The small end is factory-crimped for easy insertion into the downstream duct section, allowing a secure, tool-minimal connection. At 6 inches in overall length, this reducer provides adequate overlap on both ends for a stable fit. HVAC installers and sheet metal mechanics use this fitting when downsizing trunk lines, branch runs, or perimeter loop systems in residential forced-air applications.\u003c\/p\u003e\n\u003cp\u003eThis reducer is suited for residential heating and cooling duct systems where round galvanized pipe is used for perimeter or radial duct layouts. It is appropriate for single-wall round duct only and is not rated for double-wall or insulated flex duct terminations. Typical installations include basement or crawlspace perimeter systems, attic radial runs, and supply branch reductions where a larger trunk feeds a smaller outlet collar. The crimped small end seats directly into the female end of the next duct section without additional fabrication.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces 5-inch round duct to 4-inch round duct in a single fitting\u003c\/li\u003e\n  \u003cli\u003e24-gauge galvanized steel construction resists corrosion in unconditioned spaces\u003c\/li\u003e\n  \u003cli\u003eFactory-crimped small end allows direct insertion into downstream duct section\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length provides overlap on both the large and small ends\u003c\/li\u003e\n  \u003cli\u003eDesigned for single-wall round perimeter pipe only\u003c\/li\u003e\n  \u003cli\u003eSold individually  -  one reducer per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style fitting for single-wall galvanized round duct systems in residential forced-air HVAC applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or sheet metal mechanic. Power down the air handling unit and close the system dampers before modifying ductwork. Secure both ends of the reducer with sheet metal screws and seal all joints with UL 181-listed foil tape or duct mastic per local mechanical code requirements. Do not use this fitting on double-wall, flexible, or lined duct without verifying compatibility with the duct system manufacturer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGauge\u003c\/strong\u003e: 24 Ga.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Treatment\u003c\/strong\u003e: Crimped small end\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Type\u003c\/strong\u003e: Single wall round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.61 pounds\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: IMPERIAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GV1416\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPERIAL","offers":[{"title":"Default Title","offer_id":68060774105394,"sku":"GV1416","price":25.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e3f548ee46e716636833ace3fc63cb3d_c1385bf4-d7f9-4a36-8a3e-dec1986973db.jpg?v=1793037284","url":"https:\/\/voomisupply.com\/products\/imperial-gv1416-galvanized-round-duct-reducer-5x4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
