Description
The Nordyne 664041R Restrictor Orifice 41 is a fixed metering component used to regulate refrigerant flow within a .041″ opening in systems, and it is fitted into distributor assemblies in similar to air conditioning or heat pump units to control liquid refrigerant delivery to the evaporator coil. With fixed metering equipment rely on this orifice to maintain stable pressure balance and consistent coil feeding within HVAC systems. It works by limiting flow through a calibrated bore, supporting steady heat exchange and proper temperature sensing response. In compatible systems, it is placed inside the liquid line metering section to maintain controlled operation across cooling cycles.
