Hi guys, since today i always used aluminium bottle as chamber in my pneumatic canon like this one:

But it's not a erfect 3/4" npt so it 's not perfect proof and now i want something perfectly proof so i need a chamber with a real 3/4" connection. or a 1" i could use a reducer. so do you have any idea? something in metal will be more appreciated!

Sorry, I don't quite understand what you mean by "perfectly proof". You were trying to say perfectly right? Could you Please spesify... Darn language barrier

yeah i'm sorry for my poor english. But yes perfectly proof mean that the under pressure air in the chamber stay in it. so perfectly proof means proof !

Perfectly air proof or air tight is how you should say it. If you use epoxy you can defiantly get it to hold air, that's how i did it for my fire extinguisher. You can also use pipe and fittings sold in hardware stores

Pipes are heavy and don't offer big volume... What's the size of the thread in an extinguisher? is it all the time the same?

I would suggest a 3/4" pipe nipple, and then you cover the thread in epoxy, and screw the pipe nipple in.
