The Carrier EA52PH057 is a genuine OEM replacement piston designed to deliver accurate refrigerant metering in compatible Carrier HVAC systems. Pistons serve as fixed-orifice metering devices that regulate the flow of refrigerant into the evaporator coil, playing a critical role in maintaining proper system efficiency, capacity, and pressure balance.
Why Use a Genuine OEM Piston?
