Description
The A.O. Smith 9004473115 Pilot Tube Kit 1/4″ x 24″ LG is a replacement tubing assembly used in gas-fired water heating and related combustion systems to carry pilot gas from the control valve to the pilot burner. It consists of a 24-inch aluminum tube with 1/4-inch diameter designed to maintain a stable, low-flow gas supply for ignition systems. In HVAC systems applications, it is commonly installed in commercial water heaters, and boiler units where an accurate pilot flame is required for the burner ignition. Within the appliance, it works as a conduit in the ignition train, ensuring consistent pilot delivery to support safe, and repeatable system start-up operations.
