Nordyne 664062R Orifice
For service technicians working on mobile home or residential split systems, the Nordyne 664062R Orifice is the standard .062 Restrictor Orifice #62 designed for high-precision refrigerant metering. Built for compatibility with brands under the Nortek Global HVAC umbrella—including Intertherm, Miller, and Maytag—this fixed-bore metering device is critical for maintaining correct refrigerant flow control in evaporator coils. When replacing a clogged or improperly sized piston, using an OEM HVAC part like the 664062R ensures the system maintains the target superheat and subcooling levels required for efficient heat transfer.
This HVAC restrictor orifice is engineered from durable brass to withstand the high-pressure environment of R-410A or R-22 systems. The .062 orifice size is specifically calibrated to prevent liquid slugging and evaporator flooding, which can occur with oversized pistons. For contractors performing a coil swap or a refrigerant metering device replacement, verifying the #62 stamping is essential to match the manufacturer's liquid line specifications. Relying on genuine Nordyne replacement parts ensures consistent performance and minimizes the risk of early compressor failure caused by improper metering.
Key Benefits:
- Ensures precise refrigerant flow control for optimal evaporator coil performance.
- Direct OEM replacement part for Nordyne, Intertherm, Miller, and Broan equipment.
- Precision-machined .062 restrictor orifice for consistent pressure drop across the liquid line.
- Engineered to help maintain specific superheat and subcooling parameters during service.
- Simplifies HVAC repair by providing an exact match for factory-installed metering pistons.
Common Questions:
- How do I know if the .062 orifice is the correct size for my AC unit? Consult the manufacturer’s technical data sheet for your specific condenser and evaporator matchup consistently; the #62 orifice is often specified for 1.5 to 2-ton nominal capacities depending on the SEER rating.
- Can I use this orifice in an R-410A system? Yes, the Nordyne 664062R is compatible with modern refrigerants, provided the system’s flow requirements call for a .062 bore size.
- What happens if I install the wrong size restrictor orifice? An undersized orifice will starve the evaporator (high superheat), while an oversized orifice can flood the compressor with liquid refrigerant, leading to catastrophic failure.
