• Industrial Grade Durability: Engineered for Carrier 50 series units to handle extreme pressure and temperature fluctuations.
• Streamlined Installation: Direct-fit replacement header assembly reduces the need for field modifications or piping adjustments.
• Balanced Pressure Drop: Maintains system-wide hydraulic balance to protect compressor longevity and efficiency.

Common Questions

Does this header assembly include the mounting hardware or gaskets?
The 50DK406356 includes the main manifold structure; however, secondary seals or specific mounting fasteners should be inspected and ordered separately if existing hardware shows signs of fatigue.

How do I verify if this header is compatible with my specific rooftop unit?
Confirm the model and series number on your data plate. This assembly is standard for specific Carrier commercial rooftop units; cross-referencing the internal parts list is recommended for exact fitment.

Can this header be used for both evaporator and condenser applications?
This specific part number is designed for the configuration specified in the 50DK series technical manual. Verify the circuit flow direction and port count before brazing to ensure proper heat exchange performance.
