Purpose-built tape for HVAC professionals

Nashua 398 is a general-purpose duct tape designed for assembly, manufacturing, construction and metalworking tasks. The rubber adhesive bonds to metal ductwork and polyethylene-coated cloth backing. It suits indoor and outdoor maintenance jobs where a continuous roll is required. Buyers who need a specialised foil or UL-listed tape for code compliance should look elsewhere.

Check surface and temperature range

The tape performs between 40 and 200 degrees Fahrenheit, so verify your duct environment stays within this window. Ensure the metal is clean, dry and free of oil before application for proper adhesion. The 72 mm width covers standard seams, but confirm the roll length meets your project scope. No liner is mentioned, so the adhesive is exposed on the roll.

Thermal limits and handling

Operating above 200 degrees Fahrenheit risks adhesive failure and backing degradation. Below 40 degrees Fahrenheit the rubber adhesive may not wet the surface adequately. The 11 mil thickness provides tear resistance during installation without adding bulk. Power draw and noise are not applicable to this passive sealing product.
