Goodman B1789882 Refrigerant Piston (Flowrator) Kit

The Goodman B1789882 is a genuine OEM refrigerant metering piston — often called a flowrator or orifice — engineered for the GSC130483AE condensing unit and matched Goodman air conditioner systems. The piston meters liquid refrigerant into the evaporator coil at a precise rate, which is critical for correct superheat, capacity, and energy efficiency. Using the factory-specified orifice size ensures the system charges and performs exactly as engineered.

Specifications

Part Number: B1789882
Type: Refrigerant metering piston / flowrator kit
Brand: Goodman (OEM)
Fits Model: GSC130483AE
Function: Fixed-orifice refrigerant metering device
Equipment: Split-system air conditioner

OEM vs. Generic

Piston bore size is everything — an incorrect generic orifice will over- or under-feed the coil, causing poor cooling, high head pressure, or compressor stress. The genuine Goodman B1789882 carries the exact factory bore for this system, so the charge and performance land where the manufacturer intended.

Installation Difficulty

Advanced — Requires opening the sealed refrigerant circuit. Recovery, evacuation, and recharging by an EPA 608-certified technician are required. Not a DIY job for the typical homeowner.
