O2 filler port adapter

[BravoWhiskey]

I went to fill my O2 for the first time since ownership, but the O2 filler station did not have the right adapter and I did not have one in my new owner box of random stuff…

I have been trying to find out what this adapter is so I can get one to keep on board in case I run into a mismatch when traveling.   I don’t see it in my books anywhere.  I’m thinking it’s the CGA 540?  Any particular piece work best for for most applications?

Check with Danb about his fitting. I filled his O2 tank and I noticed he had an unique adapter that I attached to my CGA 540 fitting.

@BravoWhiskey I think it's a Aerox CGA540 to Scott adaptor  https://www.aircraftspruce.com/catalog/pnpages/13-04538.php 

But hopefully @Danb can confirm

That's the one I use.  I came with the filling kit I use at our hangar after the FBO discontinued O2 service.

That’s it. What was different was that on small O2 bottles (unless they are pure medical bottles) they have a male CGA 540 port. My transfill set up has a female CGA 540 that connects to the bottles directly. I had to rig up a conversion adapter to make it work with Dan’s adapter.

FWIW,

Welding shops usually stock all the high pressure fittings. They will have all the CGA and NPT fittings. They won’t have the Scott fittings.

Thanks.  I’ll give this a shot

I’ll get to the hanger this weekend if Joe let’s me in  take a picture of it. It looks like the one pictured

You are looking for a welding supply shop, not  welding shop.  I used the local Praxair distributor to get any of the western enterprises fittings.  You might have to order some, but its worth the wait. http://westernenterprises.com/wp-content/uploads/2018/10/Industrial-Catalog-2018.pdf

These are my go to guys for all oxygen fittings, its not very expensive to build up a couple of hoses (even long ones) to fill your airplane and portable bottles.  Remember, the longer the hose, the more gas you lose on every fill.

And they have some neat converter and adaptors, it's feasible to make hoses with one fitting for the oxygen bottle and one for the airplane side without multiple nipples, adaptors, bushings etc.  If you can read a catalog, you won't have much difficulty.  There are fittings here that will connect directly to the small and large size scott fittings on the airplane, and also the standard CGA540 bottles.

Then you can keep a nice set of hoses in your plane, keep them clean and either fill yourself or lend to the FBO you are visiting etc.,  I also bought a set of wrenches specifically for my oxygen filling kit to protect my fittings.

Great shared O2 details!

Go MS!

I also use a dedicated (clean) wrench for my oxygen system. I prefer the Mountain High Scott adapter - very similar but has about 10 inch copper tubing between adapters.

Be sure to verify tank is not expired on hydro test, or otherwise timed out, before filling.
