Retrofit O2 system

[231LV]

Recently, I found 2 of the 4 O2 ports in my plane will no longer accept "bayonet" plugs. There doesn't seem to be anything impeeding them but they simply will not slide all the way in. In order to replace these ports with new ones, I am trying to locate which manufacturer made them. The O2 system was installed as a retrofit kit in accordance with Mooney 870024 drawings. The log book entry simply states "O2 system installed IAW Mooney factory drawings 870024" back in 2002. I suppose I coud contact the shop if they are still around and see if they have any records on the install. Failing that, is there any other way of determining what system was installed prior to pulling the plastic ceiling panels and removing the ports?

You might ask your favorite MSC if they can get that drawing, which will certainly have a bill of materials for that installation.

They are probably the Scott fittings (#38)

Perfect...those are the ones! Thanks very much!

Definitely use caution with matching the ships ports to the other O2 parts...

There are a few threads around here that discuss the challenges... and the difficulties in identifying what you have...

Mixing parts can be hazardous if used...

Best regards,

Thanks....yea, I wouldnt order them without looking at the serial number on the port first....now on to removing the ceiling panels!

[231LV]

OK...so I pulled the ceiling panel off and removed the 2 port blocks (2 outlets per block) and checked them.....they are really pretty simple in function and design. Other than replace the O rings for each port, everything else looks fine. Im wondering whether anyone has a suggestion of where to locate the correct size O rings....unfortunately, they are not included on the drawing schematic Lancecasper provided. Failing something else, I can measure them and order several sizes which appear to be correct and just try them on for fit (and leak test).

call these folks - they have seen it all : https://aviationoxygen.com/

OK...so a pretty easy solution....simply replaced the O rings in each port....a couple were cracked which was allowing O2 leaks. Kind of fun removing the ceiling panels to see how everything  goes together. The plastic is old and brittle but will use Hector for Ultraleather when the time comes.  Next up...putting the new JPI 900 into the panel. I have the unit sitting here waiting for my mechanic to fit me into his schedule.

I have several news ones for you, Aerodon
