Can You Duct Tape a Dryer Vent Hose?

A dryer vent comes in sections and must be assembled. Depending on the configuration of the vent, the distance from the dryer to the outside wall, and the kind of vent used, it is usually necessary to connect at least two or more sections of vent. Many homeowners opt to use duct tape to seal the interior or exterior joints.

Why Tape Is Used In Dryer Vents

Tape is used in assembling dryer vent sections to cover the screws and edges of dry vent hose or pipe connections that lint might snag on as it leaves the dryer.

Duct Tape Versus Aluminum Tape

Although most home owners have a roll of duct tape on hand and it seems to hold well, over time duct tape breaks down from the heat of the dryer vent and peels off. It may flake or the adhesive may become exposed, providing a wide surface which catches lint, causing a potential fire hazard. Aluminum tape is the preferred and is the best option for sealing both the inside and outside of dryer vents because of it heat resistant surface. It is smooth and less likely to snag lint. Aluminum tape is also more durable and will not crack, flake or peel when exposed to heat.
