Pilot Tube Assembly, Natural Gas by Rheem®.

Rheem AP14317U-1 OEM Pilot Tube Assembly – Natural Gas Ignition Component

The Rheem AP14317U-1 is an original equipment manufacturer (OEM) pilot tube assembly designed for use with natural gas-fired water heaters. This component facilitates gas flow between the gas valve and the pilot burner, maintaining stable delivery to ensure consistent pilot ignition in compatible systems.

Functional Overview

This pilot tube is factory-formed and sized to meet exact tolerances for use in specified Rheem atmospheric vent models. It includes compression fittings for direct installation into the burner assembly and control valve. The design supports efficient gas delivery under standard operating pressures and is compatible with standing pilot ignition systems where thermocouple-based flame validation is used.

Technical Specifications

• Part Number: AP14317U-1
• Type: Natural Gas Pilot Tube Assembly
• Material: Precision-formed metal tubing (copper or equivalent alloy)
• Connection: Compression fittings at both ends (gas control and pilot burner)
• Application: OEM replacement for select Rheem water heater models
• Ignition System: Standing pilot (manual light or piezo-assisted)

Installation Requirements

Installation should be performed with the system powered down and fully depressurized. The AP14317U-1 is a form-specific replacement part; it must not be altered, extended, or reshaped, as this can affect performance and safety. Proper sealing, torque, and gas leak testing are required after installation. All work should comply with current local and national gas code regulations.

Professional Use Cases

Intended for field replacement of worn, kinked, or obstructed pilot tubing assemblies during water heater maintenance or repair. The AP14317U-1 supports system restoration where inconsistent pilot flame, delayed burner ignition, or thermocouple signal loss may be occurring due to pilot tube flow restriction or misalignment. It is commonly stocked by service contractors for responsive field diagnostics and system repairs.
