Fabricated from hot dipped galvanized steel, this reducer delivers corrosion resistance suitable for residential and light commercial forced-air HVAC systems. The 3-piece construction allows for field adjustment and easier installation in tight spaces. HVAC technicians and sheet metal contractors install this fitting as part of supply or return trunk-line reductions where duct sizing must step down to match branch runs or terminal equipment.\u003c\/p\u003e\n\u003cp\u003eThis reducer is used in ducted forced-air heating and cooling systems where airflow must be transitioned between trunk and branch duct segments. Typical applications include supply-side trunk reductions in residential furnace and air handler installations, as well as light commercial air distribution systems requiring a concentric round-to-round step-down fitting. The fitting conforms to ACCA and SMACNA standards, making it appropriate for systems designed and installed to current industry guidelines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions from 12-inch diameter to 9-inch diameter round duct\u003c\/li\u003e\n  \u003cli\u003eHot dipped galvanized steel construction for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e3-piece design allows for field adjustment during installation\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards\u003c\/li\u003e\n  \u003cli\u003eRound profile fits standard round duct and fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard fitting for round sheet metal duct systems with a 12-inch large-end connection and a 9-inch small-end connection, conforming to ACCA and SMACNA standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal contractor following SMACNA duct construction standards. Power down the air handling unit and verify the system is de-energized before beginning duct work. Secure the reducer to adjoining duct sections using sheet metal screws and seal all joints with UL 181-listed duct sealant or approved tape per local mechanical code requirements. No crimp is supplied with this fitting, so verify end-connection method before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Hot Dipped Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: 3-Piece, Round\u003c\/li\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: 9 inches diameter\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_12X9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284135903538,"sku":"58_12X9","price":23.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277431.jpg?v=1781069455","url":"https:\/\/voomisupply.com\/products\/southwark-metal-58_12x9-round-duct-reducer-12-to-9-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
