Tank adapter question

Just bought a 30 minute MSA SCBA tank, & will be filling from my compressor- the fill whip on my compressor terminates with a female Foster fitting.
The tank valve, pictured here, is confirmed by MSA website to be CGA-347. I have a male CGA-347 to male Foster adapter, but need a female CGA-347 to male Foster.

So what I need is one of these:

Correct? Seems simple enough, just want to confirm with the AGN illuminati that I'm not missing anything.
 
I would suggest this one: https://www.ebay.com/itm/2552967602...PVzi0eLSdG&var=&widget_ver=artemis&media=COPY
It's got a hand tight nut to the CGA347 threads instead of a wrench tight nut. Just remove the hose from it and install a Male foster where the hose was. IF you install a one way foster you WON'T be able to fill your gun from the tank as the one way won't allow it. That why I, personally, have 2 CGA347 adapters. One with a one way foster dedicated ONLY for filling tanks and one with a fill whip for filling guns from the tank.
