The flowrator (piston-style metering device) tube delivers liquid refrigerant into the coil at the correct point and orientation so the piston meters charge evenly across the circuits. A kinked, corroded, or incorrect inlet tube causes poor refrigerant distribution, low capacity, coil icing, and reduced efficiency.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e B1796630\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Flowrator \/ metering inlet tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Refrigerant inlet to evaporator coil\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 WAHMS4860P4ABA air handler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment:\u003c\/strong\u003e Air Handler\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine Goodman OEM\u003c\/strong\u003e tube is bent to the exact length and geometry required to mate with the coil distributor and flowrator body.
