Each set within the 12-pack contains both PTFE O-rings and neoprene O-rings

Leak Prevention: Vital for maintaining system charge and preventing HVAC refrigerant leaks at the service port

5 microfarad capacitor provides the necessary phase shift to keep condenser fan motors and small compressors running efficiently under variable loads

This part is cross-compatible with several valve variants including the LF70A

Nordyne 664063R Restrictor Each set within the 12-packThe Nordyne 664063R is a precision engineered . 063 Restrictor Orifice #63 designed for precise refrigerant metering in specialized HVAC systems. As the direct replacement for Nordyne 664063, this component ensures consistent system pressure and optimal evaporator performance. This fixed bore ac restrictor orifice is critical for maintaining the correct refrigerant flow rate, preventing liquid slugging and ensuring the compressor operates within
