Fabricated from hot dip galvanized steel, this no-crimp reducer provides a secure, corrosion-resistant connection between duct sections of different sizes. The 3-piece construction allows for straightforward field assembly and ensures a tight fit at both ends. Licensed HVAC technicians and sheet metal contractors install this fitting during trunk-and-branch duct system layout, air handler connections, and duct modification work in residential and light commercial applications.\u003c\/p\u003e\n\u003cp\u003eThis reducer is suited for residential and light commercial forced-air duct systems where a branch or main trunk line must be stepped down in diameter. It is commonly installed when transitioning from a main trunk to a smaller branch run, or when connecting an air handler outlet to a reduced-size supply duct. The no-crimp design means neither end requires additional crimping before connection, which simplifies installation when working with standard slip-and-drive or connector fittings. Fabrication meets ACCA and SMACNA standards, making it appropriate for systems built to those industry specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTransitions round duct from 8 inches to 5 inches in a single fitting\u003c\/li\u003e\n  \u003cli\u003eHot dip galvanized steel construction for corrosion resistance in conditioned and unconditioned spaces\u003c\/li\u003e\n  \u003cli\u003eNo-crimp ends on both the larger and smaller openings\u003c\/li\u003e\n  \u003cli\u003e3-piece design supports consistent field assembly and alignment\u003c\/li\u003e\n  \u003cli\u003eMeets ACCA and SMACNA applicable standards\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 requiring an 8-inch to 5-inch concentric reduction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or qualified sheet metal contractors. Power down and lock out the air handling unit before modifying any connected ductwork. Secure all joints with approved sheet metal screws and seal with mastic or UL 181-rated foil tape per SMACNA installation guidelines. Do not over-compress the fitting ends during assembly, as deformation can restrict airflow through the reducer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarger End Size\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmaller End Size\u003c\/strong\u003e: 5 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 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_8X5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SOUTHWARK METAL","offers":[{"title":"Default Title","offer_id":51284013023538,"sku":"58_8X5","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277410.jpg?v=1781066034","url":"https:\/\/voomisupply.com\/products\/southwark-metal-58_8x5-sheet-metal-pipe-reducer-8x5-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
