Thanks Willie!!!

No you won't have to specify the fitting. The CGA (Compressed Gas Association) designations are standards for each of the gasses being used.


Think of them in terms of electrical plugs and outlets. There are different types and sizes for a reason. You can't plug a 20 amp drill press into a 15 amp wall outlet. It won't fit. They are designed that way so you can't 'accidently' overload the circuit. Yet, you can put a 15 amp plug into a 20 amp outlet and it will work because the circuit can handle the lesser amperage.

The CGA fittings are designed to do the same thing. They keep people from putting the wrong type of regulator on a cylinder that contains an incompatible gas for that regulator. That is also why fuel gases fittings have LH threads and inert gases have RH threads. Things can go boom when you accidentally mix two different gases that shouldn't be mixed. The standardized fittings help to prevent that.
