It splits a 10-inch main duct into two 8-inch branch legs, allowing balanced air distribution across multiple zones or supply runs. Fabricated from hot-dip galvanized steel, this fitting resists corrosion and holds up in both conditioned and unconditioned spaces. HVAC sheet metal contractors and mechanical tradespeople install this fitting during new construction duct fabrication or duct modification projects. It meets applicable ACCA and SMACNA standards for sheet metal ductwork construction.\u003c\/p\u003e\u003cp\u003eThis wye branch is suited for residential and light commercial forced-air systems where a 10-inch trunk line must divide into dual 8-inch supply or return branches. Typical install scenarios include attic, basement, and crawlspace duct runs where branch takeoffs are required to distribute conditioned air to multiple areas. The wye configuration provides a lower-resistance airflow path compared to sharp tee branch fittings, supporting more efficient air delivery across the system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHot-dip galvanized steel construction for corrosion resistance in HVAC duct applications\u003c\/li\u003e\n\u003cli\u003eWye branch configuration reduces turbulence and pressure drop compared to sharp tee fittings\u003c\/li\u003e\n\u003cli\u003e10-inch main inlet with dual 8-inch branch outlets for trunk-to-branch transitions\u003c\/li\u003e\n\u003cli\u003eMeets ACCA and SMACNA applicable standards for sheet metal duct systems\u003c\/li\u003e\n\u003cli\u003eSuitable for residential and light commercial forced-air ductwork installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style sheet metal wye branch fitting for residential and light commercial forced-air duct systems using 10-inch main trunk and 8-inch branch round duct configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed sheet metal or HVAC mechanical contractor in accordance with SMACNA duct construction standards and local mechanical codes. Power down the air handling unit and verify the system is depressurized before cutting into or modifying existing ductwork. Secure all connections with appropriate sheet metal screws and seal joints with listed duct sealant or foil tape per SMACNA guidelines. Do not rely on tape alone as the sole mechanical fastening method at the fitting joint.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMain Inlet Size\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBranch Outlet Size\u003c\/strong\u003e: 8 inches x 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SOUTHWARK METAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 78_10X8X8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284110770482,"sku":"78_10X8X8","price":34.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309276981.jpg?v=1781068782","url":"https:\/\/voomisupply.com\/products\/southwark-metal-78_10x8x8-sheet-metal-wye-branch-10x8x8","provider":"Voomi Supply","version":"1.0","type":"link"}
