Is It Possible To Connect Two Propane Regulators In Line  

Question:

I have a Coleman 2-burner camp cook stove that I have used disposable bottles with in the past. I just bought a nuCamp TAB 400 trailer with a quick disconnect gas line outlet at the rear of the trailer. The Coleman stove has its own preset regulator. Can I use this part to connect the female on the trailer to the stove? Other vendors state that you can only have one regulator in the path and that you may need to remove the regulator on the 20-lb propane tank on the trailer. This sounds wrong to me. Including pictures.

Unfortunately this will not work. The regulator on your trailer reduces propane under high pressure to pressure that will support a column of water approximately 11-inches high. The proprietary regulators used on Coleman and other similar camp stoves will support a column of water somewhat higher, not lower. If you “adapt” a Coleman type stove to run on what is considered a low pressure system (already regulated down to at 11 inches, you will get hardly any flame and it would only serve as a “warmer.” And placing two regulators in series will reduce gas pressure to almost nothing.

The Coleman must be used with the pressures that come directly out of a propane tank, either refillable or the small disposable ones. If you want to eliminate the small one pound disposable bottles, you need a tap before the regulator like the MB Sturgis Sturgi-Stay T-Fitting for Type 1 Valve # 103613-MBS. which would allow you to not have to remove your regulator at the tank. Or you can purchase a stove like the Camp Chef Ranger II, which can be used on a low pressure system.
