It features a metallic foil backing combined with a high-tack mastic adhesive layer that forms a durable, long-term air and vapor seal at duct joints, collars, and transitions. The tape measures 17 mil total thickness, delivers approximately 60 ounces per inch of adhesion to steel, and handles service temperatures from -20 degrees F to 260 degrees F. HVAC technicians use this tape as a code-compliant solution wherever UL181B-FX listed closure systems are required on flex duct installations.\u003c\/p\u003e\n\u003cp\u003eThis tape is suited for sealing flexible duct joints, end connections, and transition fittings in forced-air heating and cooling systems. The UL181B-FX listing makes it acceptable under mechanical codes that require listed closure systems on Class 1 flexible air ducts and air connectors. It is appropriate for residential retrofits and new construction installs where a permanent, pressure-sensitive metallic tape closure is specified. Each unit includes one 60-yard roll, providing substantial coverage for a full system installation or service run.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUL181B-FX listed for use on flexible duct systems requiring a code-compliant closure\u003c\/li\u003e\n  \u003cli\u003e17 mil total tape thickness for robust, tear-resistant handling during installation\u003c\/li\u003e\n  \u003cli\u003eHigh-tack mastic adhesive with approximately 60 oz\/in adhesion to steel\u003c\/li\u003e\n  \u003cli\u003eWide service temperature range: -20 degrees F to 260 degrees F\u003c\/li\u003e\n  \u003cli\u003eMetallic foil backing forms a durable air and vapor barrier at sealed joints\u003c\/li\u003e\n  \u003cli\u003e60-yard roll per unit provides generous coverage per job\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a UL181B-FX listed closure for Class 1 flexible air ducts and air connectors 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 applicable mechanical codes, including SMACNA guidelines and local authority having jurisdiction requirements. Power down the air handling system before accessing duct connections. Surfaces must be clean, dry, and free of dust or grease for the adhesive to bond correctly. Do not stretch the tape during application, as distortion can reduce adhesion and compromise the seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eListing\u003c\/strong\u003e: UL181B-FX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Metallic foil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Thickness\u003c\/strong\u003e: 17 mil\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\u003eService Temperature Range\u003c\/strong\u003e: -20 degrees F to 260 degrees F\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\u003eQuantity per Unit\u003c\/strong\u003e: 1 roll\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: 555S2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VYBOND","offers":[{"title":"Default Title","offer_id":51344095445298,"sku":"555S2","price":29.96,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552693.jpg?v=1782029128","url":"https:\/\/voomisupply.com\/products\/vybond-555s2-ul181b-fx-metallic-duct-seal-tape-2in-17mil-60yd","provider":"Voomi Supply","version":"1.0","type":"link"}
