Nashua 1086927 UL181-B Foil Duct Tape 2 in X 60 Yd Silver

Product Description

The NASHUA 1086927 is a UL181-B listed silver foil duct tape designed for sealing and joining flexible and rigid duct systems in residential and light commercial HVAC applications. Measuring 2 inches wide on a 60-yard roll, this tape meets the UL181-B standard for use on Class 1 flexible air ducts and air connectors. The pressure-sensitive adhesive bonds to metal, foil-faced duct board, and flex duct jacket, creating a durable, airtight seal. HVAC technicians and sheet metal contractors rely on UL181-B rated tape wherever code-compliant duct sealing is required.

This tape is suited for sealing longitudinal seams, spiral lock seams, and end joints on flexible ductwork and duct board assemblies. It is commonly used during new construction HVAC installations and service calls requiring duct repair or modification. The silver foil facing is compatible with exposed and concealed duct installations in both attic and conditioned-space environments.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor in accordance with SMACNA standards and applicable local mechanical codes. Clean and dry all mating surfaces before applying tape to ensure proper adhesion.
