of durable steel ensure an integrated mechanical property and calibration function supports a long service life - Lightweight and short handles improve the performance of operability in narrow space - The innovative new design saves deformed rings and Pre-crimping function brings quick&easy installations ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0727RY8FC | | Best Sellers Rank | #72,897 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #257 in Crimpers | | Brand | IWISS | | Brand Name | IWISS | | Color | Red | | Customer Reviews | 4.7 out of 5 stars 1,952 Reviews | | Grip Type | Ergonomic | | Handle Material | Alloy Steel | | Handle Type | Fixed | | Included Components | no | | Item Weight | 1.2 kg | | Manufacturer | IWISS TOOLS | | Manufacturer Part Number | IWS-1234PS | | Model Number | 1/2" & 3/4" Crimping Tool (Standard) | | Set Name | Combo Set | | Size | 1/2-inch, 3/4-inch | | Specific Uses For Product | Plumbing, HVAC installations and repairs | | Specification Met | ASTM F1807 | | UPC | 709619251529 | | Unit Count | 1 Count | ## Product Details - **Brand:** IWISS - **Color:** Red - **Grip Type:** Ergonomic - **Handle Material:** Alloy Steel - **Item Weight:** 1.2 Kilograms ## Images ![iCrimp PEX Crimp Tool for 1/2" 3/4" Copper Ring ASTM F1807 - Image 1](https://m.media-amazon.com/images/I/51Ffe-7RnkL.jpg) ![iCrimp PEX Crimp Tool for 1/2" 3/4" Copper Ring ASTM F1807 - Image 2](https://m.media-amazon.com/images/I/71Hu+gNkgIL.jpg) ![iCrimp PEX Crimp Tool for 1/2" 3/4" Copper Ring ASTM F1807 - Image 3](https://m.media-amazon.com/images/I/71uRY23JSZL.jpg) ![iCrimp PEX Crimp Tool for 1/2" 3/4" Copper Ring ASTM F1807 - Image 4](https://m.media-amazon.com/images/I/71bNFsmoqML.jpg) ![iCrimp PEX Crimp Tool for 1/2" 3/4" Copper Ring ASTM F1807 - Image 5](https://m.media-amazon.com/images/I/71a-jFul5qL.jpg) ## Available Options This product comes in different **Model** options. ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best Value I could find *by P***G on May 5, 2020* For a homeowner who doesn't do plumbing every day, these worked very well.
