Bottle Valve question
I bought a Nitrous bottle for $60 a few years back, and it was stripped down so i don't know what brand of bottle it is(i think it is a Zex bottle), so i painted black and its fine now. The problem is i want to run a blowdown on it and i am not sure if the fitting i need is an external or internal blowdown fitting. I have about 4lbs of nitrous in it and didn't want to waste it. I just want to get the right fitting when i do use up the rest of the nitrous so i can put the fitting on. Here is a pic of the valve. Thanks Ryan
