It transitions from a 3\/4-inch line to a 3\/8-inch line without the need for additional adapters. This fitting is used in potable water supply, hydronic heating, refrigeration, and HVAC piping systems. Plumbers and HVAC technicians install this type of fitting wherever a line size reduction is required in an all-copper system. The sweat-connect ends accept standard copper tubing and are joined using a torch and appropriate solder or brazing alloy.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for residential and light commercial plumbing and mechanical systems where a permanent, leak-tight inline reduction is needed. Typical applications include domestic hot and cold water distribution, chilled water piping, and refrigerant line connections requiring a size step-down. It is sold in a box quantity of 100 units, making it appropriate for contractors managing multi-fixture or multi-unit projects.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 3\/4-inch to 3\/8-inch in a single inline fitting\u003c\/li\u003e\n  \u003cli\u003eC x C (sweat) connection on both ends for a soldered or brazed joint\u003c\/li\u003e\n  \u003cli\u003eCopper construction compatible with standard torch-and-solder installation\u003c\/li\u003e\n  \u003cli\u003eInline coupling profile eliminates need for a separate reducer bushing\u003c\/li\u003e\n  \u003cli\u003eBox quantity of 100 units suits contractor-volume purchasing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-use fitting for copper piping systems using 3\/4-inch and 3\/8-inch nominal tube sizes with sweat (C x C) end connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or qualified HVAC technician following applicable IPC or IFGC requirements. Shut off and depressurize the water or refrigerant system and allow all lines to cool before cutting into existing piping. Clean pipe ends and fitting sockets thoroughly with emery cloth and apply appropriate flux before soldering or brazing. Do not apply heat to a pressurized line.\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: 3\/4 inches x 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBox Quantity\u003c\/strong\u003e: 100\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: W1031\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NDL INDUSTRIES","offers":[{"title":"Default Title","offer_id":51383716806962,"sku":"W1031","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312669950.jpg?v=1782605348","url":"https:\/\/voomisupply.com\/products\/ndl-industries-w1031-copper-reducing-coupling-3-4x3-8-cxc","provider":"Voomi Supply","version":"1.0","type":"link"}
