Utica-Dunkirk 14615005 Pilot Tubing

For service technicians maintaining gas-fired systems, the Utica-Dunkirk 14615005 pilot tubing is a standard OEM replacement designed for reliable fuel delivery to the pilot burner assembly. This 1/8" x 24" aluminum pilot tubing features an annealed construction, allowing for precise field bending without kinking, which is essential when navigating tight boiler cabinets or burner compartments. With a total length of 24 inches and a standard 1/8-inch outer diameter, this HVAC pilot gas line ensures a consistent flow of natural gas or propane to the pilot orifice, supporting proper thermocouple heating and reliable main burner ignition. Using genuine Utica boiler replacement parts like the 14615005 prevents common pressure drop issues often associated with restricted or fouled lines. Replacing a corroded or obstructed gas pilot supply tube is a critical step in troubleshooting weak pilot flames or intermittent ignition cycles in residential heating units.

• OEM Compatibility: Specifically engineered for Utica and Dunkirk boiler systems to ensure a perfect fit with standard compression fittings.
• Durable Aluminum Construction: Offers high resistance to corrosion and thermal stress found within gas-fired appliances.
• Field-Flexible: The annealed aluminum allows for easy routing and shaping in the field while maintaining structural integrity.
• Optimized Flow: Smooth internal bore minimizes friction, helping maintain the correct gas-to-air ratio for a stable pilot flame.

• Can I cut this tubing to a shorter length? Yes, this 24-inch tube can be trimmed using a dedicated tube cutter. Ensure you ream the ends to remove burrs before installing compression sleeves and nuts.
• What causes a pilot tube to fail? Most failures occur due to carbon buildup (soot) clogging the line, vibration-induced stress cracks, or corrosion from moisture in the gas supply.
• Is this compatible with both Propane (LP) and Natural Gas? Yes, the 14615005 tubing is rated for both fuel types, provided the pilot burner orifice is correctly sized for the specific gas being used.
