Poly-Flo Plumbings and Fittings

I bought a Dynon pitot/aoa heated tube. I intend to route the aluminum tubing that comes out of pitot tube to poly-flo fittings. For those of you who did this, can you please tell me the transition components from the 3/16" Al tube of the pitot to the poly flo tube?

Thank you
Omar

Lots of ways to accomplish, here's one way:

266-N Female Connector (1/4 - 1/8)
AN816-3

Walt is correct, that is one way.

I ordered a female NPT - to "polyflow" from Avery I think.
Purpose was "minimalist" construction (2 piece vs 3).

I had already assembled a 3 piece conversion with a standard male npt to plastic "polyflow" tube fitting and an AN union and an NPT to 1/4 flare.

Surprisingly, the 3 piece assy was lighter than the 2 piece so I would not go to a lot of effort to buy the female to polyflow adaptor. The female NPT to polyflow fitting was brass and really heavy.
