Product Code: VTS-372A

Our Price:



This two-stage automatic changeover LP gas regulator is one of the most important pieces of equipment on any travel trailer.

With this high quality Italian-made Cavagna model, you get continuous gas supply by automatically changing to a reserve cylinder when the service cylinder is empty. The highly visible red/green indicator on the regulator changes color to signal when the service cylinder needs to be refilled.

The bracket is an improvement over other brands because it is simply slipped over the threaded rod on your tank rack. The plastic vent cover is included and screwed to the back so it doesn't come off or get in the way.
