What Type of Dryer Transition Duct Should You Use? (And Which to Avoid)

When it comes to dryer venting, not all hoses are created equal. In fact, using the wrong duct behind your dryer can lead to:

One of the most important—but most ignored—parts of your setup is the dryer transition duct, the connector between your dryer and the wall vent. Here’s how to choose the safest, most durable, and most efficient option.

✅ Best Dryer Transition Ducts to Use

1. DryerFlex® Transition Hose (Top Recommendation)

DryerFlex is the best all-around option for most homes:

Made from multiple layers of tightly wound aluminum over steel wire
Flexible like a hose, but crush-resistant like rigid metal
Smooth interior allows maximum airflow and minimal lint buildup
UL-2158A Listed and code-compliant
Easier to install in tight spaces

🔥 DryerFlex offers the best balance of safety, durability, and ease of use — it’s what many pros (including us) prefer when rigid metal isn’t feasible behind the dryer.

2. Rigid Metal Duct (Aluminum or Galvanized Steel)

Rigid metal ducting is the gold standard for dryer venting, especially when airflow and long-term safety are your top priorities.

Completely non-combustible
Perfectly smooth interior maximizes airflow and reduces lint buildup
Extremely durable — won’t crush or tear
Fully code-compliant for in-wall, attic, or long vent runs

✅ Rigid metal ducting is the best option if space allows behind the dryer. It provides unmatched airflow performance and longevity.

The only downside: It’s not flexible, so it may require elbows, and in tight spaces, it can make accessing the back of the dryer more difficult after installation..

3. Semi-Rigid Aluminum Duct

Fire-resistant and code-compliant
More flexible than rigid metal, but still prone to crimping or crushing
Interior isn’t as smooth as rigid, so more likely to collect lint over time
Can degrade if bent repeatedly or exposed to moisture

👍 Semi-rigid is a decent option, but it’s more of a compromise between flexibility and safety. Rigid metal is better long-term, and DryerFlex outperforms it in tight spaces.

❌ Dryer Ducts You Should Avoid

1. Plastic (White or Clear Vinyl)

Highly flammable
Easily crushed and traps lint
Not legal for dryer venting in most places

2. Flexible Foil Duct

Allowed only in short runs
Rips easily, crushes under pressure
Traps lint due to its ribbed surface
Often the weakest link in otherwise good dryer setups

🧰 When Should You Replace Your Dryer Duct?

Replace your transition duct if:

It’s made of foil or plastic
It’s damaged, crushed, or kinked
You’re noticing hot laundry, slow dry times, or a burning smell
You haven’t had it inspected in over a year
