It features an internal flare on one end and an external flare on the other, allowing a 1\/4 inch connection to mate with a 3\/8 inch connection without additional adapters. Weighing 0.078 pounds, this compact brass fitting is a standard-duty component used by HVAC technicians and refrigeration service pros during line-set connections, system retrofits, and service repairs requiring a size transition between flared tubing ends.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial HVAC and refrigeration applications where a flare-to-flare size transition is required. It is commonly installed during line-set modifications, equipment changeouts, or service calls where existing tubing must connect to a different port size. The 45-degree flare seat profile provides a leak-resistant mechanical seal without solder or brazing, making it a quick-connect solution in appropriate low-pressure flare applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions from 1\/4 inch flare to 3\/8 inch flare in a single fitting\u003c\/li\u003e\n  \u003cli\u003eInternal flare to external flare configuration for direct inline connection\u003c\/li\u003e\n  \u003cli\u003e45-degree flare seat design provides a metal-to-metal leak-resistant seal\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.078 pounds for easy handling in tight spaces\u003c\/li\u003e\n  \u003cli\u003eNo solder or brazing required at the flare connection points\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fitting for residential and light commercial HVAC and refrigeration systems using standard 45-degree flare connections with 1\/4 inch and 3\/8 inch tubing ends.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or refrigeration mechanic. Always recover or isolate refrigerant and depressurize the line before disassembling or assembling flare fittings. Use a calibrated flare tool to ensure proper 45-degree flare geometry on the tubing ends before tightening. Do not overtighten flare nuts, as this can crack the flare seat and cause leaks.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecond Connection Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Flare\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecond End Type\u003c\/strong\u003e: Flare\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlare Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.078 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUniversal Category Code\u003c\/strong\u003e: UR3-64\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MUELLER INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MUE-A00479\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER INDUSTRIES","offers":[{"title":"Default Title","offer_id":51383255335218,"sku":"MUE-A00479","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670649.jpg?v=1782591237","url":"https:\/\/voomisupply.com\/products\/mueller-industries-mue-a00479-45-degree-flare-connector","provider":"Voomi Supply","version":"1.0","type":"link"}
