Marshall Excelsior Flow-Longer Plus Propane Adapter Kit

The Marshall Excelsior Flow-Longer Plus kit connects small portable appliances – normally powered by disposable LP cylinders – to your RV's existing propane supply, without interrupting regulated fuel to the rest of the system. It's an easy way to power patio or camp appliances from your main tank.

Flow-Longer Plus eliminates the need to buy extra or disposable cylinders, keeping your appliances running longer between refills.
