I had to swedge a 3/8 steel line and piece it together with another. I have never used this tool before and found it did a great job for me. And I highly recommend it for somebody trying to do the same procedure. I'm sure it is easy to use with soft copper tubing. In my situation, I was using a harder steel tubing, so I had to take my time bit by bit doing a little at a time to avoid cracking the steel tube. The tool is sturdy and works very well for the price

This is an inexpensive tool that requires time and patience. If you proceed slowly and rotate your stock, you can swage tubing almost as good (NOT as fast) as a hydraulic swaging tool. It takes patience and practice.

Works like a champ. A must have. Saves the day all the time.

Works great, but you must stretch slowly spinning around the pipe to avoid ripping the copper.

Compact and as long as you gradually go around expanding the copper pipe equally with medium force you should get the job done fast and right. I work in hvac and use it everyday.Less effort.

I seen a few complaints with users complaining about the flare being too big when complete for the brazing specs with 15% silver. I personally did not have any problems with what I had on hand for test swaging. With any new tool, practice makes perfect. I tried 7/8; 1/2; and I think 3/16. It took some work on the 7/8 but turned out perfect, much better that the swaging drill bit does on 7/8. The drill method on 7/8 imo deposits too much debris inside the tube. On the smallest size it will Crack if you dont go slow but will come out perfect after doing your test swaging. The tool feels built well. I would recommend this tool for light maintenance use, not a tool i'd trust to use everyday for heavy industrial.

So I'll start by saying I'm an appliance refrigeration tech doesing sealed systems. Almost all appliances are 3/16, 1/4, or 5/16 copper lines. The 3/16s are mostly just valves or inserts for the 1/4 so you don't need to stretch them. 1/4 lines are so thin now days even a medium amount of pressure with this tool with split the line faster than you can blink, GO SLOW. also it only stretches about 1/4" deep into the line so getting a good fit can be tough. WORK CARFUL, GO SLOW, AND BE MATHODICAL or this tool isn't for you.

I do A/C HVAC stuff. Why did I wait so long?Hard plumbing copper is not recommended.....a/c copper is great. 5/8, 3/4 yes. Swage replacement for sure. Evap coils and lineset stuff for my application.

Smaller pipes than what is required are often a problem when they need to slide inside larger ones. Bull-nose pliers are not the best way to enlarge them, but this expander is!
