Carrier 50HJ402677 Header Assembly

The Carrier 50HJ402677 Header Assembly is a high-precision OEM replacement part designed for specific Carrier, Bryant, and Payne package units. As a critical component within the refrigerant distribution system, this header assembly manages flow to the evaporator coil, ensuring balanced heat transfer and preventing evaporator circuit restrictions. Built to RCD Parts exacting standards, this factory authorized part ensures a drop-in replacement that maintains the original equipment’s SEER ratings and internal pressure balances. For field technicians, utilizing a genuine 50HJ402677 is essential when diagnosing low superheat or uneven frosting across coil circuits, which often indicates a failed or restricted Accurator metering device within the manifold. This assembly features a compact design with a length of 4.7 inches and a width of 22 inches, providing the reliable HVAC manifold performance required in demanding commercial environments where system downtime must be minimized.

• Precise Refrigerant Distribution: Engineered to eliminate coil circuiting imbalances, ensuring the evaporator coil operates at peak thermal efficiency.
• OEM Compatibility: Guaranteed fit for Carrier 50HJ series units, eliminating the need for field modifications or surgical tube repairs.
• Durable Construction: Manufactured to resist vibration and thermal stress within high-pressure R-410A systems.
• Optimized System Performance: Restores factory-spec refrigerant flow management to help resolve high-discharge pressure or low-suction pressure issues caused by old header restrictions.

• Is this assembly compatible with non-Carrier units? This is a Factory Authorized Part specifically engineered for Carrier, Bryant, and Payne equipment. Always verify your model and serial number before installation.
• Does this include the Accurator metering pistons? Yes, as a complete header assembly, it is designed to replace the specific liquid line distribution manifold and its integrated metering components.
• What are the symptoms of a failing header? Technicians often identify a failing header through significant temperature pits between different circuits on the evaporator coil or localized frosting at the distributor tubes.
