Professional HVAC Tape

The NASHUA 398 is a polyethylene coated cloth duct tape built for HVAC professionals and maintenance crews who need reliable sealing on ductwork and equipment. Its rubber adhesive bonds to metal and flex duct in indoor and outdoor settings.

60 yard roll with 11 mil thickness

The continuous roll delivers 60 yards of 1-1/2 inch wide tape, giving enough length for long seams and multiple jobs. The 11 mil backing resists tearing during installation and holds shape on curved surfaces. Performance drops outside the 40 to 200 degrees F range.

Temperature rated for demanding environments

Rated from 40 to 200 degrees F, the tape maintains adhesion through seasonal swings and equipment heat cycles. The polyethylene coating sheds moisture and resists UV exposure on outdoor runs. Rubber adhesive stays flexible without bleeding in normal service temperatures.

Questions about this item

Will the 11 mil polyethylene coated cloth backing hold up on the 200 °F supply plenum I’m sealing?

The tape is rated for continuous service up to 200 °F, so it will stay bonded on a hot supply plenum.

How can I confirm the rubber adhesive has cured properly after I apply it?

Press the tape firmly; a uniform bond with no lifted edges or oozing adhesive shows it is set.

Does the 60-yard roll include a dispenser or do I need a separate cutter?

The roll is supplied as a continuous 60-yard length only; a dispenser or cutter is not included.
