Marshall Excelsior MER471 Flow-Longer-Plus Propane Adapter Kit with Brass Elbow

The Marshall Excelsior Flow-Longer-Plus Propane Adapter Kit allows you to connect small, portable LP-Gas appliances—normally powered by disposable propane cylinders—directly to your RV, camper, cottage, or backyard patio's existing LP-Gas supply. This convenient kit eliminates the need to purchase extra propane tanks or multiple disposable cylinders while maintaining uninterrupted fuel supply to your system.

Kit Includes:

• Brass elbow connection (ME423) for secure, durable installation
• 0.9 GPM excess flow valve with male hard nose POL x 1-5/16 inch male ACME/female POL with quick closing poppet x 1 inch-20 female threading
• 12-foot propane hose (MER421-144) with 1 inch-20 male x 1 inch-20 female connections
• Installation instructions and reusable storage box

Installation Note: The tee fitting must be installed between the vapor withdrawal valve on your LP-Gas container and the pressure regulator, placing it in the high-pressure portion of the system. Gas connections should not be moved or rotated after installation to avoid flexing, twisting, or vibration.

The excess flow valve provides an added safety feature by restricting flow in case of a downstream break or leak. Ideal for RV owners, campers, and outdoor enthusiasts who want the flexibility to use portable propane appliances without the hassle of managing separate fuel sources.
