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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1789882\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Refrigerant metering piston \/ flowrator kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (OEM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e GSC130483AE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Fixed-orifice refrigerant metering device\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment:\u003c\/strong\u003e Split-system air conditioner\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003ePiston bore size is everything — an incorrect generic orifice will over- or under-feed the coil, causing poor cooling, high head pressure, or compressor stress.
