The BSC PREFERRED 99156 is an extra-strength cloth duct tape designed for sealing heating and air conditioning ducts as well as a wide range of general trade applications. The tape measures 1.87 inches wide by 60 yards long and is constructed at 10 mil thickness, delivering a durable, airtight, and waterproof bond. The silver cloth backing resists tearing and conforms to irregular duct surfaces. HVAC technicians, plumbers, and general contractors reach for this tape when a reliable, multipurpose sealing solution is needed on the job site.
This tape is suited for residential and light commercial HVAC duct sealing, pipe wrapping, patching, and general mechanical room repairs. Its waterproof adhesive and heavy cloth construction make it appropriate for both interior and exterior applications where moisture resistance matters. The roll format and standard 1.87-inch width work with most common tape dispensers found in field service kits.
Designed as a general-purpose cloth duct tape compatible with standard sheet metal, flexible duct, and rigid duct surfaces used in residential and light commercial HVAC systems.
This tape is typically applied by HVAC technicians, plumbers, and general contractors without special tools beyond a tape dispenser or utility knife. Clean and dry all surfaces before application to ensure maximum adhesion. Do not use this tape as a substitute for listed duct sealant mastic where local mechanical codes require it. Consult applicable HVAC and mechanical codes before use on pressurized duct systems.
