Unscrew the assembly tool into two pieces: the ferrule
guide and the compression fitting.
6 Slide the compression fitting onto the longer, straight end
of the new liner with the threads pointing toward the end
of the liner.

with the recessed graphite end towards the compression
fitting. Slide the ferrule so that about 2 mm of the liner is
exposed beyond the ferrule.
8 Slide the compression fitting up to meet the ferrule.
Finger- tighten the ferrule guide onto the compression
fitting.
9 Unscrew and remove the ferrule guide.
10 Slide the compression fitting off the other end of the
liner. The ferrule should now be set with 1 mm of the
liner exposed. Check that the graphite within the ferrule
is flush with the top of the metal collar.
