Marshall Excelsior Stay-Longer Plus Propane Adapter Kit

The Marshall Excelsior Stay-Longer Plus kit lets you connect additional propane appliances to your RV's existing LP-gas supply, so you can keep cooking, grilling, or heating without swapping small disposable cylinders. It uses a brass tee connection with excess-flow protection for safe, uninterrupted flow.

The kit includes a brass tee connection and hoses to link your appliance into the regulated fuel system, extending your run time between refills.
