Hey guys, looking to pick up a new bottle for welding gas. My current bottles and regulator are CGA-320. A friend of a friend has a new-ish bottle for sale that has a CGA-326 valve. Is it safe to use my '320 regulator on the '326 valve? (Does it fit?)
Check out the CGA guide here....Paul
CGA-320 is listed as being for C02, and uses a sealing washer.
CGA-326 is listed as being for Nitrous Oxide.
If the bottle is for nitrous they won't fill it with CO2.
The two different fittings will not intermate and your regulator will not fit that tank directly.
Don't use nitrous oxide as a welding gas. Bad things will happen.
