Bayou Classic 7850, 0-30 PSI Adjustable High Pressure Regulator, 1/4" Inlet and Outlet

I did a bit of research and this was the best high pressure regulator for the price. The pressure is easily adjusted just like a air compressor regulator. I do not have a pressure gauge on my system but it seems to be a pretty fine adjustment. 1/4npt fitting might be a little too small for some higher flow applications but it does have enough flow to keep up with an outdoor burner with 3 large burners. I am able to boil the 6.5 gallons of water for my beer wort very quickly.
