I am looking for a replacement Qxygen cylinder for my ASW 28. It is
the weird one almost the same size as a "D" bottle but smaller in

REE16.6 Which is the cubic ft capacity.-

The luxfer M15A (OS415T)advertised here will fit.

Scott, do you have any input on the Luxfer carbon composite cylinders
working in aviation use, i.e. gliders? They appear to be medical O2
bottles, but I don't know if that makes a difference. The dimensions of
the OS415T, at 4" diameter, just could work in my LS-4. I'm searching
for a light-weight bottle.

Best Regards,

Todd

I believe (not claiming divine awareness)General Aviation O2 cylinders used in the U.S. are regulated by the U.S. Department of transportation. if you buy or use a cylinder the responsible authority is D.O.T, I have bought and used these Luxfer cylinders in my glider after passing a hydro test. these luxfer cylinders are amazingly light and have a reasonable capacity. the downside is the 15 year max life. check with your A.I. or A&P (standard or experimental)
I'm holding one in my hand filled to 2200 psi, it weighs 4 lbs 3.9 ounces
Good luck

Eastern Sailplane used to always have a stock of )2 cylinders that fit. Have you tried Eastern or Williams?
