Cutting/aring the pipes
1. Make sure that you have the following required tools: pipe cutter, reamer, flaring tool and pipe holder.
2. If you want to shorten the pipe, cut it using a pipe cutter ensuring that the cut edge remains at 90° with the side of
the pipe. Below are some examples of correctly and incorrectly cut pipes.
Oblique
90°
Rough
