with the side of the pipe. Refer to the illustrations below for examples of edges cut correctly and incorrectly.
3. To prevent any gas from leaking out, remove all burrs at the cut edge of the pipe, using a reamer.
4. Slide a flare nut on to the pipe and modify the flare.
5. Check that the flaring is correct, referring to the illustrations below for examples of incorrect flaring.
6. Align the pipes and tighten the flare nuts first manually and then with a torque wrench, applying the following torque.
