Fabricated from hot dip galvanized steel, this reducer delivers corrosion resistance suited for residential and light commercial HVAC duct systems. The no-crimp design means the fitting ships without a pre-formed crimp end, which is standard practice for certain field-assembled duct runs where the installer crimps on-site or uses alternative joining methods. It meets ACCA and SMACNA standards for sheet metal ductwork fabrication.\u003c\/p\u003e\n\u003cp\u003eThis reducer is used in forced-air HVAC systems wherever a main trunk or branch run needs to step down from 9-inch to 7-inch round duct. Typical applications include residential trunk-and-branch layouts, commercial light-duty air distribution systems, and retrofit duct modifications where airflow needs to be directed into a smaller-diameter run. Sheet metal contractors and HVAC installers are the primary trades that work with this fitting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions round duct from 9 inches to 7 inches in a single fitting\u003c\/li\u003e\n  \u003cli\u003e3-piece construction for consistent dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eHot dip galvanized steel for corrosion resistance in duct environments\u003c\/li\u003e\n  \u003cli\u003eNo-crimp end — installer crimps in the field as needed\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA standards for sheet metal duct fabrication\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 9-inch and 7-inch diameter connections, per SMACNA and ACCA duct construction standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSheet metal contractors and HVAC technicians install this reducer as part of a round duct system. Shut down the air handling unit and disconnect power before modifying any section of an active duct run. Secure the fitting with sheet metal screws and seal all joints with mastic sealant or UL 181-listed foil tape per SMACNA installation guidelines. Because this fitting ships without a crimp, field-crimp the appropriate end using a hand crimper before inserting into the adjoining duct section if the installation requires a slip joint.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarger End Size\u003c\/strong\u003e: 9 inches diameter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmaller End Size\u003c\/strong\u003e: 7 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_9X7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284140622130,"sku":"58_9X7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277444.jpg?v=1781069609","url":"https:\/\/voomisupply.com\/products\/southwark-metal-58_9x7-sheet-metal-pipe-reducer-9x7-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
