I bought the Kenmore 6 ft. Snap-Lock Flexible Pipe for my dryer. It is a nice one piece alternative to fabricating a lot of smaller pieces together. It says it takes 6 inches of pipe to complete a 90 degree turn, but I would argue it takes 9 inches. Note that a clamp is still needed to secure the pipe to the dryer, and to the wall, and that those clamps are not included.
Might have been more useful covering the Thanksgiving turkey. Trying to "stretch" this stuff and bend it to fit the opening without tearing it is almost impossible. Might work if it is to go in a straight line, so to speak. For me it was a complete waste of time and money.
Had to reconnect to dryer because it came loose and the aluminum is very thin
Serviceman installed parts
had to purchase as a kit and was not able to get my money back
