Description
The Nordyne 664053R .053″ Restrictor Orifice 53 is used in systems to regulate refrigerant flow through a fixed, calibrated opening. It is applied in compatible furnace and air conditioning assemblies. This part operates by controlling the rate at which refrigerant passes into the evaporator section, maintaining balanced pressure and stable cooling output within HVAC systems. These components, such as residential split air conditioners and furnace-linked cooling setups use this orifice within the refrigerant circuit. It is positioned inside the refrigerant line assembly to support steady system circulation and consistent thermal exchange during heating and cooling cycles.
