Not sure what you are asking. You want to attach standard pipe thread to an ASA thread. ASA being the same as a regulator, remote hose fitting etc?
The fitting you are looking for is a Male or Female ASA thread?
Preferred pipe fitting thread?
Remote hose fittings should work. male of female fitting. The pipe fitting is 1/8" NPT pipe. Go to standard pneumatic quick disconnects.
Ditto the hose on the END of a remote is 1/8" NPT pipe.
New or used bottomline fitting is female ASA and 1/8" NPT. Some of the after market ones allow easy attachment of a grip and stuff.
Here is a pic for my air tank plumbing through a reg. Uses an old remote hose to screw the reg into.
What is the volume of your air chamber and what psi does a standard 12 gram generate. A LOT of us have been curious about that.
If you have a given volume for a 12 gram to expand into to produce a give psi, then a little math will allow us to generate any given PSI needed by adjusting the size of the air chamber it expand into. Got the info? Do us a favor and find out for us. Probably have to put a pressure guage on it any way to be legal at most fields. Calculate or measure the volume. Fill with water and pour out into a measuring cup
Tanks a Lot.
