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.
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.
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.
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.
Using duct tape on a dryer vent is not recommended. While it may seem like a quick fix, duct tape can degrade over time due to heat and moisture, leading to potential leaks and reduced efficiency.
A: The tape is flammable and burns very well so I would not recommend it.
DO NOT terminate dryer vents in crawl spaces or attics. Dryer vents that terminate in crawl spaces or attics allow for moisture to deposit and encourage mold growth and health hazards.
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.
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.
Duct joints shall be installed so that the male end of the duct points in the direction of the airflow. Joints should be secured with metal tape (not duct tape).
Yes, this Nashua FlexFix tape is suitable for a Dryer Vent application. Good luck with your project.
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.
Secure Vent Hose with Clamps
If your vent hose repeatedly disconnects, it's likely due to loose vent clamps. Use clamps to tightly secure the vent hose to both the dryer and the vent opening. Ensure a snug fit to minimize the chances of the hose coming off.

The maximum length of the exhaust duct does not include the transition duct. This means that vents should also be as straight as possible and cannot be longer than 35 feet. Any 90-degree turns in the vent reduce this 35-foot number by 5 feet, since these turns restrict airflow.
Fire Hazards: Running a traditional dryer without a vent leads to dangerous lint buildup, increasing the risk of fires. Moisture Damage: Without proper ventilation, trapped humidity can encourage mold and mildew growth, affecting indoor air quality and structural integrity.
But rest assured, if you have a lint free and mostly clean aluminum or vinyl dryer vent tube and duct, this tape can aid in getting a tight seal. But to be safe and secure, you must also use any and all recommended clamps to assure duct integrity.
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.
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.
A damaged or poorly maintained dryer vent can lead to potential fire hazards, increased energy consumption, and reduced drying performance.
