It transitions a 3\/4-inch line down to a 1\/2-inch line using a C x C (cup by cup) end configuration, making it a standard fitting for reducing runs in residential and light commercial water supply and hydronic distribution lines. At 0.08 pounds and compact dimensions, it is easy to handle in tight spaces. Compliance with ASME and NSF standards confirms suitability for potable water service. Licensed plumbers and pipefitters are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is used in new construction and retrofit plumbing projects where a copper tubing run must step down from 3\/4-inch to 1\/2-inch diameter. Typical applications include domestic hot and cold water distribution, hydronic heating branch lines, and in-wall or under-slab rough-in work where a direct solder joint is required. The wrot copper construction provides consistent wall thickness and reliable joint integrity when properly sweated.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWrot copper construction for consistent wall thickness and strong soldered joints\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch by 1\/2-inch reducing configuration for common step-down runs\u003c\/li\u003e\n  \u003cli\u003eC x C (cup by cup) ends accept standard copper tubing for sweat installation\u003c\/li\u003e\n  \u003cli\u003eASME and NSF compliant for use in potable water systems\u003c\/li\u003e\n  \u003cli\u003eCompact profile at 1.49 inches length and 0.97 inches width for tight-space installations\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.08 pounds for easy single-hand handling during installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sweat fitting for standard copper tubing systems following ASME and NSF requirements; suitable for 3\/4-inch by 1\/2-inch C x C reducing applications in potable water and hydronic piping.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with the applicable International Plumbing Code (IPC) or local plumbing code requirements. Shut off and depressurize the water supply line and allow all moisture to drain completely before soldering, as residual water prevents proper joint formation. Clean both the tubing ends and fitting cups with emery cloth and apply lead-free flux before soldering with a lead-free solder approved for potable water service. Allow the joint to cool fully before restoring pressure and inspecting for leaks.\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: 3\/4 x 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: C x C (Cup by Cup)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Length\/Depth\u003c\/strong\u003e: 1.49 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Width\u003c\/strong\u003e: 0.97 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Height\u003c\/strong\u003e: 0.97 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Weight\u003c\/strong\u003e: 0.08 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: CPL00307\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51524581097778,"sku":"CPL00307","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d7baff5cd8ca321ceef5234928b46b6.webp?v=1785452334","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-cpl00307-copper-reducing-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
