Mechanically Formed Extruded Outlets:
Preliminary Requirements

Be sure to have all tool kit components handy (Figure 13.2). They typically include:

The tee-forming power drill outlet pulling tools and the manufacturer's instructions for their use and proper application.

A tube end prep tool that forms the end of a branch pipe to match the inner curve of the run tube while simultaneously pressing two dimples in the end of the branch tube. One acts as a depth stop and the other for inspection of the joint after brazing.

Be sure the pipes (run and branch) are drained and not under pressure.
