Lochinvar & A.O. Smith 100109875 Pilot Tube
The Lochinvar & A.O. Smith 100109875 Pilot Tube is a critical 1/4" OD aluminum supply line designed for precise gas delivery to the pilot burner assembly. Measuring 24 inches in length, this HVAC replacement pilot tubing is engineered to withstand the thermal stresses of continuous operation in residential and commercial gas water heaters. As a veteran-grade water heater repair part, it serves as a direct replacement for damaged or kinked lines, ensuring consistent pilot flame stability and reliable ignition cycles. Compatible with a broad range of Lochinvar and A.O. Smith models, this 100109875 kit often replaces legacy part numbers such as 23330 and 9004473115. The 1/4 inch pilot line comes equipped with the necessary compression fittings to provide a leak-proof seal at frequencies required for high-efficiency thermal expansion. For contractors performing a gas control valve replacement, utilizing this OEM-spec 24-inch tube prevents common field issues where shorter stock lines fail to reach the manifold assembly. Always verify the orifice and compression nut torque to maintain optimal gas flow and prevent nuisance lockouts.
Key Benefits:
- High-Grade Aluminum Construction: Provides superior corrosion resistance and malleability for easy routing around the burner tray.
- Universal 24" Length: Offers sufficient slack for manifold-to-pilot connections, making it ideal for large-tank commercial units.
- Precision Compression Fittings: Ensures a gas-tight seal, minimizing the risk of pilot outages or hazardous gas leaks.
- OEM Compatibility: Cross-references with A.O. Smith 100109875 and Lochinvar systems to maintain factory performance standards.
Common Questions:
- Can this tube be cut to fit shorter applications? Yes, if your unit requires a shorter run, this aluminum tubing can be trimmed with a standard tubing cutter; however, ensure the ends are properly deburred before seating the 1/4" compression fitting.
- Will this work with both LP and Natural Gas? This pilot tube is a conduit and is compatible with both gas types, provided it is paired with the correct pilot burner orifice for your fuel source.
- What causes a pilot tube to fail? Most failures result from physical damage during service, carbon buildup at the tip, or heavy oxidation from moisture in the combustion air.
