Flexible metallic duct is a core component in residential and light commercial HVAC installations, used to connect rigid ductwork to diffusers, grilles, and air handlers where a rigid connection is impractical. The aluminum construction provides durability and resistance to moisture, making it suitable for supply and return air applications in conditioned spaces. HVAC technicians and sheet metal contractors install this product as part of forced-air distribution systems.\u003c\/p\u003e\u003cp\u003eThis flexible duct section is used in residential heating, cooling, and ventilation systems where a 3-inch diameter connection is required. Common applications include branch runs from a plenum or trunk line to individual supply outlets, as well as connections to bathroom exhaust fans and range hood venting where flexible metal duct is code-approved. The 25-foot length provides enough material to complete multiple short branch runs or a single longer run without splicing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-inch diameter for standard branch duct connections and exhaust fan terminations\u003c\/li\u003e\n\u003cli\u003e25-foot length reduces the need for couplings or splicing on longer runs\u003c\/li\u003e\n\u003cli\u003eAluminum construction resists corrosion and moisture in conditioned and semi-conditioned spaces\u003c\/li\u003e\n\u003cli\u003eFlexible design allows routing around framing members and obstructions without rigid fittings\u003c\/li\u003e\n\u003cli\u003eMetallic construction meets code requirements where non-metallic duct is not permitted\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style flexible duct section suitable for 3-inch diameter HVAC branch runs, exhaust fan connections, and ventilation applications in residential and light commercial forced-air systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or sheet metal contractors following local mechanical codes and ASHRAE duct design guidelines. Power down the air handling unit before connecting or disconnecting duct sections. Secure each end with an approved draw band or worm-gear clamp and seal with listed foil tape or mastic sealant. Avoid sharp bends or excessive compression of the duct, as both reduce airflow and system efficiency.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 25 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Type\u003c\/strong\u003e: Flexible Metallic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DEFLECTO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FLS-0325\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DEFLECTO","offers":[{"title":"Default Title","offer_id":51347312705842,"sku":"FLS-0325","price":30.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553367.jpg?v=1782101190","url":"https:\/\/voomisupply.com\/products\/deflecto-fls-0325-flexible-metallic-duct-3-in-25-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
