Hydraulic Copper Tube Crimping Tool,Copper Pipe Fittings Crimping and Plumbing Tool with Crimping Dies Jaw 1/2", 3/4", 1"

I used this to repair two lines running to my hot water heater. The house builder decided to solder the flex connections directly to the pipes so this was my solution to crimp some actual hose bibs onto the existing piping. Fits into tight spaces, and makes a very secure crimp on the connector. I will definately be keeping this around for future house plumbing repairs as I have soldered fittings and valves all over the place that I am going to have to replace in the near future. If you're on the fence about buying such a cheap tool (check out Home Depot, the want at least $3,500 for similar electric tools) don't be. It does requre some strength to pump the hydraulic piston enough to get secure crimp, but it's very doable and I image it's a lot easier than using a leaver action crimp. Not to mention this thing is much more compact than other manual crimpers, I had no issues squeezing it into a tiny water heater closet to get the pipes crimped.

Good quality easy to use and I love it. I use it professionally at work and I have used it around 500 times already and as good as the day I bought it.

Great tool but gotta be careful it will over crimp

As a Commercial GC/DIY Homeowner, I do enough plumbing to know what I'm doing, but no where close to being an expert. The one area that I historically suck is sweating copper. This tool made it very easy Notes for users: - I recomend only using Type L Copper. Not sure Type M will hold up to the pressure of the tool. - Make sure to fully prep your connections just as if you were soldering. Very critical - Fit everything up before you start crimping, and put alignment marks on both the pipe and the connector - Plan your sequencing, and drill holes in studs and top track/plating such that you will be able to crimp inside the wall cavity. It's easy to get yoursef into a position where you cannot crimp a joint due to obstructions. - Be aware of the twist that occurs after you crimp multiple joints in a run. Do small setions at a time, and continue to verify alignment

Make sure you make a complete connection when pressing the fitting to the pipe. This will allow for a complete seal without any issues.

I bought it copper I use very little work but with pex, I did some work and the rings broke and I can't find any more to buy, now it's rubbish

This works quick and easy. Take care of a plumbing leak immediately. You can always come back later to replace a leaking pipe. This allows to patch the leak.

I'm very disappointed in the way this tool works. It doesn't crimp the fittings properly. It's squashes ( over-crimps) the center section of the viega fitting before it crimps the sections that are supposed to hold the pipe. This distorts the o-ring causing it to leak, even if you reposition the tool and try to re-crimp it. Plus, the fitting sticks in the die and very difficult to remove. I'm going to try to return it. UPDATE: I have played email tag with this seller many times asking them to send me another 1/2" crimping die which is the most used size. The other sizes work OK but they just don't get it. I was willing to give this tool another chance. I even offered sending the whole to back to them for an exchange. LOT'S OF LUCK if you have any warranty issues with this tool. They tried to throw me a bone by offering various amounts of refunds. Don't waste your money. Update: Months later still no response. Absolutely no warranty! If you have any problems with this tool you're on your own. DON'T BUY THIS TOOL!
