Valve for 425 G CO2 Bottles for Soda Machine

This is a valve for carbon dioxide bottles for soda machines. It is without the refill trap that is supposed to prevent self-refilling of certain brands of carbon dioxide bottles. At a certain refill pressure, valves with a refill trap are closed. This is to prevent self-refilling from a larger carbon dioxide bottle. The valve also fits in 73680, a pressure hose with a manometer that allows you to connect large carbon dioxide bottles to your soda machine.
