Propane Adapter for 1-lb Coleman 9922 Stove/Grill Connection to Propane Tank  

Jon, Thanks for the reply. The MB Sturgis Adapter Hose kinda solves my problem but allow me to explain. I set out to do something that seemed easy, connect a portable propane grill to the propane tank/external connection on my RV but it turned out not to be so easy. Here’’s the long version of what I learned in the hope it is helpful to others. -So I learned propane systems have a high pressure side and low pressure side. The typical 20 lb tank, the white ones you get at Home Depot or Lowe’s are high pressure ~100PSI, as is the tank on the RV. The small disposable 1lb green bottles that many portable stoves/grills use are also high pressure. The appliance, stove, grill, lantern, etc uses low pressure, ~ .5 PSI. There are pressure regulators on the top of the 20 lb white tanks and the RV tank that reduce the pressure to a level appropriate for the appliances. The 1 lb green bottles typically screw into a conical aluminum fitting that connects to the stove/grill, it is also a pressure regulator. -I learned if you have plumbing such that 2 pressure regulators are on the line…one at the RV tank and one at the portable stove/grill, you get no pressure and cannot run the appliance. -After bypassing the stove fitting and connecting directly to the RV tank I found there was only enough pressure for my Coleman Stove/Grill to barely light up and function. Further research revealed that my particular Coleman Portable stove/grill ( and others I suspect) which run off the 1lb green bottles actually regulated pressure down to 10 or 15 PSI. That is the pressure this particular Stove/Grill was designed to work off of. I understand Stove manufactures do this to get more BTU’s and better performance in windy conditions. -In the end after much trial and error, I learned you need to search out a “low pressure stove/grill” to work off the RV tank. It’s not hard, there are lots of them out there at various retailers. Once you have a “low pressure stove/grill the MB Sturgis Propane Adapter Hose could help you plumb this solution. -Thank you for your time and patience. I hope this lengthy explanation helps another RV owner down the road.
