The Dynon pitot and AoA lines are small diameter soft ally tube, so I decided to limit vibration and work hardening by supporting the fittings further down with a silicon washer inside the pitot mast. This will be pushed almost all the way to the bottom of the mast during installation and is trapped between the tube nuts and a larger adapter for the press-on line couplings.
While I was at it, I JB Welded the press-on fittings into the adapters I had previously turned up on the lathe.
