Dynon Pitot tube plumbing
- How fitting 3/16" pitot aluminium tube with 1/4" nylon tube ?
2 - I blow through dynamic pressure hole to identify the 2 tubes (in water). I 'm surprise in finding air bubbles through the threaded hole.
Is this a leak in the pressure line ?
The Dynon answer:
- 1. There are small drain holes in both pitot and AOA lines that are not intended to be sealed. They are not just the holes you can see from the outside of the tube, but are inside the chamber and are not accessible to seal for your leak test. We recommend that you perform a test just above the probe for the rest of your system.
- 2. You can use a reducer from one diameter to another (ok with nylon tubing) to do what you need. There is one that we recommend that can be found at Aircraft Spruce – 3/16 to 1/4 reducer P/N: AN919-2D. You can get this one or something like it.
Let me know if you have any other questions.
