About the Suburban LP-R528B Automatic Changeover Regulator

The Suburban LP-R528B is an automatic changeover LP gas regulator designed for RV propane systems with two propane cylinders. It allows one cylinder to serve as the primary supply while the second cylinder remains in reserve, helping maintain gas flow when the selected cylinder runs empty.

This regulator is commonly used in RV propane compartments where two cylinders feed appliances such as furnaces, water heaters, refrigerators, ovens, cooktops, and other LP gas equipment. The built-in changeover function helps reduce interruptions by switching to the reserve cylinder when properly installed and selected.
