Nordyne 664067R Orifice
The Nordyne 664067R Orifice is a precision-engineered .067 restrictor orifice designed to maintain critical refrigerant flow rates in specific HVAC systems. As the direct replacement for 664067, this #67 orifice is essential for contractors performing maintenance or repairs on Nordyne air conditioner and Miller furnace matching coils. Proper sizing of the metering device is vital for achieving the correct superheat and ensuring the evaporator coil operates at peak efficiency. This fixed-bore component simplifies system calibration by providing a consistent R-410A flow rate or R-22 equivalent, depending on the system design pressure drop requirements. Using an authentic HVAC expansion orifice prevents liquid slugging and evaporator freeze-ups, protecting the compressor. When replacing a Nordyne 664067, ensuring the seat is clean and the restrictor plate is seated correctly is standard practice for a professional HVAC orifice installation.
- Exact Metering: Delivers a consistent .067 bore size for precise refrigerant expansion.
- Direct OEM Fit: Engineered specifically as the 664067R replacement to ensure housing compatibility.
- Durable Construction: High-grade brass machining resists erosion and prevents metering device bypass.
- System Optimization: Critical for matching indoor coil capacity with outdoor condensing units.
Common Questions
Is the 664067R Orifice compatible with R-410A systems?
Yes, this metering orifice is frequently used in high-pressure R-410A applications, provided the system service manual specifies a .067 opening for the specific tonnage and line set length.
What is the difference between 664067 and 664067R?
The "R" designation typically indicates a revised or updated manufacturer part number. The 664067R functions as a direct fit and 1:1 performance replacement for the legacy 664067 part.
How do I ensure this orifice is the correct size for my unit?
Refer to the rating plate on the outdoor condenser. Most Nordyne-manufactured units list the required piston or orifice size on the technical specification label to ensure a proper thermal match.
