At 3.75 inches in overall height, this compact fitting delivers a clean, direct reduction in a short run — useful in tight mechanical spaces where a standard long reducer will not fit. The fitting weighs 0.5 pounds and is fabricated from galvanized steel to resist corrosion in typical HVAC duct environments. HVAC technicians and sheet metal installers use this type of fitting to reduce trunk-to-branch duct runs or to adapt between fan outlet collars and smaller flex or rigid duct sections.\u003c\/p\u003e\u003cp\u003eThis shortway reducer without crimp is suited for residential and light commercial forced-air HVAC ductwork installations. The uncrimped end allows the installer to choose their own slip joint orientation or to crimp the end in the field to match existing system connections. It is appropriate for supply or return duct applications where a concentric round reduction is needed between two standard duct diameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-inch inside diameter inlet reduces to 4-inch inside diameter outlet\u003c\/li\u003e\n\u003cli\u003e3.75-inch overall height keeps the transition compact in confined spaces\u003c\/li\u003e\n\u003cli\u003eGalvanized steel construction resists corrosion in conditioned-air duct systems\u003c\/li\u003e\n\u003cli\u003eShortway design minimizes static pressure loss in short-run transitions\u003c\/li\u003e\n\u003cli\u003eUncrimped ends allow field customization of slip joint direction\u003c\/li\u003e\n\u003cli\u003eWeighs 0.5 pounds for easy single-tech handling during overhead or crawlspace installs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-installation fitting for residential and light commercial round galvanized duct systems requiring a 5-inch to 4-inch concentric reduction.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or sheet metal installer. Power down the air handling unit and confirm the system is de-energized before working on ductwork connections. Secure all slip joints with sheet metal screws and seal seams with UL 181-listed duct tape or mastic per applicable mechanical codes. Do not overtighten sheet metal screws on the galvanized collar, as this can distort the fitting 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: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced Inside Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Shortway Reducer Without Crimp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: 45105040\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711227560242,"sku":"45105040","price":41.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d86969cb26e65feefd09566297a3e0b.jpg?v=1788475003","url":"https:\/\/voomisupply.com\/products\/value-collection-45105040-duct-shortway-reducer-5-to-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
