Evaporator Core Orifice
NOTE: A new evaporator core orifice should be installed whenever a new A/C compressor is installed.
The evaporator core orifice is located in the condenser-to-evaporator line, and can be removed through an access fitting. The evaporator core orifice
provides a restriction to the flow of refrigerant from the high-pressure side of the refrigerant system and separates the low-pressure and high-pressure
sides of the refrigerant system.
