Marshall Excelsior Flow Longer Plus LP Adapter Fitting MER473 06-0253

The flow-longer propane kits are designed to connect small, portable appliances, normally fueled by disposable LP-Gas cylinders, to the existing LP-Gas fuel supply of a recreational vehicle, cottage, backyard patio, etc. without interrupting the supply of regulated fuel to the system. Flow-longer eliminates the need to purchase an extra LP-Gas cylinder or several small, disposable type cylinders.
