The tape features a high-tack acrylic adhesive that bonds to rigid and flexible duct surfaces to form an airtight, moisture-resistant seal. At 17 mil total thickness, it delivers durable performance across a wide operating temperature range of -20 degrees F to 260 degrees F. Adhesion to steel is rated near 60 oz\/in. Each roll is 2 inches wide and 60 yards long. Licensed HVAC technicians and sheet metal mechanics install this tape to meet code-compliant duct sealing requirements on commercial and residential jobs.\u003c\/p\u003e\n\u003cp\u003eThis tape is used on rigid fiberglass duct board, rigid sheet metal ductwork, and flexible duct connections where a UL181B-FX listed sealant tape is required by mechanical code. It is well suited for sealing longitudinal seams, transverse joints, and duct-to-fitting connections. The mastic-coated foil backing conforms to irregular surfaces and resists moisture intrusion, making it appropriate for both conditioned space and unconditioned space duct installations 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 code-compliant sealing of rigid and flexible duct systems\u003c\/li\u003e\n  \u003cli\u003e17 mil total thickness provides robust, puncture-resistant coverage over duct joints and seams\u003c\/li\u003e\n  \u003cli\u003eHigh-tack acrylic adhesive with approximately 60 oz\/in adhesion to steel\u003c\/li\u003e\n  \u003cli\u003eMastic-coated aluminum foil backing creates an airtight and moisture-resistant bond\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -20 degrees F to 260 degrees F suits a wide range of HVAC applications\u003c\/li\u003e\n  \u003cli\u003e2-inch width, 60-yard roll length for efficient coverage on large duct sealing projects\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a UL181B-FX listed sealant tape for use on rigid fiberglass duct board systems and flexible duct connections in residential and commercial HVAC installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or sheet metal mechanic. Shut down the air handling system and depressurize the duct before applying tape to joints or seams. Surfaces should be clean, dry, and free of dust or grease for proper adhesion. Refer to local mechanical codes and the International Mechanical Code for duct sealing requirements specific to the system type and application.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUL Listing\u003c\/strong\u003e: UL181B-FX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Thickness\u003c\/strong\u003e: 17 mil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoll Length\u003c\/strong\u003e: 60 yards\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdhesion to Steel\u003c\/strong\u003e: approximately 60 oz\/in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range\u003c\/strong\u003e: -20 degrees F to 260 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Mastic-coated aluminum foil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdhesive Type\u003c\/strong\u003e: High-tack acrylic\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: VYBOND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 36717A2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VYBOND","offers":[{"title":"Default Title","offer_id":51344143417650,"sku":"36717A2","price":55.29,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552720.jpg?v=1782030141","url":"https:\/\/voomisupply.com\/products\/vybond-36717a2-foilmastic-ul181b-fx-duct-sealant-tape","provider":"Voomi Supply","version":"1.0","type":"link"}
