The tape carries a UL181B-FX Listing, making it code-compliant for use on Class 1 flexible air connectors. The high-deposition mastic adhesive creates a water-resistant bond that holds up under the temperature cycling and pressure variations typical of residential and light commercial ductwork. HVAC technicians and sheet metal contractors reach for this tape when a durable, listed foil seal is required by local mechanical code or job specification.\u003c\/p\u003e\n\u003cp\u003eThis tape is used in residential and commercial HVAC installations for sealing longitudinal seams, end joints, and repairs on flexible duct systems and duct board assemblies. The 3 inch width provides good coverage across duct seams and irregular surfaces, and the 33.33 yard roll length suits single-job or multi-joint applications. The silver aluminum foil facing reflects heat and resists moisture intrusion, which is especially relevant in unconditioned spaces such as attics, crawlspaces, and mechanical rooms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUL181B-FX Listed for use on Class 1 flexible air connectors and duct board\u003c\/li\u003e\n  \u003cli\u003e2.0 mil aluminum foil construction provides durability and heat reflectivity\u003c\/li\u003e\n  \u003cli\u003eHigh-deposition mastic adhesive delivers strong, water-resistant bond\u003c\/li\u003e\n  \u003cli\u003e3 inch width suits standard duct seam and joint sealing applications\u003c\/li\u003e\n  \u003cli\u003e33.33 yard roll length reduces roll changes on larger jobs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on UL181B-rated flexible air connectors and duct board assemblies where a UL181B-FX Listed foil tape is specified or required by mechanical code.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician or sheet metal contractor in accordance with the International Mechanical Code and applicable local codes. Shut down the air handling system before applying tape to duct seams or joints. Clean and dry all surfaces before application to ensure full adhesive contact. Do not stretch the tape during application, as this can reduce bond integrity at seam edges.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTape Thickness\u003c\/strong\u003e: 2.0 mil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 33.33 yards\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdhesive Type\u003c\/strong\u003e: Mastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFacing Material\u003c\/strong\u003e: Aluminum foil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eListing\u003c\/strong\u003e: UL181B-FX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 48 pounds\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: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100043954\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344899309874,"sku":"7100043954","price":1350.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310523900.jpg?v=1782044876","url":"https:\/\/voomisupply.com\/products\/3m-7100043954-venture-tape-1580-p-foil-tape-3-in-x-33-yd","provider":"Voomi Supply","version":"1.0","type":"link"}
