Why Choose an OEM TXV?
Using a genuine Nordyne OEM thermostatic expansion valve ensures proper fit, function, and system compatibility. Aftermarket valves may not deliver the precise flow characteristics required by the EQ Series equipment, potentially leading to reduced efficiency, comfort complaints, or premature compressor failure. The 664349R is the correct, manufacturer-specified component for this application.
