It transitions from a 7\/8-inch connection to a 5\/8-inch connection, making it a standard component for reducing line size within refrigeration, HVAC, and plumbing systems. The all-copper construction ensures reliable soldered joints and long-term corrosion resistance. This fitting is installed by licensed HVAC technicians and plumbers during new construction, system modification, or repair work where a line-size reduction is required.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for residential and light commercial applications where copper tubing must be stepped down in diameter. Typical use cases include refrigerant line modifications, hydronic piping systems, and domestic water supply rough-in work. The C x C end configuration requires standard sweat soldering technique on both ends, making it compatible with the copper tubing and fitting methods used across HVAC and plumbing trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 7\/8-inch to 5\/8-inch copper tube diameter in a single fitting\u003c\/li\u003e\n  \u003cli\u003eC x C (sweat) connection on both ends for soldered installation\u003c\/li\u003e\n  \u003cli\u003eAll-copper construction for corrosion resistance and solder compatibility\u003c\/li\u003e\n  \u003cli\u003eCompact reducing coupling profile for tight-space installations\u003c\/li\u003e\n  \u003cli\u003eAvailable in a box quantity of 50 units for service truck or job-site stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard trade fitting for copper tube systems requiring a reduction from 7\/8-inch to 5\/8-inch diameter with sweat-soldered connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or HVAC technician following applicable local plumbing codes and IFGC or IPC requirements where relevant. Shut off and depressurize the system completely before cutting into any existing line. Clean and deburr both tube ends, apply flux, and solder all joints per standard sweat-soldering practice. Do not apply heat to the fitting while the system is pressurized or charged with refrigerant.\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: 7\/8 inches x 5\/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: W1036\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NDL INDUSTRIES","offers":[{"title":"Default Title","offer_id":51383548018994,"sku":"W1036","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670882.jpg?v=1782600146","url":"https:\/\/voomisupply.com\/products\/ndl-industries-w1036-copper-reducing-coupling-7-8x5-8-cxc","provider":"Voomi Supply","version":"1.0","type":"link"}
