Asked by: Pankaj
This is a 30 gauge elbow, it will depend on the situation. Typically you want to use the same "category" of pipe during installation. If you have any other inquiries about our Master Flow products please call Technical Services at 800-211-9612.

One of them I set the angle them compressed it so it would fit in the wall. Worked out great. These are much more durable than the aluminum ones.

Rated 1 out of 5 by from Pulls Apart Easily and It Leaks Air I recently purchased the Everbilt Dryer Duct Kit from Home Depot. that came with two of these kinds of elbows. It is a segmented device that you twist to get the angle the way you want. Those segments pull apart with just a little pull. Also, hot air leaks out between the segments reducing the airflow inside the venting tube reducing the power of the exhaust and also the distance you will be able to push the air and lent. The distance the hot air has to travel in my setup is about six feet vertically then out through the basement wall. You probably will have to apply tape around the leaks and the segments to keep it all together, but that might create a problem later on when you want to inspect the vent for lent build up. Lastly, my kit might have been tampered with at the store because one of the clamps to attach the elbows was new and the other was old and too small. A nuisance.
