Hydrofarm Aluminum Duct Tape - 2 mil, 120 Yard Roll

Hydrofarm Aluminum Duct Tape for Sealing Ducting

This roll holds 120 yards of aluminum tape, or 360 feet. The foil is 2 mil thick and carries a pressure-sensitive adhesive on its back. Firm pressure from a hand or a squeegee sets the bond. Hydrofarm makes it as a heavy-duty, heat-resistant tape for attaching, joining and repairing ducting. The adhesive is built to hold in hot temperatures and dusty environments. That suits the warm air leaving a light hood and the dust that builds up around an exhaust fan. The roll is easy to cut, so lengths come off quickly during an install. Aluminum foil holds the shape it is pressed into, so the tape follows round collars and seams. It also leaves a bright metal finish that matches foil ducting. Hydrofarm lists it under part number ACT120. Shipping weight for a single roll is 2.86 lb.

Using Aluminum Ductwork Tape on Grow Room Air Lines

Wipe each joint clean and dry before taping, because dust and condensation weaken the bond. Slide flexible duct fully over the flange or collar first. Secure it with a clamp or zip tie, then wrap the tape over the joint. Overlap each wrap by about half the tape's width so no seam is left open. Rub the tape down hard along its full length to set the adhesive. On a carbon filter flange, a sealed joint keeps air from slipping past the carbon. A torn section of foil duct can be patched by wrapping tape over the tear. Tape also closes small gaps where a duct passes through a tent port or wall. Avoid stretching the foil as it goes on, since it can split under tension. Check taped joints at each crop change, as heat cycles and fan vibration can loosen old tape. Keep the roll in a dry place between jobs.
