Flaring tool
Flaring tools consist of three main components: a metal bar with holed presets that fit different pipe or tube sizes, a screw with a handle that goes into the pipe opening to expand it as needed, and a simple metal piece that fits into the handle and enables rotation by the user.
Considerations
Flaring tools are also known as cutting tools, because many kits add pipe cutting functionality. It's important to remember all of these tools only work well with soft tubing, mostly copper. They can't adjust harder metals like iron, this set of flaring tool also comes with a set of swaging tool to expand the same tube size in order to be fitted together before welding. This product is a full set of flaring tool.
Swaging tools use pressure to expand or stretch the end of a piece of copper tubing so it can fit over another of the same diameter and make a permanent brazed connection. ... The types of swaging tools for copper pipe include spike-shaped punch tools, manual tube expanders and feed screw tools comparable to flaring bars.
