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
Should be a CGA (Compressed Gas Association) 580 fitting.
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.
So there's no standard on this?
