Nordyne 664087R Restrictor Orifice
The Nordyne 664087R Restrictor Orifice is a critical fixed-bore metering device engineered for precise refrigerant expansion in HVAC evaporator coils. With an exact inner diameter of .087 inches (Size #87), this OEM Nordyne part is designed to replace worn or fouled orifices that cause irregular superheat or subcooling readings. Proper sizing of the flow restrictor orifice is essential for maintaining the pressure drop required for efficient phase change, preventing liquid slugging of the compressor while ensuring the coil is saturated for maximum heat transfer.
As an OEM HVAC replacement part, the 664087R ensures compatibility with Nordyne, Nortek, Intertherm, and Miller residential systems. Field technicians often encounter restricted orifices due to debris from a failing filter drier or wax buildup; replacing the piston orifice during a system flush restores factory-spec refrigerant flow control. This component is constructed from high-grade, corrosion-resistant materials to withstand the high-velocity turbulent flow of modern refrigerants and maintain its fixed orifice size over years of service.
Key Benefits:
- Precision Metering: Ensures a consistent refrigerant expansion rate for stable evaporator pressure and optimized cooling capacity.
- OEM Engineering: Guaranteed fit for Nordyne-manufactured split systems and package units, eliminating the risks associated with generic refrigerant orifices.
- Enhanced Efficiency: Restores manufacturer-intended system pressure regulation, helping to lower energy consumption and prevent compressor strain.
- Durable Construction: Built to resist erosion and clogging, maintaining the integrity of the .087 orifice diameter.
Common Questions:
How do I know if the restrictor orifice is clogged?
A restricted Nordyne orifice typically presents with high subcooling at the liquid line and high superheat at the suction line. You may also see frost buildup at the evaporator coil inlet immediately following the metering device.
Can I use an .087 orifice for any Nordyne unit?
No. The orifice size #87 is matched to specific BTU capacities and SEER ratings. Always verify the required piston size on the unit's data plate or nameplate before installation to avoid flooding the coil or starving the evaporator.
Is this part compatible with R-410A systems?
The Nordyne 664087R is designed to handle the pressures of professional HVAC systems, but the specific piston orifice size must be cross-referenced with your specific refrigerant flow requirements and equipment matchups.
