Thanks to Tim and Stu8 for the link and advice. I ordered a cylinder
from Cramer Decker Medical as a spare for my glider. I will give a report
when it arrives.


Out of interest why would you require a spare cylinder? I have just
fitted a MH system with a German sourced Steel cylinder (3000 PSI) to
my Cirrus and my understanding is it will provide enough 02 using
nasal cannula for many many hours use.

Our Club has a refill facility for members that is free. so we should
never have an issue.

Maintaining the O2 system at the home field and knowing that many pilots like to do "safaris", why would you not own two cylinders?
Sometimes the truck with the new cylinder for the manifold filling system doesn't arrive. And nice to have one to use while the other is getting a new "Hydro".
