I'm attaching a pic to illustrate parts of the regulator. When you turn the M tank on, the demand valve will be charged and ready to use. The mask flow control has no effect on the demand valve. You will leave it on "0" unless you use the O2 mask rather than the demand valve. You will need an adjustable wrench of sufficient size to attach the regulator to the tank and the demand valve to the regulator. Ensure the tank valve is closed before swapping regulators.

I think I have found a better deal for you. HERE This option will give you what you need plus a barb fitting for the mask as well so you can use either. Glad to help.

Usually Amazon has some, but it appears that right now that none are available there. You can configure one with a DISS fitting at WT Farley Here. E tanks regs are easier to source. I've also found an adapter that may work but am waiting on the proper seal to make sure its something i can recommend. There may be others but ATM I can't locate any. Ill keep my eyes open.
