DryerFlex Transition Duct Hoses

Choosing the Right Duct

UL2158A Logo

The dryer's transition hose can be an important factor in saving energy. It can also be a critical factor in protecting property and even lives. Why? Dryer-caused home fires have been documented at levels exceeding 14,000 a year. Flammable lint accumulates quickly in every exhaust system (even when the lint filter cleaned with every load). This can create a very real fire danger.

What's going on behind the dryer?

A big problem faced in laundry rooms is the crush point. Dryers naturally vibrate, or get pushed back against the wall. A transition hose that's not built strong (like every duct that was previously available before DryerFlex) can restrict airflow and actually increase the rate of lint accumulation.

The DryerFlex Advantage

Marking on Product
Constructed with all aluminum ribbon, DryerFlex fire-rated duct is as flexible as "slinky" foil flex yet stronger than semi-rigid aluminum, making installation easier and every laundry room safer. Quite simply, DryerFlex provides the best functionality of the old transition ducts without any of the defects. DryerFlex always maintains its four inch diameter whether fully extended or compressed. This smooth interior allows the dryer to perform at peak efficiency. It's strong aluminum ribbon protects against crushing and flamespread. Choose DryerFlex for exhaust duct that's safe, efficient and easy to install
 

Choose the Highest UL Fire Resistance Class

For safety reasons and added peace of mind, only UL2158A listed ducting, like DryerFlex, should be used to connect the dryer's exhaust system (non-listed hose such as that commonly used to vent bathroom fans should never be used). While building code and dryer manufacturers all require a UL 2158A listed transition duct, there are differences upon further testing. It is very common to find listed material that is fairly safe but does develop smoke and flame spread at lower temperatures. DryerFlex is the only flexible duct that has zero flame spread and zero smoke developed meaning it withstands fire exposure up to 482° with zero development of smoke or fire.

How DryerFlex Helps

  • Makes Connecting and Cleaning Easier
  • Helps To Protect Against Flame Spread
  • Saves Money on Power Bills
  • Lengthens Dryer Life

Important Safety Tip
Flexible white vinyl bathroom exhaust vent hose should never be used to connect a dryer. It is highly flammable, deteriorates over time from the heat, and it crushes easily.
  

Dryer Transition Hose Connection Comparison

DryerFlex® has all of the good features of foil and semi-rigid without any of the shortcomings.

Comparison Summary: Foil

Like DryerFlex, foil transition hose is pliable and easy to work with. However, building code prohibits the use of foil in an attempt to reduce the number of fires caused by dryer exhaust problems. Foil duct has a narrower, rough interior that restricts airflow and a coating that is flammable.

Comparison Summary: Semi-rigid

Semi-rigid is accepted under standard building code because it maintains its 4" diameter and has a smooth interior. It is harder to work with, crushes easily and is difficult to twist. DryerFlex is also code approved with a UL 2158A listing, but it is very workable making it easier to connect the dryer.

The DryerFlex Advantage

DryerFlex outperforms other exhaust hose because of its unique design: all metal construction using five layers of 25 micron aluminum ribbon wound over galvanized, zinc coated wire.

Strength

This approach to building a better transition duct makes DryerFlex tough enough to protect against punctures or crushing, helping prevent efficiency loss and fire dangers. In the event of a dryer fire, this design can work to hinder fire expansion into the wall with torch tests up to 482 degrees showing zero flame spread or smoke development.

Flexibility

Some of the same features that make DryerFlex tough, including the wrap of multiple ribbon layers over a spiral wire, also makes DryerFlex easy to manipulate into the right bend for every dryer connection.
