Take to bottle out at annual inspection!!

When you reinstall the bottle just call it "baggage".
I might be wrong, but I thought that is exactly what it was all the
time. I don't know of any glider with a certified oxygen installation,
so we all carry oxygen as "portable" equipment. As such, it does not
need FAA inspection and does not affect the aircraft airworthiness
anymore than a flashlight or handheld GPS you carry in the glider.
The problem isn't the FAA, but the DOT requirements. I'm not familiar
with the DOT details, but prudence suggests having the bottle tested
periodically, even if you can get it filled without the DOT stamp.
I avoid the hassle and expense of commercial filling by owning two
glider bottles, which gives me plenty of time to get one filled while
the other is in use. I fill the bottles myself from larger tank that
will allow several refills to 75% or more capacity. The tank is small
enough that I can easily carry it with me on extended soaring trips;
however, the two glider bottles are enough for a week of flying with my
EDS controller.
If you do decide to fill your bottles yourself, be sure to learn how to
do it safely and get the right lines/hoses/valves. Improper equipment
can lead to fires and explosions (been there, watched it done). It is
possible to do it wrong, but done right, it's easy and safe.
