Do not use duct tape to seal a hole in your dryer vent or connect it to the wall or for any other reason. Duct tape should also not be used on your air ducts. Duct tape is a common household item but poses a serious threat to the safety and health of your home when used on dryer vents.
Think duct tape fixes everything? Think again! 🚫🔧 When it comes to your dryer vent, using duct tape is a no-go. Why? It's not designed to withstand the high temperatures and can actually cause more harm than good, leading to potential hazards. Let's stick to professional solutions for a safer, more efficient ho.
Foil tape is known for its excellent insulation properties. Since it is made of aluminum, it prevents heat or cold air from escaping a system, which makes it an excellent accessory for both duct cleaning and dryer vent cleaning.
Dryer vents should be sealed with foil tape as they can withstand the high temperatures encountered during machine use. Other tapes, even duct tape, are susceptible to failure under the extreme heat. Non-foil tape can also catch on fire.
You'll want to decide between vent clamps or foil tape to secure the dryer venting to the dryer exhaust outlet and wall vent. If you're using a vent clamp to secure venting, place the vent clamp loosely on the edge of the vent hose and slide the edge of the vent hose over the wall outlet.
The flexible nature and expandable configuration allow most installs to occur without any modification to the duct or the wall penetration. A pair of jumbo zip ties and you're good to go…at least for a few months until all of the internal bumps and ridges begin to clog with lint.
Step 4: Patching a foil-type vent hose
If you are repairing a foil-type vent hose, you can use aluminum tape to patch the hole.
Dear Pat It is very important to install a tight-sealing dryer vent cover for several reasons. The dryer vent duct is a direct open path from indoors to outdoors. If the vent cover does not seal well, it is just like leaving a window partially open.
A: The tape is flammable and burns very well so I would not recommend it.
Duct Tape Can Be a Fire Hazard
While the polyethylene top layer and the bottom adhesive layer are not flammable, the mesh fabric in the middle layer is. If something happens to wear away either outer layer, you are left with an exposed middle layer—the flammable material.
While it may seem convenient to use duct tape for a quick fix, it is not safe for dryer vent applications due to its flammability and lack of heat resistance. Opting for metal tape, HVAC aluminum foil tape, or mastic sealant will provide a safer and more effective solution for sealing and repairing dryer vents.

The exhaust duct should be rigid metal 4 inches in diameter and no more than 35 feet in length or as specified by the duct manufacturer. This length should be decreased by 2.5 feet for every 45-degree bend the duct makes and 5 feet for every 90-degree bend the duct makes.
Can duct tape be used in cold and hot environments? Duct tape is heat resistant and is safe for use in temperatures up to 200 degrees Fahrenheit, but the adhesive will not hold well to extremely hot surfaces. It will eventually soften and melt due to the fabric and rubber material.
Loctite Extreme Glue is a super versatile adhesive that is perfect for sealing dryer vent pipe leaks. The high-viscosity and permanent flexibility make it resistant to vibration, moisture, heat, and UV light.
If it's permanent, just remove the pipe and patch the wall/siding using appropriate materials. If it's temporary, you can buy a little bundle of fiberglass insulation. I'd stuff that into the pipe and then use some UL181 tape to tape up the end and/or tape closed the louvers.
If your dryer vent is blocked, all of this built-up lint can become a fire hazard. The heat from your dryer could cause the lint to combust, potentially catching your dryer and parts of your home on fire.
Joints should be secured with metal tape (not duct tape). Do not use rivets or screws in the joints or anywhere else in the duct as these will encourage lint collection.
Cover the hole with an oversized square of siding material screwed in place on all 4 corners, or cut out a circle of siding material slightly smaller than the hole , screw it in place with counter-sink screws at a 45-degree going into the adjacent siding, caulk the gap & screw holes, prime & paint with matching color.
Foil duct is held in place with dryer clamps or large hose clamps. Metal tape can also be used to secure the flexible aluminum duct, too, but clamps make it easier to remove the tubing for cleaning.
Seal any duct joints using foil duct tape. Insulate the duct in areas without climate control. This will keep the moist air from condensing and minimize lint build-up within the pipe. Never use flexible vinyl ductwork to vent a clothes dryer as these pose a serious fire hazard.
Different materials used to manufacture zip ties have various temperature tolerance levels: Nylon 6.6: This is the most common material for zip ties. It generally has a temperature range of -40°F (-40°C) to 185°F (85°C). However, it can get brittle at lower temperatures.
