Cutting/Flaring the Pipes
1. Make sure that you prepared the 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. There are some
examples of correctly and incorrectly cut edges below.

3.
To prevent a gas leak, remove all burrs at the cut edge of the pipe using a reamer.
