It is not Van's static kit. The two ports, on the outside skin are about
silver dollar size with four rivets each.
The tee for the ports only sits about 2" above the ports.
Sure would like to convert to plastic to make all the connections easier
All comments and direction greatly appreciated.

I take a short piece of the tubing I want "coupled" to the local big box store (Lowes) and select tubing off the shelf that is a tight fit. The vinyl tubing is protected from UV in our installations so service life is measured in the tens of years. But you can also use neoprene tubing from the local auto parts store.
Also, ice maker nylon tubing works very nicely for running AOA and pitot-static lines. You can use the "tubing coupler" or if you want to go fancy, the push on connectors found next to the ice maker tubing work just fine.
This is low-tech, no need to make it more complicated than necessary.

Thanks Sam
Being new to building airplanes, one's mind thinks everything is special
to an airplane and highly controlled.
I will learn as I progress.
Thanks again

You could have avoided the alum tubing and the coupling by just bringing the plastic line right up and flaring the end just like the alum and use the same collar.

It's probably overkill, but I found these bulkhead fittings at Automation Direct that are 1/4" plastic tube to 1/8" NPTF. I plan on mounting two of them in the rib between the pitot/AOA tube and the bellcrank bay in the left wing. I'll then use an AN816-3D nipple between this fitting and the aluminum tubing from the pitot/AOA.

I'm gonna divulge a little secret that will make safeair mad at me:
http://www.poweraire.com/instant-fit...ca94e5869b1fd7
http://www.poweraire.com/fittings-in...-c-21_573.html
I use them for all my pitot/static runs, as well as all my shop air (it's the same stuff as the very spendy "rapidair" shop air plumbing kits). They're pneumatic fittings and they're good from -29.5inhg vacuum up to 150psi pressure. Plenty adequate for anything you want to use them for on the RV
