   A Fantastic Tool That Takes My Tubing Work To the Next Level!

   Hydraulic Tube Expander or Swaging tool is sold as a HVAC tool, but it has many other uses. I do a lot of classic car work we commonly make and use custom period correct copper fuel lines, just like the originals were. I had tried some other manual swaging tools that use a bolt to do the work and never liked the job they did. This setup uses hydraulics to do the work with 6 way expanding dies for each size for making a nice uniform swag that can be fine tuned to fit the tubing you are using. The kit comes with everything you would need to get going, including the expander tool, the 7 heads that come in common tubing sizes from 3/8″ up to 1 1/18″ of an inch covering a wide range of sizes commonly used in cars and trucks. The 3/4″ size if great for making custom heater hose solid line replacements that make your engine bay stand out! Just be sure to use a short section of rubber or flexible tube somewhere in the line to allow for engine movements!

   If you are into hot rods, this is for you. It works well to let you create your own custom fuel setup for the engine bay. I have used it to do several 3×2 carb and manifold setups and it really has elevated the level of my work. If you learn this tool well, you can make your own fuel manifold/distribution blocks out of a size or two up of copper tubing, get creative with it! I like to use a double tube style joint for the outlets, where I will drill 3 holes in the manifold pipe with one to feed each carb. Then I make my carb lines completely with all bends and add the short pipe I describe later, as well as the flare fitting, needed to fit the carb inlets only and feed them all into the pipe manifold, cutting with enough extra length for them to sit on the bottom inside of the manifold. before brazing keep the pip you slid over this end as far away from the heat as you can. I then braze each joint and let it cool. For the short pipe, I cut a short piece of tube about 1 inch long, and use the the expander to make it fit tightly over the tube I will braze in. Cut the bottom of this short pipe to match the manifolds outer diameter, and slip it over the line before you braze! After the joints have cooled clean them well and clean the tube up to the height of what the short pipe will cover. The slide it down flush to the pipe and fully braze this joint, from top to bottom. After it is all cool I use a drill press to drill out the pipes in the manifold leaving it now double walled and brazed on. A very good way to keep a really clean look and not use any flares or unions!

   This swaging tool is as good as you could expect for $80. When I received it, it did make loose swages but I took the set screw out of the head and backed it off. With a little trial and error I figured out that 1 1/4 turns from the bottom was perfect then replaced the set screw. The ram tends to get stuck so that it doesn’t want to back out when the pressure is released. A drop of oil on the ram fixed that.

   Also, is you try to use this or any swaging tool on rigid copper, the pipe is going to split. Soft copper only.
