QuickSwap end
1 Insert the end of the column with the swaged ferrule into Fitting 2 on
2 Gently push until the column end bottoms out. Follow with the nut.
3 Finger-tighten the nut. Use a wrench to tighten the nut about 15 degrees
If the ferrule is not over-tightened when the column is installed in QuickSwap,
it should provide an air-tight and leak-free seal through many removals and
re-installations.

will be inaccurate.
