Carrier 50DK407029 Burner Tube

The Carrier 50DK407029 Burner Tube is a factory-engineered OEM replacement part designed for high-efficiency gas-fired systems. This inner burner tube is essential for maintaining a precise gas-air mixture, ensuring stable in-shot burner combustion and maximum heat transfer. Constructed from high-grade, heat-resistant aluminized steel, it is built to withstand the extreme thermal cycling common in commercial and residential rooftop units and furnaces. With a length of 6 3/8" and an outer diameter of 1 7/16", this component provides a secure fit in the burner tray, preventing flame rollout and ensuring consistent HVAC burner assembly performance. Replacing a rusted or pitted 50DK407029 restores proper ignition sequences and reduces emissions caused by incomplete combustion. This component is compatible with various Carrier, Bryant, and Payne models, including the 48GCTM, 574DPW, and 48FCRM series. For professional contractors, utilizing this genuine Carrier burner tube ensures that the system maintains its original engineering specifications and combustion efficiency.

• Durable Thermal Resistance: Fabricated from materials designed to resist oxidation and scaling under high-temperature industrial environments.
• Precision Flame Control: The in-shot design optimizes the gas-air mixing process to create a stable, efficient flame.
• Exact Technical Specs: Features a 6 3/8" length and 1 7/16" O.D. for a seamless drop-in installation without field modification.

Is the 50DK407029 compatible with multiple furnace brands?
Yes, as a genuine Carrier part, it is the correct specification for many Carrier-made units labeled under the Bryant and Payne brands. Always verify the model and serial number before installation.

What are the signs that an inner burner tube needs replacement?
Technicians should look for visible cracks, heavy corrosion, or an uneven flame pattern (lazy flame), which indicates the tube is no longer providing proper secondary air-fuel mixing.

Does this burner tube include the orifice?
This is the inner burner tube assembly only. The gas orifice is a separate component and should be inspected during the burner replacement process.
