It steps down from a 1\/2-inch connection to a 1\/4-inch connection using a solder-style C x C (cup-by-cup) end configuration. At 0.03 pounds and 1.08 inches in length, this compact fitting is built for tight spaces and high-volume service work. It meets ASME and NSF standards, making it suitable for potable water systems and general plumbing applications. Licensed plumbers and HVAC technicians install this fitting during new construction, remodel work, and equipment service calls where copper line size transitions are required.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is used in residential and light commercial plumbing and refrigeration systems wherever a copper tube run must transition from 1\/2-inch to 1\/4-inch tubing. Common applications include supply line reductions, equipment connections, and branch line transitions in copper hydronic and domestic water systems. Its wrot construction provides consistent wall thickness and reliable joint integrity when properly soldered or brazed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 1\/2-inch to 1\/4-inch in a single fitting, eliminating the need for multiple adapters\u003c\/li\u003e\n  \u003cli\u003eWrot copper construction delivers uniform wall thickness and strong, leak-resistant soldered joints\u003c\/li\u003e\n  \u003cli\u003eC x C end connections accept standard copper tube for sweat soldering or brazing\u003c\/li\u003e\n  \u003cli\u003eMeets ASME and NSF standards, approved for use in potable water systems\u003c\/li\u003e\n  \u003cli\u003eCompact profile at 1.08 inches in length suits confined installation spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-service fitting for copper tube systems requiring an inline 1\/2-inch to 1\/4-inch C x C reducing connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or HVAC technician using standard sweat-soldering or brazing procedures. Shut off and depressurize the water or refrigerant line and allow all components to cool completely before cutting and fitting the coupling. Clean and flux both tube ends per ASTM and local code requirements before applying heat. Follow applicable IPC and IFGC code sections for joint preparation, material compatibility, and inspection requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Wrot Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1\/2 x 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: C x C (Cup x Cup)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Length\/Depth\u003c\/strong\u003e: 1.08 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Height\u003c\/strong\u003e: 0.71 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Width\u003c\/strong\u003e: 0.71 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Weight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards \/ Compliance\u003c\/strong\u003e: ASME, NSF\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 STREAMLINE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CPL00478\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51524860608818,"sku":"CPL00478","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/21f97f2d8bcba265d99d8b3d40fa2265.webp?v=1785459862","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-cpl00478-reducing-coupling-1-2x1-4-cxc","provider":"Voomi Supply","version":"1.0","type":"link"}
