Rob and Bob -

We also used those quick disconnects that Blue Mountain uses for all of our connections to the boxes in the panel. The company is Colder and they have a website that has all of the products. They even had a small diameter male fitting for those small tubes to the AOA box.

The manifold idea would even make it easier.

We also used several fittings of a line that McMaster Carr carries for some of the routing of the tubing and for static line drains. They use the 1/4" OD nyloseal tubing and are push-in type that are used for fluids and gasses in the commercial world. I wish now that we had used them for all of the pitot and static system - instead of those darned compression fittings. They are easier to assemble and disassemble and are more compact. You can even get then in 45 degree or 90 degree swivels; which made the connections to the autopilot one heck of a lot easier. I have used the Colder quick disconnect fittings in the CO2 system in my beer refrigerator for years and have had no leaks.

Rob -  If you want the item numbers from Colder and McMaster Carr, let me know and I'll look them up in the parts file.

Cheers,

John

...As I complete my panel installation this winter, I will make sure that
there are electrical connectors allowing me to disconnect the panel for easy
removal.  Haven't figured out how to disconnect the pitot-static and vacuum
lines -- I'll probably just pull them off somewhere and buy another
pitot-static check when I put it back together.


Due to the large number of instrument/etc that use pitot and static sources
on our IV-P panels, I made manifolds out of Delrin and mounted them to the
side of the radio stack frame. I then connected all instruments with nylon
fittings and nylaflow tubing. This method provides only one pitot and one
static line that needs to be disconnected to remove the "complete" panel. I
used a "standard" nylon compression fitting for this.

Another approach you might consider is to use the high quality
nylon/stainless quick disconnect fittings used on oxygen systems. Mountain
High, among others uses and can provide them, but I don't know the original
source. BlueMountain Avionics (EFIS One) uses five of these to connect their
computer to the various air sources. They are quick and easy to
attach/disconnect, and have proven very sturdy and leak resistant to date.
