The flowrator (piston-style metering device) seats inside this inlet tube to control the flow of liquid refrigerant into the evaporator coil, maintaining correct superheat and cooling capacity. A damaged, kinked, or mismatched tube can cause poor cooling, frost on the coil, or refrigerant flooding, so an exact-fit OEM tube is essential for proper system charge and performance.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: B1796630\u003c\/li\u003e\n\u003cli\u003eType: Flowrator \/ metering inlet tube\u003c\/li\u003e\n\u003cli\u003eFits Model: WAHMS3743P4ABA air handler\u003c\/li\u003e\n\u003cli\u003eFunction: Houses piston metering device feeding the evaporator coil\u003c\/li\u003e\n\u003cli\u003eMaterial: Copper tubing assembly\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis genuine Goodman inlet tube matches the exact bore, length, and fitting size required by the WAHMS3743P4ABA coil circuit.
