Intertape 78750 Silver Duct Tape 9 Mil 3 Inches AC20

Product Description

The INTERTAPE 78750 is a silver polyethylene foam duct tape from the AC20 series, engineered for demanding sealing, bundling, and wrapping applications in HVAC, construction, and mechanical trades. At 9 mil thick and 3 inches wide, it delivers an 18 lb/in tensile strength with a rubber adhesive backing that holds on a range of substrates. The polyethylene foam construction resists moisture and conforms to irregular surfaces. Rolls weigh 2.12 pounds and are sold individually. This tape meets several recognized building and fire codes, making it appropriate for regulated installations.

The 78750 is suited for residential and light commercial applications where a durable, code-compliant duct tape is required. Typical uses include box closing, bundling, sealing, seaming, and wrapping in HVAC ductwork, insulation, and general mechanical work. It performs within a temperature range of 32 degrees F to 160 degrees F, making it reliable across most interior mechanical environments. HVAC technicians, insulation contractors, and sheet metal mechanics are the primary installers of this product.
