It transitions from a 1-3\/8-inch fitting end down to a 7\/8-inch fitting end in a C x C (copper-to-copper) configuration. This type of fitting is a standard component in refrigeration, HVAC, and plumbing piping systems where line size reduction is required. Licensed plumbers and HVAC technicians install this fitting as part of new construction, retrofit, or repair work on copper piping systems.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for residential and light commercial applications where copper tubing must step down in diameter along a run. Common install scenarios include refrigerant line sets, hydronic heating systems, domestic water distribution, and drain or vent piping where copper is specified. The C x C end connections require standard soldering with appropriate flux and solder per local plumbing or mechanical code requirements. Sold in a box quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 1-3\/8 inches to 7\/8 inches in a single fitting\u003c\/li\u003e\n  \u003cli\u003eC x C (sweat) end connections for soldered copper-to-copper joints\u003c\/li\u003e\n  \u003cli\u003eCopper construction for corrosion resistance and solder compatibility\u003c\/li\u003e\n  \u003cli\u003eSold in box quantities of 10 for service stock or project use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sweat-connection fitting compatible with standard copper tubing in 1-3\/8-inch and 7\/8-inch nominal sizes, suitable for HVAC, refrigeration, and plumbing piping applications where a C x C reducing coupling is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or HVAC technician familiar with soldering copper fittings. Shut off and depressurize the system and purge any refrigerant or fluid before cutting into the line. Clean and flux both tube ends and the fitting sockets thoroughly before applying heat and solder per local mechanical or plumbing code requirements. Never solder near flammable materials without proper shielding, and allow the joint to cool fully before restoring system pressure.\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 (Sweat)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1-3\/8 inches x 7\/8 inches\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: 10\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: W1058\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NDL INDUSTRIES","offers":[{"title":"Default Title","offer_id":51383502438706,"sku":"W1058","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670844.jpg?v=1782598649","url":"https:\/\/voomisupply.com\/products\/ndl-industries-w1058-copper-reducing-coupling-1-3-8x7-8-cxc","provider":"Voomi Supply","version":"1.0","type":"link"}
