The piston is the fixed-orifice metering device that sets refrigerant flow into the coil. Matching the correct orifice size to the system is essential for proper superheat, capacity, and efficiency — a wrong or worn piston causes poor cooling, high energy use, or coil frosting.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Fixed-orifice piston \/ flowrator metering device\u003c\/li\u003e\n\u003cli\u003eFunction: Refrigerant metering into the coil\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana ANZ130241AA heat pump\u003c\/li\u003e\n\u003cli\u003eEquipment: Heat pump condensing unit\u003c\/li\u003e\n\u003cli\u003eKit: Piston with seals\/retainer as applicable\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine OEM piston is bored to the exact orifice diameter this system was engineered for.
