Hello all,

 

I am needing to run some hard line tubing for an oxygen system and I am wondering what type is correct. I looked in the FAA publication and it calls for some sort of copper tubing. I would suspect that aluminum tubing would work just as well if not better plus I likely already have it. I am wondering what is the correct type and what inside diameter someone would suggest to connect directly to the oxygen tank itself. The tank has a maximum pressure of 2014lbs. Would the 5052 stuff that is used on the Legacy landing gear system good enough or is something stronger required? What about 6061. I see that is another type that is easy to get my hands on.

 

Thanks for any info.

 

Matt
