Connecting spunding valve to sanke coupler?

So I am getting redy to purchase the parts for a few spunding valves and I am hitting a snag on one point. I have the pressure reliefs and gauges sourced (both 1/4 npt), but I don't know the best/most secure way to attach the valve to the coupler. I know some people have used 1/4 flared tailpieces, but how do these connect to the valve parts which are NPT. Is there a cheap source for female npt, flared run tees? I also found some 1/4 Tube O.D. X 1/4 Pipe Thread Inverted Flare Male Connectors:

would those work to connect the flare to a normal 1/4 female tee?

Thanks in advance for the help/sourcing!

Any suggestions before I pull the trigger?

So just in case anyone else is looking for a piece like this, chicompany has them in ss for a pretty fair price:

It's been a while since you posted this. Did you complete the build?

I thought sanke couplers were an odd size like 7/8-14 bpt? Or am I missing something?
