How should sections of the clothes dryer duct be fastened together?

The correct approach to fastening sections of the clothes dryer duct together is by using pop rivets or sheet metal screws that are no longer than ⅛ inch. This method is favored for a number of reasons. Firstly, it ensures a secure and durable connection that can withstand the heat and air pressure produced during dryer operation. Using pop rivets or screws prevents any potential leaks where lint could escape, which is critical for maintaining the efficiency of the dryer and reducing fire hazards.

Furthermore, this fastening method complies with industry standards and building codes, which typically dictate that metal ducts must be securely fastened in a way that does not compromise their structural integrity. Unlike duct tape or glue, which can degrade over time or fail under heat, metal fasteners provide a reliable long-term solution.

Using zip ties, while useful in certain situations, may not provide the necessary stability and security for a dryer duct connection, particularly since they are not designed to handle high temperatures. Inadequate fastening could result in disconnections or leaks that would be hazardous. Similarly, adhesives are unsuitable for this application, as they could weaken due to heat exposure and may not hold under the dynamic conditions present during the dryer's operation.

Thus, utilizing pop rivets or sheet metal screws
