With a 7\/8-inch by 3\/8-inch connection size and a sweat-solder (C X C) fitting type, this coupling allows a technician to step down tubing size within a refrigerant, hydronic, or potable water line without the need for an adapter or union. It is installed by licensed HVAC technicians, plumbers, and refrigeration mechanics wherever a direct copper-to-copper size transition is required.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for residential and light commercial applications including refrigerant line sets, chilled water piping, domestic hot and cold water distribution, and radiant heating systems. The C X C end configuration requires both male ends to be cleaned, fluxed, and brazed or soldered to the female socket ends of the fitting. It ships in a box quantity of 50 units, making it practical for stocking on service vehicles or in shop inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCopper construction for compatibility with refrigerant, hydronic, and potable water service\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch by 3\/8-inch reducing configuration for inline diameter transitions\u003c\/li\u003e\n  \u003cli\u003eC X C sweat-solder end connections for a leak-tight brazed or soldered joint\u003c\/li\u003e\n  \u003cli\u003eAvailable in a 50-piece box quantity for shop and truck stocking\u003c\/li\u003e\n  \u003cli\u003eInline coupling profile keeps the fitting compact within tight mechanical chases\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for copper tubing systems requiring a 7\/8-inch to 3\/8-inch inline size reduction with sweat-solder end connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber, HVAC technician, or refrigeration mechanic. Shut off and isolate the fluid or refrigerant circuit and allow the line to depressurize fully before cutting into existing copper tubing. Both tubing ends must be cut square, deburred, cleaned with emery cloth, and coated with the appropriate flux before insertion into the coupling sockets. Follow applicable codes including IPC, IFGC, or applicable mechanical codes for brazing and soldering procedures.\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\u003eFitting Connection Type\u003c\/strong\u003e: C X C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 7\/8 inches X 3\/8 inches\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: W1038\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NDL INDUSTRIES","offers":[{"title":"Default Title","offer_id":51383435788594,"sku":"W1038","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670883.jpg?v=1782596521","url":"https:\/\/voomisupply.com\/products\/ndl-industries-w1038-copper-reducing-coupling-7-8x3-8-cxc","provider":"Voomi Supply","version":"1.0","type":"link"}
