Built from heavy-duty galvanized steel, the 301-12 features a precision-engineered collar that maintains an airtight seal at the connection point, reducing conditioned air loss and supporting balanced airflow throughout the system. This fitting is installed by HVAC technicians during new construction, renovation, or duct replacement work in both residential and commercial applications. The galvanized steel construction resists corrosion, making it suited for long-term service in attics, crawlspaces, basements, and mechanical rooms.\u003c\/p\u003e\n\u003cp\u003eThe 301-12 is intended for 12-inch round duct branch takeoff applications. It is appropriate for supply-side duct systems where a lateral branch connection must be made from a main trunk line. Typical installations include forced-air heating and cooling systems in residential homes and light commercial buildings where controlled airflow to individual zones or rooms is required. The airtight collar design helps prevent the pressure losses associated with poorly fitted duct connections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFits 12-inch round duct connections for branch takeoff applications\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty galvanized steel construction resists corrosion and physical damage\u003c\/li\u003e\n  \u003cli\u003ePrecision-engineered collar promotes an airtight seal to minimize conditioned air loss\u003c\/li\u003e\n  \u003cli\u003eConsistent fit supports balanced air distribution across duct systems\u003c\/li\u003e\n  \u003cli\u003eSuitable for both residential and light commercial forced-air HVAC installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style duct fitting for 12-inch round duct branch takeoff applications in residential and commercial forced-air HVAC 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 local mechanical codes and SMACNA duct construction standards. Shut down the air handling unit and verify the system is depressurized before cutting into the main trunk line. Secure the takeoff collar with sheet metal screws and seal all edges with UL 181-rated foil tape or mastic sealant to maintain system integrity. Do not operate the system until all connections are fully sealed and inspected.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Size\u003c\/strong\u003e: 12 inches round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Galvanized steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Airtite collar takeoff\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Forced-air duct branch connection, residential and commercial\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: SEAL-TITE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 301-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SEAL-TITE","offers":[{"title":"Default Title","offer_id":51345857478962,"sku":"301-12","price":28.64,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554967.jpg?v=1782064796","url":"https:\/\/voomisupply.com\/products\/seal-tite-301-12-airtite-duct-takeoff-12-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
