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.
