Repa Market 4 Inch Flexible Aluminum Duct - 9.94 to 19.68 Inch Long – 4 Inch Duct with Galvanized Steel End Sleeves - HVAC Semi Rigid Dryer Vent Hose - Dryer Vent Tube - Dryer Vent Aluminum Duct

Pay NO attention to negative reviews, need a twisting 8” 90 degree offset to go from a hood below to exterior exhaust wall inside a a standard wall cabinet USE THIS! Quality ends and expanding flexible center made a tough job EASY worth every penny.

This flex duct works great for tight spots I install this with my 75 gallon water heater for the exhaust and made my life easy to put it in. Very flexible and it seams very durable doesn’t look like it would corrode

good quality and perfect length for what i needed. The quick tighten clamps make it perfect

I would definitely recommend people to use this rather than a cheap dryer hose wherever possible. It is much more rigid, and made of much more fire-resistant materials. So there is substantially reduced chance of burning your house down. In my case, the previous owner's dryer vent had the dryer plugged straight into it with no extra ducting, which wouldn't have been a problem except the new dryer's vent was in a different spot. Fortunately it was possible, with the point of a knife, a lot of persistence, and more than a few "encouraging words" to convince this duct to slip inside a pipe of the same diameter. So it's more versatile than expected. Seems to be holding well and isn't slipping loose.

Excellent product
