It steps down from a 3\/8-inch line to a 5\/16-inch line and uses a copper x copper (C x C) connection type on both ends. The fitting is manufactured in a standard coupling profile for straightforward inline installation. Plumbers, HVAC technicians, and refrigeration technicians reach for this type of fitting when a diameter transition is required within a copper tube run.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for residential and light commercial applications where copper tube systems require a diameter change at a junction point. Typical install scenarios include hydronic systems, refrigerant line sets, domestic water distribution, and HVAC equipment connections. The C x C configuration requires proper flux application and soldering technique on both ends before making a permanent joint.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 3\/8 inches to 5\/16 inches in a single inline fitting\u003c\/li\u003e\n  \u003cli\u003eCopper x Copper (C x C) sweat connection on both ends\u003c\/li\u003e\n  \u003cli\u003eStandard reducing coupling profile for straightforward inline installation\u003c\/li\u003e\n  \u003cli\u003eSold in a box quantity of 50 units for shop stock or job-lot 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 compatible with 3\/8-inch to 5\/16-inch copper tube runs using sweat-end connections in plumbing, HVAC, and refrigeration applications.\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 codes and ASTM B88 copper tube standards. Shut off and depressurize the line before cutting into any existing system. Both ends require thorough cleaning, flux application, and proper silver or lead-free solder depending on the system type and local code requirements. Avoid overheating the fitting during soldering, as excessive heat can cause the copper to oxidize and compromise the 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 (Copper x Copper, Sweat)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3\/8 inches x 5\/16 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: W1010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NDL INDUSTRIES","offers":[{"title":"Default Title","offer_id":51383305961778,"sku":"W1010","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312669909.jpg?v=1782592864","url":"https:\/\/voomisupply.com\/products\/ndl-industries-w1010-copper-reducing-coupling-3-8x5-16-cxc","provider":"Voomi Supply","version":"1.0","type":"link"}
