Non-sequitur because you inverted the thermodynamic process.  If there was a gasoline line strapped to an electrical wire that would be very close to what is being done here.  There is a reason why the FAA requires 6 inches of separation between an electrical wire and an oxygen line.  Not mention the oxygen line draped across the edge of aluminum plate and steel tubing without chafe protection or standoffs.  

I would not ride in it and even the OP expressed misgivings. When you have mis-givings, listen to that little voice. 

Thanks for posting this.  FWIW, I agree 100%.  I deal with the tubes always being in the way, and it's no big deal.  I will not route the tubes into a semi-permanent, out-of-view installation.  there are too many things that could chafe, disconnect, or other go bad without eyes on them.

YMMV.

Hmm, would this be the quote where the OP expressed 'misgivings' ?

"Never had an IA comment on it, and at least two have worked on the plane since install.  I almost didn't post it, because I figured someone would be along to tell me it's illegal and will cause my plane to explode, somehow,.."

His plane won't explode, it will just burn like a Roman candle. Once an O2 line is breeched there is no telling where it will find a source of ignition, which interesting enough can be the breech point itself. (Ask the NTSB because they could not identify the ignition point on Delta 1558 at KSLC)

It's a fair enough point.  I'll look into re-routing the O2 line away from the electrical wires, probably easily done, and I appreciate the thoughts.  You also could skip zip tying it at all and just plug and unplug the hose every time and run the hose across your lap.  But my goal in tying it up out of the way was to protect the hose as much as convenience.  With them strewn all over the cockpit they're always in danger of getting kinked, stuck under a seat rail, unplugged, etc.

+1 for the 02D2! Despite what the charts may say, makes my port tank run MUCH longer than oximizer. And to @donkayes point, I too wondered “how will this regulator know what amount of flow is right for me?”  Since you can’t adjust it yourself, it forced me to tweak my breathing technique just a tad, which solves the issue without simply blowing more 02 out of the bottle. Lots of information about efficient gas exchange techniques in breathing found in the freediving world.

The tweak is, if you aren't getting enough in the N or one of the D settings, use one of the F settings.

Nope.   Totally does follow.    Thing that can get hot next to tube carrying oxygen.  And your point was the temperature rating of the 'thing that can get hot' was higher than the melting point of the tube.  The tube is polyurethane, not vinyl, BTW.  

Anyway, I totally agree that fear is an acceptable alternative if understanding of a situation is not possible.

I’m not sure what others have found. But using boom mic cannula I’m usually D10 up to about 16k or so. If I’m using a cannula at 16-17+ I find that the pulse duration and my breathing pattern (depth/frequency) makes one of the face mask setting ideal for where I like to keep my SPO2. 

I have a medium mountain high face mask and F1 is perfect at least up to FL250. but the mic is really horrible.  

Has anyone used a face mask without a mic and just used a razor to cut a “X” in the side wall to push their headset mic through?? I am curious how that sounds and holds oxygen. Would be cheaper than a mic mask as well!

So I take it you disagree with the FAA recommended separation requirement?

Nope, I don't disagree with that at all.

$1995, brand new.  You send a copy of your pilot certificate instead of a prescription.  This is the place that most people on BT have been buying from.

Damn should have bought one 6 months ago when this was posted the price has gone up $1000! Inflation is out of control.
