Co2 tank threads!

iPaintball · Fri Apr 13, 2007 2:30 pm

I'm considering using a 10 oz paintball Co2 tank as a chamber for my in-the-works qev marble gun. I removed the pin valve, but I can't seem to find the thread size of the actual cylinder anywhere! If anyone knows the thread size, please tell me! I need help!

CGA 320 i believe

Edit... yes it is
palmers has an addapter to 1/8

They also have a stainless version... but its double priced

No. CGA 320 is the the thread size for the outlet threads (ASA).
That adapter screws into a bottom line. I need to know the threads of the actual cylinder...

Take your pin valve drill it out, and tap it.. with a NPT thread

Or email Mr.Palmer... or Doc from docsmachine.com

one of them will deffinalty know...
or you can email one of the airsmiths at PTI. paintball training institute.

you could build a sweet hybrid with one of thoose bottles that or if u make a pnumatic run it off unreged scuba air thoose c02 tanks are made to hold 3k psi at least cause the burst disk on the pin valve pops at 3k

why would u make a hybrid out of a c02 containtor...and using unregulated scuba tank is incredibly stupid..

A co2 container would make an excellent chamber for a hybrid spudthug.
Why wouldn't it?

The size is 1/2" BSP or the British national pipe thread. We use BSP fittings here, not NPT. 8)

you would make a hybrid from a co2 tank because it could probably take a 50x mix without blowing up and using unregged scuba in a gun with a metal chamber rated to 3kpsi is not stupid seeing a completly full to the brim scuba tank is only 3k psi
