The kit includes a piston with a 0.080-inch orifice that controls refrigerant flow direction and rate through the system's metering device assembly. This type of fixed-orifice piston replaces a TXV or serves as the primary metering component in piston-style refrigerant circuits. HVAC technicians install this kit during system commissioning, refrigerant circuit repairs, or when converting a system to a different orifice size to match a new indoor or outdoor unit.\u003c\/p\u003e\u003cp\u003eThis flow check piston kit is suited for residential and light commercial split-system heat pumps and central air conditioners that use a piston-style metering device. The 0.080-inch orifice size is matched to specific system capacities and refrigerant types, making orifice selection critical to system efficiency and proper superheat. Technicians replacing a mismatched piston, repairing a failed check assembly, or performing a matched-system changeout will find this a direct-fit OEM-style replacement component.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.080-inch orifice diameter for fixed metering of refrigerant flow\u003c\/li\u003e\n\u003cli\u003eCompact form factor: 0.5 inches tall, approximately 0.469 inches wide\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.017 pounds for easy handling during installation\u003c\/li\u003e\n\u003cli\u003eOEM-style fit for piston-type refrigerant metering device assemblies\u003c\/li\u003e\n\u003cli\u003eManufactured in the United States\u003c\/li\u003e\n\u003cli\u003eSold individually; pack multiple quantity of 20 available for stocking orders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement piston for residential and light commercial split-system heat pump and air conditioning units that use a flow check piston metering assembly.

Recover all system refrigerant before disassembling the metering device assembly. Confirm the replacement orifice size is correct for the matched indoor and outdoor unit combination prior to reassembly. Follow the equipment manufacturer's service instructions and applicable mechanical codes when completing the repair.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrifice Size\u003c\/strong\u003e: 0.080 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Height\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Width\u003c\/strong\u003e: 0.469 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.017 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Class\u003c\/strong\u003e: Conversion Kits and Orifices\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Type\u003c\/strong\u003e: Accessory\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: United States\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVendor\u003c\/strong\u003e: Danfoss LLC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVendor Part Number\u003c\/strong\u003e: 119F7006\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GOODMAN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: b1789880\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GOODMAN","offers":[{"title":"Default Title","offer_id":51138403303730,"sku":"B1789880","price":28.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305526188.webp?v=1778255423","url":"https:\/\/voomisupply.com\/products\/goodman-b1789880-flow-check-piston-kit-0-080-inch-orifice","provider":"Voomi Supply","version":"1.0","type":"link"}
