The piston meters refrigerant flow into the coil to maintain proper system charge and pressures, which is essential for correct cooling capacity and efficiency. The factory-sized orifice in this kit is matched to the system, so installing the correct OEM piston is critical to performance.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1789857\u003c\/li\u003e\n\u003cli\u003ePart Type: Piston \/ Flowrator (refrigerant metering device)\u003c\/li\u003e\n\u003cli\u003eCompatible Model: SSX140241AA\u003c\/li\u003e\n\u003cli\u003eEquipment: Goodman Air Conditioner Condenser\u003c\/li\u003e\n\u003cli\u003eFunction: Meters refrigerant flow to the coil\u003c\/li\u003e\n\u003cli\u003eIncludes: Piston and seal hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis authentic Goodman OEM piston is bored to the exact factory orifice size for the SSX140241AA. Generic pistons may carry the right physical body but an incorrect bore, which leads to improper charge, poor cooling, and reduced efficiency. For correct system performance, always use the OEM-specified piston.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eAdvanced — Professional Recommended.\u003c\/strong\u003e Replacing the piston requires opening the sealed refrigerant circuit, so recovery, evacuation, and recharging by an EPA 608–certified technician are required. This is not a DIY repair. Typical professional time: 1–2 hours. Improper handling can damage the system and violates refrigerant-handling regulations.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057204281715,"sku":"GOODMAN-854","price":10.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-piston-flowrator-kit-for-ssx140241aa-b1789857-1","provider":"National HVAC Parts","version":"1.0","type":"link"}
