Hangar Project - Oxygen Filling Setup

[Pinecone]

Hydro testing is easy.  Remove the bottle, send out for test, reinstall.  Mine was just done last annual.

So.....    I apparently can't click on the correct things, and the part I ordered that I thought was a CGA-540 Male to Scott 9/16-18 Male was actually the wrong gender on BOTH sides.    What the heck?    

So I've bought the correct one, and test-fit everything, being careful to not touch anything with my hands that will be in contact with the pure O2.  

I also bought a CGA-540 to Puritan Bennett adapter for my portable bottle.

Next step: Get my current non-ABO bottle exchanged for a full ABO bottle and refill my onboard tank.

Unfortunately I had very poor oxygen management on my last flight and depleted my onboard O2 to about 100 PSI so it might be worth going ahead and buying a second bottle so I can cascade them.   Or not.

Once I've got that done and have actually done a refill I'll take some pictures and post it here.

ONE MORE TIME, there really isn't ABO.  ALL O2 these days comes from liquid oxygen and is 99.99999% pure O2.

While there may be no physical difference between the products labeled as ABO and other oxygens, there are legal differences.

At the very least, you can buy ABO and other industrial oxygen products without a prescription but you must have a prescription to buy medical oxygen.

 

Regardless, I'm not planning on breathing from the tank that I bought second-hand from a random dude off of craigslist, when he said the last time they looked at this tank was about the 2008 economic turndown.   And I guess it remains to be seen how much if any difference there is in the price between ABO and other industrial products.

Then have the tank inspected.  But it is the same oxygen.

LOTS of articles on this.

Yes, I know the product is the same.     

But also, there is no place around that will refill a tank for me.  I have to exchange the tank.   And they'll take care of any purging and testing of the tank.   

So I'm going to have the tank exchanged because what's in this particular tank right now might be someone's homebrew oxygen concentrator to a compressor made out of an old VW engine that they previously used for chlorine, ammonia, and the covid virus.  

[Pinecone]

OK, I can see that.

But I would just exchange for a O2 tank for welding and not look for ABO.

Industrial Oxygen: $65 exchange

ABO: $250 exchange, and they can get it late next week.

Medical Oxygen: Unknown; they won't quote a price without a prescription.

So I refilled my plane and portable today.

Looking forward to using O2 a lot more often.
