It combines a reinforced backing with a high-tack adhesive layer to create an airtight, moisture-resistant seal. The tape measures 17 mil total thickness, with published adhesion near 60 oz\/in to steel and an operating temperature range of -20 degrees F to 260 degrees F. Each roll is 2 inches wide and 60 yards long. HVAC technicians use this tape for code-compliant sealing of flex duct connections, collars, and seams in residential and light commercial duct systems.\u003c\/p\u003e\n\u003cp\u003eThis tape is designed for flexible duct applications where UL181B-FX listing is required by mechanical code. Typical install scenarios include sealing flex duct to metal collars, boots, and plenums, as well as repairing tears or seams in existing flex duct runs. The high-tack mastic adhesive layer bonds under a range of field conditions, and the reinforced backing resists tearing during application. One roll is included per unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUL181B-FX listed for code-compliant flexible duct sealing and repair\u003c\/li\u003e\n  \u003cli\u003e17 mil total thickness with reinforced backing for tear resistance\u003c\/li\u003e\n  \u003cli\u003eMastic adhesive layer with published adhesion near 60 oz\/in to steel\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -20 degrees F to 260 degrees F\u003c\/li\u003e\n  \u003cli\u003eMoisture-resistant construction for airtight duct seals\u003c\/li\u003e\n  \u003cli\u003e2 inch width, 60 yard roll length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a UL181B-FX listed tape for use on flexible duct systems, suitable for sealing flex duct connections, collars, and seams where code-compliant closure tape is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians following applicable mechanical code requirements, including the International Mechanical Code (IMC) and SMACNA guidelines. Power down the air handling system before applying tape to duct connections. Surfaces should be clean, dry, and free of dust or debris before tape application to ensure full adhesive contact.
