The fitting transitions from a 1\/2-inch line to a 1\/4-inch line in a single piece, eliminating the need for adapters or bushings. It is used in refrigeration, HVAC, and plumbing applications where a permanent, leak-tight reduction is required. Licensed plumbers, HVAC technicians, and refrigeration mechanics install this fitting as part of copper tubing assemblies in both new construction and retrofit work.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for residential and light commercial copper tubing systems where a sweat-solder joint is the specified connection method. Common applications include refrigerant line sets, domestic water supply piping, and hydronic systems that require a hard-copper reducing connection. The C x C end configuration means both the 1\/2-inch and 1\/4-inch sides accept copper tubing for a direct sweat joint with no threads involved. It is sold in a box quantity of 50 units, making it practical for contractors stocking a van or job-site supply.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCopper construction for corrosion resistance and reliable sweat-solder joints\u003c\/li\u003e\n  \u003cli\u003eReduces from 1\/2 inch to 1\/4 inch in one fitting with no additional hardware\u003c\/li\u003e\n  \u003cli\u003eC x C connection type on both ends for standard sweat-solder installation\u003c\/li\u003e\n  \u003cli\u003eAvailable in a 50-piece box quantity for contractor-level stocking\u003c\/li\u003e\n  \u003cli\u003eCompact reducing coupling profile suitable for tight installation spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style copper sweat fitting compatible with standard hard-drawn and annealed copper tubing conforming to ASTM B88 dimensions in 1\/2-inch and 1\/4-inch nominal sizes.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or HVAC-R technician following applicable local plumbing codes and IFGC or IPC requirements. Shut off the water or refrigerant supply and relieve system pressure before cutting into any existing line. Clean both the tubing ends and the fitting socket with emery cloth and apply flux before soldering to ensure a proper, void-free joint. Avoid overheating the fitting, as excessive heat can damage adjacent components and degrade the solder joint.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBasic Fitting Type\u003c\/strong\u003e: Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecific Fitting Type\u003c\/strong\u003e: Reducing Coupling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: C x C (Sweat)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1\/2 inch x 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBox Quantity\u003c\/strong\u003e: 50\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: NDL INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: W1021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NDL INDUSTRIES","offers":[{"title":"Default Title","offer_id":51383661101362,"sku":"W1021","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670842.jpg?v=1782603547","url":"https:\/\/voomisupply.com\/products\/ndl-industries-w1021-copper-reducing-coupling-1-2x1-4-cxc","provider":"Voomi Supply","version":"1.0","type":"link"}
