Goodman B1789857 Piston / Restrictor Kit

This genuine OEM Goodman B1789857 piston kit is the factory refrigerant metering device (fixed-orifice restrictor) used with SSX140241AC 14 SEER, 2-ton air conditioning systems. The piston meters refrigerant flow into the evaporator coil at the precise orifice size the system is engineered for, which is essential for correct superheat/subcooling, rated capacity, and efficiency. Installing the correct OEM piston is critical whenever a coil is replaced or a system is matched, because an incorrect orifice size directly degrades cooling performance.

Specifications

OEM Part Number: B1789857
Part Type: Piston / fixed-orifice metering device (restrictor kit)
Fits Model: SSX140241AC (Goodman 14 SEER, 24,000 BTU AC)
Function: Meters refrigerant flow to the evaporator coil
Application: Coil replacement and system matching

OEM vs. Generic

Piston orifice sizing is calibrated to the specific equipment match. The OEM B1789857 guarantees the exact bore the system was designed around. Generic or mis-sized pistons can cause flooding, starving, poor efficiency, or compressor stress. For a metering component, using the factory-specified part is strongly recommended.

Installation Difficulty

Advanced — professional recommended. Replacing a piston requires opening the sealed refrigerant circuit: recover refrigerant, replace the piston in the line set/coil fitting, evacuate, and recharge. This is EPA-regulated work and should be performed by a licensed HVAC technician.
