Constructed from hot dip galvanized steel, it resists corrosion in both supply and return air applications. The fitting ships without a crimp, giving installers the flexibility to crimp on-site to match the specific duct connection required. This reducer is a standard component used by HVAC technicians in residential and light commercial ductwork installations where airflow must be stepped down between trunk lines and branch runs.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for round duct systems in residential forced-air heating and cooling applications and light commercial HVAC installations. It is typically installed where a main duct trunk transitions to a smaller branch supply run. The 3-piece construction allows the fitting to maintain proper geometry through the transition, supporting balanced airflow distribution. HVAC installers working to ACCA and SMACNA standards will find this reducer consistent with those guidelines for round duct fabrication and installation practice.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions round duct from 6 inches to 4 inches 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\u003e3-piece design maintains geometric integrity through the diameter transition\u003c\/li\u003e\n  \u003cli\u003eNo crimp supplied — field crimp to match existing duct connections on-site\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards for round duct fittings\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 standard round sheet metal duct systems using 6-inch and 4-inch diameter duct pipe.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with SMACNA round duct standards. Power down the air handler and lock out the system before working on connected ductwork. Crimp the appropriate end on-site using sheet metal crimping tools before connecting to adjoining duct sections, and seal all joints with UL 181-rated duct sealant or foil tape per local mechanical code requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarger End Size\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmaller End Size\u003c\/strong\u003e: 4 inches\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 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_6X4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51283966034226,"sku":"58_6X4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277403.jpg?v=1781064446","url":"https:\/\/voomisupply.com\/products\/southwark-metal-58_6x4-sheet-metal-pipe-reducer-6x4","provider":"Voomi Supply","version":"1.0","type":"link"}
