Fabricated from hot dip galvanized steel, this reducer delivers corrosion resistance suited to both supply and return air duct systems. The no-crimp design means the fitting ships without a pre-formed bead on the smaller end, allowing the installer to maintain full control over field connections and slip-joint fitment. HVAC sheet metal mechanics and ductwork installers handle this type of fitting in residential and light commercial forced-air systems.\u003c\/p\u003e\n\u003cp\u003eThis reducer is used wherever a round duct run steps down in diameter to balance airflow distribution across a duct system. Typical applications include trunk-to-branch transitions and inline diameter reductions in galvanized round duct systems. It is well-suited for new construction ductwork and retrofit work where an existing run must be reduced to feed a smaller downstream trunk or branch. The fitting meets ACCA and SMACNA applicable standards, making it appropriate for jobs where code-compliant duct construction is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions 12-inch round duct to 10-inch round duct in a single fitting\u003c\/li\u003e\n  \u003cli\u003eHot dip galvanized steel construction for corrosion resistance in duct environments\u003c\/li\u003e\n  \u003cli\u003eNo-crimp design gives installers full flexibility for field connections\u003c\/li\u003e\n  \u003cli\u003e3-piece construction for consistent dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for duct fabrication\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-construction fitting for standard 12-inch to 10-inch galvanized round duct systems built to ACCA and SMACNA specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal mechanics. Shut down the air handling system and de-energize the air handler before cutting into or modifying any duct section. Secure the reducer with sheet metal screws and seal all joints with listed duct sealant or UL 181-rated tape per SMACNA guidelines. Avoid over-driving screws into the galvanized material, which can compromise the protective coating at the connection point.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarger End Size\u003c\/strong\u003e: 12 inches diameter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmaller End Size\u003c\/strong\u003e: 10 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\u003eType\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 Standard\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_12X10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283964494130,"sku":"58_12X10","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277447.jpg?v=1781064390","url":"https:\/\/voomisupply.com\/products\/southwark-metal-58_12x10-sheet-metal-pipe-reducer-12-to-10-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
