Description

New RV propane regulator MEGR-253P is a high-quality Excela-Flo two-stage automatic changeover regulator designed for reliable RV propane systems that require continuous gas supply from dual cylinders.

Manufactured by Marshall Excelsior Company, this regulator automatically redirects LP gas vapor flow from the empty service cylinder to the reserve cylinder—without interrupting appliance operation. A clear, easy-to-read indicator changes from green to red when the service cylinder needs to be refilled.

Built with a die-cast zinc body and powder-coated finish, the MEGR-253P is designed for long service life in demanding RV environments. The internal spring-loaded diaphragm relief system provides stable outlet pressure and added safety.

This model is RV approved and meets UL, RVIA, and NFPA requirements, making it an excellent replacement or upgrade for many dual-tank RV propane systems.
