				Here's a question for you experienced DIY, experimental RV drivers.   I'm having hassles getting my little oxygen bottle filled for cross country flights in my RV7.  The medical folks take forever because they are used to swapping out bottles and mine has a different type of threads.  The gas suppliers and welding gas shops don't want to talk to me at all.  The FBO that fills it is not convenient and wants $50 just to hook it up.
  
 My question is:  Can I get the fittings to connect my little tank directly to my large oxygen bottle on my Oxy-acetelyne torch set and fill my bottle that way?  (Up to the pressure of my large tank anyway)   They have no problem filling/swapping that tank for me and the guy at the welding shop says the oxygen is the same anyway.

				It used to be that there were different grades of oxygen based on their moisture content (Aviation oxygen being the driest). That’s no longer the case. The way the oxygen is now manufactured, results in all oxygen being in the dry category. Oxygen is oxygen, so you may fill your portable bottle from your large welding bottle with little worry.

				Welding O2 is NOT the same as ABO..aviators  breathing oxygen. ABO is much drier to make sure there is no moisture to freeze  at altitude. Find a maintenance shop to fill it for you......tip the mechanic  and he will fill it in 5 min.

				Yes, you can buy an adapter.  Bought mine from Aerox, about $35.  I was told the only difference between the welding and medical oxygen is the cleanliness of the tanks, not the oxygen.

				You are going to get people telling you "welding" O2 is different than Aviation or medical O2. I doubt that is correct. I know someone that works at an O2 plant and they fill the medical and welding bottles from the same source. They make O2 to one standard. The only difference is when you buy "medical" O2 you get something that tells you it meets standard "X" with the other O2 you just get your O2. 
 
 Make your own informed choice but I and many others breath "welding" O2 and are not dead yet. Heck the air here in Los Angeles is probably more harmful than anything you get out of a welders tank. Just one opinion though.
 
 You can probably save a few bucks by going to your local welding supply place to get your fittings instead of "aviation" fittings. Tank your tank down there  tell them what you want to do and in a few minutes you will probabily walk out with what you need and save shipping.

				Aviation Consumer had an article in their February 2004 issue on this. As another listed posted, they found that ALL oxygen is generated to the same standard now. It's cheaper for the manufacturers that way. 
  The Aviation Consumer article details how to re-fill your oxygen cylinders at home. If you are a subscriber to Aviation Consumer, you can go online and do a search for this article. It's titled ROLL YOUR OWN OXYGEN.

				Mikey,
   
  Education is key to success in most fields... you may want to do a little more research to support your position.

				You can check out my fill setup here:
 http://www.myrv10.com/tips/accessories/oxygen/index.html
 
 I've been through my local Welding/Medical gas supply
 shop many times, and have spent lots of times with various
 gasses, dealing with these places for the Semiconductor
 industry, the technical Mixed Gas SCUBA industry, and
 welding.  Indeed at least at our local center, ALL of
 the oxygen filled comes off the same lines, and is
 all generated from the same Liquid O2 source.  There
 is no CO2/C0 worry, there is no "pumping" factors to
 deal with. It's just liquid O2 put into bottles, and
 it's all the exact same O2.  The standards that they
 work under become labeling standards, and in some extreme
 cases they pump the bottle to a vacuum before filling
 it.  I've purchased Heilum, and Oxygen, for use for
 deep diving, and have spent hours and hours using
 and filling oxygen for those purposes too, as Oxygen
 is used in decompression stops while deep diving,
 and air/oxygen mixes used for some of the other depths
 and types of diving.  So I had a real concern
 and verified it by going there and visiting their
 gas fill area personally.  I'd suggest you do that
 just for your own education...just tell them you're
 looking at leasing welding O2 and you would like to
 see how it's filled there, and then ask them what
 differences they have for filling medical O2...and
 if they hook up to the same supply.  I'd bet yes.
 
 That is not to say you don't need to use care in
 HANDLING the Oxygen.  I've personally seen O2 fires
 start, and things can get out of control in a hurry.
 So every single item that you're going to have O2
 flowing through should be both O2 compatible and
 O2 clean.  This isn't anything too extrordinary...
 they just must be made for the purpose and not
 have any greases on them.  Additionally, any time you
 open an O2 bottle, do it slowly.  I've felt the
 air rushing out of a hose from a fast-turn-on,
 and you'd be surprised at how hot it gets for
 that couple seconds from adiabatic compression.
 But just do it slowly, use real O2 hardware, and
 you will be just fine.  (oh, and don't smoke...but
 if you are a pilot, you probably can't afford to both
 own planes and cigarettes at the same time anyway,
 so it's probably not something you need to worry about)
 
 Leasing O2 bottles is a great way to go. Just
 least at least 2, or maybe 3 if you use O2 often,
 because the more bottles you have the larger the
 number of totally "full" fills you can get out of
 it.  2 would be good for the occasional user.  1
 probably won't cut it if you really want bottles
 to end up full....too much volume/pressure drop
 from the first bottle.  Then when one empties, just
 drop it off and swap them, and they'll charge you
 only for the contents...maybe $25 or so for a
 huge bottle.  I was lucky enough to have owned about
 25 or more large storage cylinders over time, so as
 I got rid of them I held on to 4 of them for use
 for my O2 for my aviation filling.  Then I just
 got a little hardware and it's been working out
 great.
 
 There is a lot of misinformation out there, and
 info that is from the old days of gasses.  But just
 go check it out for yourself.  It's easy to
 learn and understand.

  I'm having hassles getting my little oxygen bottle filled for cross 
  country flights in my RV7.  The medical folks take forever because they 
  are used to swapping out bottles and mine has a different type of 
  threads.  The gas suppliers and welding gas shops don't want to talk to 
  me at all.  The FBO that fills it is not convenient and wants $50 just 
  to hook it up.
  
  My question is:  Can I get the fittings to connect my little tank 
  directly to my large oxygen bottle on my Oxy-acetelyne torch set and 
  fill my bottle that way?  (Up to the pressure of my large tank anyway)   
  They have no problem filling/swapping that tank for me and the guy at 
  the welding shop says the oxygen is the same anyway.

				LOL!! 
 
 Has nothing to do with safety. Kind of shows
 how uninformed you are.
 Your comments about someone being
 being a republican are way out of line.
