Do the Regulators used for beer gas (25% C02 and 75% nitro) have a female or male fitting on them? The nitro bottles all look to have female treads, and the regs male....is that correct? Thx
Depends where you get them. My welding supply gave me a tank that had the cga320 like the co2 tanks (male threads). But if the tank has female threads than its the 580.
