I need a "fitting" for an aluminum Cyl

[Bobalos]

I have a small 2.5 Lb CO2 bottle that Im using as an air tank & managed to break the fitting that goes into the top of it. 

I believe that its a 3/4-16 UNF thread.  what Im after can be just a plug & I will drill & tap the female threads into it. 

I dug around McMaster & Grainger & could not find what I was after.  I tried home brew sites & stuff like that & am still coming up dry.

Any suggestions.

My mind goes to a welding shop. Specifically one that does cylinder exchanges. Maybe they would know what you need?

Probably best for same day sale, but they are available online. 3/4-16 is also the thread for a -8 AN fitting.

Just go to local hydraulic or hose shop, that's standard, a 3/4-16 is a JIC #8 fitting
