HVAC Duct Sealing Tape

Duck Brand HVAC Duct Sealing Tape is a heavy-duty tape designed for sealing both rigid and flexible ductwork. It provides a waterproof bond suitable for indoor or outdoor use on cold and hot air ducts. The silver metalized tape meets the needs of professional contractors and homeowners alike.

Synthetic Rubber Blend Adhesive

The adhesive uses a synthetic rubber blend that bonds reliably to flexible and rigid materials. This formulation supports a waterproof seal across varying temperatures. The three-inch diameter core allows for standard dispenser compatibility during application.

Standard Duct Tape Constraints

As a duct tape product, it is not intended for structural repairs or permanent load-bearing joints. The tape may not adhere well to excessively dusty, oily, or wet surfaces without preparation. It does not replace mechanical fasteners or code-required sealing methods for critical HVAC installations.

Questions about this item

Will the synthetic rubber adhesive on this Duck 673753 tape need reapplication as it ages?

The synthetic rubber blend adhesive is designed for long-term bonding on both rigid and flexible ductwork; replacement is only required if the tape is physically damaged or the seal is broken.

What length of the 1.88 in wide roll runs out first during a large duct-sealing job?

The roll provides 120 yards of tape, so the linear length is the limiting factor on big projects.

Does the metalized silver surface stay cool when hot air ducts run all day?

The tape is rated for both hot and cold air ducts and the metalized surface reflects radiant heat, keeping the adhesive stable during continuous operation.
