Built without a crimped end, this fitting allows the installer to make the crimp in the field or mate directly to pre-crimped ductwork as needed. The shortway profile keeps the axial length compact at 4 inches overall, making it well suited for tight plenums or confined mechanical spaces. HVAC technicians and sheet metal installers use this type of reducer when stepping down supply or return air distribution runs to match downstream duct sizing.\u003c\/p\u003e\u003cp\u003eThis reducer is a standard component in residential and light commercial forced-air duct systems. It is typically installed where a main trunk or larger branch line must reduce to a smaller branch feeding a register boot, flex duct collar, or zone damper. The fitting weighs approximately 0.34 pounds and handles standard gage galvanized duct applications. It ships as a single-piece unit with no additional hardware required for basic slip-fit installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eShortway design with a compact 4-inch overall height for tight installation spaces\u003c\/li\u003e\n\u003cli\u003eTransitions 4-inch inside diameter duct to 3-inch inside diameter duct\u003c\/li\u003e\n\u003cli\u003eGalvanized steel construction resists corrosion in conditioned-air environments\u003c\/li\u003e\n\u003cli\u003eNo factory crimp allows field-formed connection on either end\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.34 pounds for easy single-hand handling during installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for standard round galvanized duct systems requiring a 4-inch to 3-inch shortway reduction without a factory crimp.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or sheet metal mechanic. Power down the air handler or furnace at the disconnect before working on duct connections. Secure the fitting with sheet metal screws and seal all joints with UL-listed duct sealant or approved foil tape in accordance with local mechanical codes. Do not overtighten sheet metal screws, as this can distort the fitting collar and compromise the air seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced Inside Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrimp\u003c\/strong\u003e: Without Crimp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.34 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40141700\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 45104030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718123422002,"sku":"45104030","price":39.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/880824b2c4bb3616ad9b26a45e55ee54.jpg?v=1788549982","url":"https:\/\/voomisupply.com\/products\/value-collection-45104030-galvanized-duct-reducer-4-to-3-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
