NASHUA 349 Duct Tape — General-Purpose Repair
This black duct tape uses a polyethylene-coated cloth backing with a rubber adhesive for indoor and outdoor tasks. It is supplied as a continuous roll measuring 1 7/8 inches wide by 39 yards long. The construction suits assembly, manufacturing, metalworking and general maintenance jobs.
Temperature range defines the practical envelope
The tape performs between 40 degrees F and 200 degrees F, so it holds in cold storage and resists softening near heat sources. Outside that window the adhesive can lose grip or the backing may degrade. Installers should verify the service temperature before committing to critical seals.
16 mil thickness decides if the tape fits the joint
At 16 mil the tape bridges gaps and resists tearing on rough surfaces, yet it remains thin enough to conform around pipes and corners. Thicker grades add bulk for heavy abrasion; thinner grades tear more easily. Match the mil rating to the mechanical stress the repair will face.
