Measuring 4 inches in diameter and 25 feet in length, this connector bridges equipment connections and transitions where rigid ductwork is impractical. Its metallic construction provides durability and resistance to crushing, making it suitable for exposed or semi-exposed installations. HVAC technicians and sheet metal contractors install this connector in both new construction and retrofit applications where flexible, uninsulated duct runs are required.\u003c\/p\u003e\u003cp\u003eThis connector is used in residential and light commercial HVAC systems to connect air handlers, furnaces, and branch takeoffs to supply or return grilles. The uninsulated design suits unconditioned spaces where a separate insulation wrap will be applied or where code does not require factory-applied insulation. At 25 feet per roll, a single unit covers most standard duct runs without splicing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-inch diameter fits standard HVAC collar and boot connections\u003c\/li\u003e\n\u003cli\u003e25-foot length provides sufficient run for most residential duct branch applications\u003c\/li\u003e\n\u003cli\u003eMetallic construction resists crushing and maintains airflow cross-section\u003c\/li\u003e\n\u003cli\u003eUninsulated design allows field-applied insulation wrap per local code requirements\u003c\/li\u003e\n\u003cli\u003ePart of the 06 Series flexible connector product line\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fit connector for 4-inch HVAC duct branch connections in residential and light commercial air distribution systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal contractor in accordance with local mechanical codes and SMACNA guidelines. Power down the air handling unit and shut off any associated heating equipment before making duct connections. Secure each end of the connector with an approved draw band or sheet metal screw to prevent pullout. Do not compress or sharply bend the connector, as restriction reduces airflow and can increase static pressure drop across the system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 25 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsulation\u003c\/strong\u003e: Uninsulated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Metallic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 06 Series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FLEXIBLE TECHNOLOGIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4MC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FLEXIBLE TECHNOLOGIES","offers":[{"title":"Default Title","offer_id":51342927364402,"sku":"4MC","price":42.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552822.png?v=1782010842","url":"https:\/\/voomisupply.com\/products\/flexible-technologies-4mc-metallic-flex-connector-4-in-x-25-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
