I replaced a leaking regulator on my RV 30 gallon propane system. It was leaking where the upper and lower sections are pressed together. This unit is sealed by four nut and bolt fasteners that will hopefully avoid a similar leak in the future

Works great for my 13kW LP Generator.

Keep the 1/4 inch LP hose will not work other than that is good

Need adapter for the 1/4 LP hose keep the adapter from the old regulator

Travel trailer replacement

Used on travel trailer to replace failed auto changeover regulator on dual tank setup. Tested at home, now in the middle of 5 day excursion. Working good as far as I can tell. With this regulator it hasn’t been as hard to get the gas refrigerator to fire up initially as it was with the old regulator.


Good quality part for lower price.
