It features three solder-joint (C-type) connections: two 3-inch run connections and one 3\/4-inch branch connection. This configuration allows a main 3-inch line to feed a reduced 3\/4-inch branch without additional reducers. The fitting is manufactured from copper, making it suitable for potable water, hot water heating, and refrigerant-adjacent piping where copper is specified. Licensed plumbers and HVAC technicians are the primary installers of this fitting.\u003c\/p\u003e\u003cp\u003eThis tee is used in residential and light commercial plumbing and mechanical systems where a 3-inch copper main line requires a 3\/4-inch branch takeoff. Common install scenarios include hot and cold water distribution mains, hydronic heating supply and return headers, and domestic water service lines. The reduced branch outlet makes it well-suited for feeding fixture branches or zone lines off a larger trunk line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThree solder-cup (sweat) connections for leak-free, soldered joints\u003c\/li\u003e\n\u003cli\u003e3 in x 3\/4 in x 3 in configuration for reduced-branch tee applications\u003c\/li\u003e\n\u003cli\u003eCopper construction compatible with potable water and heating systems\u003c\/li\u003e\n\u003cli\u003eOEM-style dimensions for standard copper sweat fitting installations\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 1 unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for copper sweat piping systems using standard C-type (solder-cup) connections in 3-inch and 3\/4-inch copper pipe sizes.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with the applicable International Plumbing Code (IPC) or local jurisdiction requirements. Shut off and drain the water supply completely before cutting into an existing line. Clean and flux all pipe ends and fitting cups thoroughly before soldering; use a propane or MAP-gas torch appropriate for the pipe diameter. Allow joints to cool fully before restoring system pressure and inspecting for leaks.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: C (Sweat\/Solder)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 1 (Run)\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 2 (Branch)\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size 3 (Run)\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.47 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MIDLAND INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 77583\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67951979397426,"sku":"77583","price":211.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ceadde3882f46bfd1221304a46ff753_f621cd86-9d12-4f64-b2bb-fa6c2290cd74.jpg?v=1791743166","url":"https:\/\/voomisupply.com\/products\/midland-industries-77583-copper-sweat-tee-3x3-4x3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
