The Southbend SOU1177448 Range Rear Pilot Tube Assembly is a gas flow component designed to supply fuel to the rear pilot burner in compatible commercial ranges. It works by channeling a controlled stream of gas through the tube to the pilot orifice, where it is ignited to maintain a steady flame for burner activation. This ensures dependable lighting of the main burners when required. Its durable construction supports long-term use in high-temperature environments, helping improve ignition consistency, reduce operational interruptions, and maintain safe, efficient performance in commercial kitchen equipment.
