Constructed from metalized polyester, this uninsulated flex duct provides a lightweight, packable form factor that allows technicians to route airflow through tight chases, angled transitions, and confined mechanical spaces. At 25 feet in length, a single roll covers most branch-run and air-connector applications without splicing. The flexible construction makes field installation fast while maintaining consistent cross-sectional area through bends and offsets.\u003c\/p\u003e\n\u003cp\u003eThis duct is suited for use as a short air connector between rigid metal ductwork and diffusers, registers, or terminal units in forced-air systems. It is commonly installed in residential attics, crawlspaces, dropped ceilings, and utility rooms where routing flexibility is needed. Applications include supply-air branch runs off main trunk lines and connections to ceiling diffusers in light commercial HVAC systems. Consult local mechanical codes to confirm where uninsulated flexible duct is permitted in your jurisdiction before installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMetalized polyester construction provides a flexible, corrosion-resistant air pathway\u003c\/li\u003e\n  \u003cli\u003e3-inch diameter suits standard small-branch supply runs and air-connector applications\u003c\/li\u003e\n  \u003cli\u003e25-foot length covers most single branch-run installations without field splicing\u003c\/li\u003e\n  \u003cli\u003eUninsulated design keeps weight low and simplifies routing in space-constrained areas\u003c\/li\u003e\n  \u003cli\u003eFlexible body navigates bends and offsets without collapsing the cross-section\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style air connector for use with 3-inch collar fittings in residential and light commercial forced-air HVAC duct systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician in accordance with SMACNA guidelines and applicable local mechanical codes. Shut down the air-handling unit and confirm the system is de-energized before connecting or disconnecting ductwork. Avoid sharp bends that reduce the internal diameter or restrict airflow; manufacturers and codes generally limit flex duct to the minimum bend radius that maintains the rated cross-section. Secure both ends with approved clamps or draw bands and seal with listed mastic or metal-backed tape per code requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: Metalized Polyester\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Type\u003c\/strong\u003e: Flex Duct\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSub Type\u003c\/strong\u003e: Air Connector\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation\u003c\/strong\u003e: Uninsulated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.6 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 30 x 30 x 30 inches\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: HART COOLEY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5502503\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HART \u0026 COOLEY","offers":[{"title":"Default Title","offer_id":51619772039474,"sku":"05502503","price":30.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2945d1f966512f511eadb0a3ab76cecb.jpg?v=1787334111","url":"https:\/\/voomisupply.com\/products\/hart-cooley-5502503-flexible-foil-duct-3-in-25-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
