Sized at 1\/4 inch with a cup-by-cup (C x C) end connection, this coupling joins two lengths of copper tubing in a straight run without reducing flow diameter. Wrot copper construction provides high-pressure integrity and superior solderability compared to cast fittings. The compact profile suits tight-space applications common in refrigeration lines, domestic water supply, and hydronic heating systems. Licensed plumbers and HVAC technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for 1\/4 inch copper tube in low-pressure and high-pressure applications including ACR refrigerant lines, potable water distribution, and radiant heating loops. The C x C configuration requires a standard sweat-solder joint on both ends. It is sold individually with a minimum order quantity of 10 pieces, making it appropriate for service truck stock or small-batch repair work. No threaded or press-style adapters are needed when mating to standard 1\/4 inch copper tube.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWrot copper construction delivers consistent wall thickness and reliable solder joints\u003c\/li\u003e\n  \u003cli\u003eC x C end connections on both ends accept standard 1\/4 inch copper tube for sweat soldering\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch outside diameter matches standard 1\/4 inch nominal copper tube sizing\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.01 pounds — minimal added load in tight assemblies\u003c\/li\u003e\n  \u003cli\u003eStraight coupling profile maintains full bore flow without restriction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and general-use fitting compatible with standard 1\/4 inch nominal copper tube in sweat-solder applications across plumbing and HVAC refrigerant line installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or HVAC technicians using a tubing cutter, deburring tool, flux, and lead-free solder in compliance with applicable IPC and local plumbing codes. Cut tube ends must be deburred and cleaned, and appropriate flux applied before heating to ensure a full, void-free solder joint. Shut off and depressurize the system and drain standing water from the line before cutting into existing copper pipe. Do not use open-flame soldering near combustible materials without appropriate shielding in place.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: C x C (Sweat)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Wrot Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175305\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: BDNA-15731\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER INDUSTRIES","offers":[{"title":"Default Title","offer_id":51541520253234,"sku":"BDNA-15731","price":15.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f27114f1167866554723dbb79fae073f.jpg?v=1785878150","url":"https:\/\/voomisupply.com\/products\/mueller-industries-bdna-15731-wrot-copper-coupling-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
