Joining a 5\/8-inch socket to a 3\/8-inch socket with a C x C (copper-to-copper) connection type, this fitting allows plumbers and HVAC technicians to step down tubing size within a refrigerant, potable water, or hydronic line. The all-copper construction provides corrosion resistance and reliable soldered joints under typical service pressures. It is sold in a box quantity of 100, making it practical for contractors stocking a service vehicle or completing multi-fixture roughed-in work.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for residential and light commercial plumbing and HVAC applications where a transition from 5\/8-inch to 3\/8-inch copper tubing is required. Common install scenarios include domestic water supply lines, refrigerant distribution piping, and hydronic heating loops. The sweat-connect design is standard practice for licensed plumbers and HVAC mechanics working with hard copper tubing in new construction and retrofit projects alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 5\/8-inch to 3\/8-inch copper tube in a single fitting\u003c\/li\u003e\n  \u003cli\u003eC x C connection type for sweat-soldered joints on both ends\u003c\/li\u003e\n  \u003cli\u003eAll-copper construction for corrosion resistance in water and refrigerant service\u003c\/li\u003e\n  \u003cli\u003eSold in a box quantity of 100 for contractor-level supply\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style sweat-fit reducing coupling compatible with standard 5\/8-inch and 3\/8-inch hard copper tubing per ASTM B88 and B280 specifications in plumbing and HVAC 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 plumbing codes and IFGC or IPC guidelines. Shut off and depressurize the water or refrigerant system completely before cutting into any existing line. Clean the tube ends and fitting sockets thoroughly and apply flux before soldering to ensure a leak-free joint. Allow soldered joints to cool fully before pressurizing the system.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 5\/8 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: W1025\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NDL INDUSTRIES","offers":[{"title":"Default Title","offer_id":51383968366898,"sku":"W1025","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670850.jpg?v=1782613539","url":"https:\/\/voomisupply.com\/products\/ndl-industries-w1025-copper-reducing-coupling-5-8x3-8-cxc","provider":"Voomi Supply","version":"1.0","type":"link"}
