3.2.2 Creating the arings
- Cut the pipe to an appropriate length with a pipe-cutter
without damaging it.
- Carefully deburr it, holding the pipe pointing downward
to avoid introducing lings into the pipe.
- Remove the ared connection nut situated on the
valve to be connected and slide the pipe into the nut.
- Proceed to are it, letting the pipe protrude out of the
aring tool's tube.
After aring, check the state of the working radius (L).
This must not present any scratches or signs of
fracturing. Also check the dimension (B).
