This small-bore piston fits inside a flow check or piston-type metering device and controls the refrigerant flow rate entering the evaporator coil. It is a direct OEM-style replacement component sourced through Danfoss LLC and is installed by licensed HVAC technicians as part of a refrigerant system service or refrigerant conversion. The compact design measures 0.5 inches in height and 15\/32 inches in width, and it ships in a pack quantity of two units.\u003c\/p\u003e\u003cp\u003eThis piston is intended for HVAC systems using R-32 refrigerant where the existing flow check assembly requires a replacement metering orifice. Typical applications include residential split systems and packaged units that use a piston-type fixed metering device in place of a thermostatic expansion valve. The part is sold as a piston kit under the Goodman product line and is manufactured to OEM specifications through Danfoss LLC under vendor part number 119F7004.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.049-inch orifice diameter for precise refrigerant metering in R-32 systems\u003c\/li\u003e\n\u003cli\u003eOEM-specification replacement sourced through Danfoss LLC\u003c\/li\u003e\n\u003cli\u003eCompact form factor: 0.5 inches tall, 15\/32 inches wide\u003c\/li\u003e\n\u003cli\u003eLightweight construction at 0.017 pounds per unit\u003c\/li\u003e\n\u003cli\u003eSold in a pack quantity of two pistons\u003c\/li\u003e\n\u003cli\u003eManufactured in the United States\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement flow check piston for Goodman HVAC systems using R-32 refrigerant and piston-type fixed metering devices.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician certified to handle refrigerant under Section 608 of the Clean Air Act. Recover all system refrigerant and confirm system pressure is at zero before opening any refrigerant circuit components. Inspect the flow check housing for debris or damage before seating the new piston. Do not mix piston orifice sizes within the same metering assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrifice Size\u003c\/strong\u003e: 0.049 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefrigerant Type\u003c\/strong\u003e: R-32\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: 15\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Weight\u003c\/strong\u003e: 0.017 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity\u003c\/strong\u003e: 2\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 Part Number\u003c\/strong\u003e: 119F7004\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: b1789849\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GOODMAN","offers":[{"title":"Default Title","offer_id":51138247295282,"sku":"B1789849","price":26.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305526095.jpg?v=1778251572","url":"https:\/\/voomisupply.com\/products\/goodman-b1789849-flow-check-piston-0-049-inch-r-32","provider":"Voomi Supply","version":"1.0","type":"link"}
