Marshall Excelsior MER471 Flow-Longer Plus Kit

The Flow-Longer Propane Kits are designed to connect small, portable appliances, normally fueled by disposable L.P. gas cylinders, to the existing L.P. 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 L.P. gas cylinder or several small disposable type cylinders.
