UniweldRHP400 Nitrogen Regulator with 0-400 PSI Delivery Pressure, CGA580 Inlet Connection and 1/4-Inch Male Flare Outlet Connection

UniweldRHP400 Nitrogen Regulator with 0-400 PSI Delivery Pressure, CGA580 Inlet Connection and 1/4-Inch Male Flare Outlet Connection

Q: The advertized Delivery Pressure of this regulator is 400psi, but the delivery gauge shown in the photo shows a max pressure of 600 psi. Which is it?

When the first stage of the regulator is supplied with > 600 PSI, the output is limited to roughly 480 PSI in the fully open position. Also, the guy that said you wouldn't need to go that high for normal use is an idiot. Nobody knows what you will be using this regulator for.

Q: How is the CGA-580 fitting threaded into this unit? I want to take that out and use NPT as much as I can.

Purchase a LASCO 17-6783 1/4-Inch Female Flare by 1/4-Inch Male Pipe Thread Brass Adapter. Don't attempt to remove the existing NPT-to-flare fitting because it is sealed into the regulator assembly and you risk damaging the regulator.

Q: Will this work with argon

Yes it will work with argon. The regulator has a CGA 580 inlet connection and a 1/4" male flare outlet connection.

Q: I purchased this regulator and the yellow hose does not attach to the 1/4" flare, it is to small. The yellow hose fitting is to big?

You are not using standard refrigeration hoses. Sounds like your either using the mini- split adapter or larger vacuum type hoses. Take it by an HVAC supplier and they will show you the proper size.
