Fabricated from hot dip galvanized steel, this reducer delivers corrosion resistance suited for both supply and return duct applications. The no-crimp design means the fitting ships without a crimped end, allowing the installer to orient and prepare the connection as the job requires. HVAC sheet metal mechanics and ductwork installers are the primary trades working with this fitting on residential and light commercial air distribution systems.\u003c\/p\u003e\n\u003cp\u003eThis reducer is used where a main trunk or branch run steps down one pipe size, a common scenario when balancing airflow across multiple zones or transitioning between duct sections of differing diameters. It is appropriate for low-pressure forced-air supply and return duct assemblies in residential new construction, renovation, and equipment replacement work. The fitting meets ACCA and SMACNA fabrication and installation standards, making it suitable for jobs where code-compliant ductwork documentation is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions 10-inch diameter duct to 9-inch diameter duct in a single fitting\u003c\/li\u003e\n  \u003cli\u003eHot dip galvanized steel construction provides corrosion resistance for long service life\u003c\/li\u003e\n  \u003cli\u003e3-piece construction for consistent dimensional fit across the reducer body\u003c\/li\u003e\n  \u003cli\u003eNo-crimp end gives the installer flexibility to prepare the connection on site\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for forced-air duct systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for round sheet metal duct systems using 10-inch and 9-inch diameter pipe sections in residential and light commercial forced-air HVAC applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Power down the air handling unit and close the system before cutting into or modifying any duct section. Secure the reducer with sheet metal screws and seal all joints with mastic sealant or listed foil tape per SMACNA guidelines and local mechanical code requirements. Do not use standard duct tape as a primary sealant on pressure-tested duct systems.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarger End Size\u003c\/strong\u003e: 10 inches diameter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmaller End Size\u003c\/strong\u003e: 9 inches diameter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dip Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: 3-Piece\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCrimp Supplied\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: ACCA, SMACNA\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: SOUTHWARK METAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 58_10X9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283954794802,"sku":"58_10X9","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277446.jpg?v=1781064113","url":"https:\/\/voomisupply.com\/products\/southwark-metal-58_10x9-sheet-metal-pipe-reducer-10x9","provider":"Voomi Supply","version":"1.0","type":"link"}
