I have a vending trailer with two forty pound propane tanks piped into a single line. This regulator handles these great and it’s adjustable for my Funnel Cake cooker. Yes, you need to adjust it with a gauge to set it for the equipment your using but that’s the great thing. I will support the equipment your using.

Regulator was a good buy and it was delivered on time as promised. Works well on my new propane tank.

Had to replace the same brand and model that failed after 4 years, mostly under cover from the elements. Was selling the RV and would not feel right giving the clueless buyer a cheap, foreign made gas regulator. Rego will tell you that their regulators need maintenance but it was easier to buy a new one rather than try for warranty service. Despite this I still think Rego is better than other options when it comes to safety and longevity.

They had exactly what I was looking for.
