Extend a Stay RV Propane Kit - 4-Port Brass Tee with 5ft and 12ft

In this review the Extend a Stay RV Propane Kit is evaluated for RV owners who want a simple way to add an auxiliary cylinder or an extra appliance to their onboard propane system. The single biggest reason to consider this kit is its combination of a 4-port solid brass tee and stainless braided hoses that let an RVer safely split and extend propane connections without replacing the main regulator. The review finds it most useful for occasional auxiliary tanks and added outdoor appliances, while noting some customers report leakage that should be checked during installation.

Key Features

• Upgraded Design: The brass tee includes overcurrent protection to reduce the risk of gas line damage during connection events.
• Auxiliary Tank Hose: The included 5ft stainless braided hose with soft-nose male POL x 1/4' inverted male flare is meant to link an auxiliary LP cylinder to the RV system.
• Appliance Extension Hose: The 12ft stainless braided hose with 1'-20 male swivel throwaway to 1'-20 female swivel thread enables locating an extra appliance farther from the tank.
• Durable Materials: All adapters are 100% solid brass and the hoses are stainless braided for weather resistance and corrosion protection.
• Complete Kit: Package includes the 4-port tee, both hoses, sealing tape and Velcro straps, making it ready for installation.

Who It's For

The kit is aimed at motorhome and RV owners who want a flexible way to connect an auxiliary propane cylinder or add an outdoor appliance without modifying the primary tank or regulator. It suits DIY-minded users comfortable tightening fittings with a wrench and checking for leaks after installation.

Those who need certified leak-proof, commercial-grade plumbing for permanent installations or who are uncomfortable working with propane fittings should consult a professional or choose factory-installed solutions. Several buyers reported leakage issues, so users expecting a plug-and-play, maintenance-free solution may want to be cautious.
