Marshall Excelsior Flow-Longer Propane Adapter Kit

The Marshall Excelsior Flow-Longer kit lets you run small portable appliances – normally fed by disposable LP cylinders – directly from your RV's existing propane supply, without interrupting regulated fuel to the rest of the system. It's a convenient way to power a patio appliance or camp accessory.

The kit includes a brass tee connection with excess-flow protection and a 12-foot hose, so you can keep appliances running without buying extra or disposable cylinders.
