Nordyne 664065R Orifice
The Nordyne 664065R Orifice is a precision-engineered .065 restrictor orifice designed for critical refrigerant flow regulation in high-efficiency refrigeration and air conditioning systems. As a veteran-grade OEM HVAC replacement part, this #65 flow restrictor ensures accurate pressure drops across the evaporator coil, optimizing heat transfer and preventing compressor slugging. Constructed from high-durability brass, the Nordyne 664065R is a direct-fit component for specific Nordyne, Miller, and Intertherm furnace and coil assemblies, including the 6640 and 6641 series. For field technicians, maintaining the exact orifice size designated by the manufacturer is non-negotiable for system charge balancing and thermal expansion valve (TXV) bypass applications. Utilizing this refrigerant metering device helps eliminate sub-cooling issues and ensures the system operates within peak HVACR technical specifications. Whether you are performing a seasonal tune-up or a full system overhaul, verify the part compatibility with your specific model number to ensure seamless integration and long-term mechanical reliability under varied load conditions.
Key Benefits:- Precision Metering: Delivers a consistent .065-inch aperture for exact refrigerant distribution and system efficiency.
- OEM Compatibility: Engineered as a genuine Nordyne replacement part for guaranteed fitment in compatible air handlers and furnaces.
- Durable Construction: Heavy-duty brass build resists corrosion and thermal fatigue in high-pressure environments.
- Performance Restoration: Corrects improper refrigerant flow issues, helping to stabilize suction pressure and evaporator temperatures.
Is the Nordyne 664065R compatible with R-410A systems?
Yes, provided the system’s BTU rating and manufacturer’s charging chart specify a .065 restrictor size. Always cross-reference the model plate of the evaporator coil.
What symptoms indicate a faulty or clogged orifice?
Common indicators include uneven frost patterns on the evaporator coil, high superheat readings, and diminished cooling capacity despite a correct refrigerant charge.
Can this orifice be used for both heating and cooling cycles?
This restrictor orifice is specifically designed for the liquid line or distributor assembly to meter flow during the cooling cycle in targeted furnace and AC configurations.
