Carrier 50DK406006 Header Assembly

The Carrier 50DK406006 Header Assembly is a critical OEM replacement part designed for precision refrigerant distribution within residential and commercial evaporator coils. Built to strictly handle high-pressure regional demands, this coil header assembly ensures balanced flow across the circuit, preventing uneven heat transfer or liquid slugging. As a genuine Carrier HVAC part, the 50DK406006 maintains the factory specifications required for high-efficiency operation in PA1REA, PA1RJA, and PY1REA series units. Its durable construction is engineered for long-term reliability in varying thermal conditions, making it the standard choice for contractors performing a professional coil manifold repair. This specific freon distribution header is manufactured in the United States and serves as a direct drop-in for units requiring exact port alignment and tubing diameter to maintain system pressure integrity and design subcooling levels.

• Direct OEM Compatibility: Engineered specifically for Carrier, Bryant, and Payne units to ensure perfect fitment and eliminate field modification.
• Optimized Refrigerant Flow: Balanced headers prevent performance degradation by ensuring equal BTU loading across all coil circuits.
• Industrial Build Quality: High-grade materials designed to withstand the stresses of high-pressure 410A systems.
• System Efficiency Restoration: Replacing a fouled or leaking header restores the original factory airflow and heat exchange ratings.

What models are compatible with the 50DK406006?
This assembly is utilized specifically in 5-ton PA1REA, PA1RJA, PA1RPA, PY1REA, and PY1RJA series units. Always verify your specific model and serial suffix before installation.

Does this header include the distributor tubes?
The 50DK406006 serves as the primary distribution manifold. While most assemblies come with pre-staged ports, verify if your specific application requires additional capillary tubes or thermal expansion valve integration.

Can this be used for R-22 to 410A conversions?
This header is designed for modern high-pressure refrigerants. If retrofitting, ensure all downstream components, including the coil and metering device, are rated for the increased pressure and oil compatibility.
