90 Degree Long Turn Dryer Elbow - Overcomes Length of Run Issues and Increases Efficiency - 4"
has a longer radius and smooth interior that reduces friction. It can be measured the same as straight pipe, eliminating the run-length reduction currently required for other elbows in most building codes. We estimate it pays for itself in 2 years - energy wise. UL studies show it is 500% more efficient than the standard 4" ell.

Low resistance Elbow
Very low resistance for an elbow and easy to clean but be sure to wear heavy gloves when assembling as the edges are quite sharp.
from Winnipeg MB Canada.
good product for the price
Works as designed. The two halves of the pipe still have a bit of a gap between them even after screwing together. I'll have to use some duct seem sealer or the like. Only other option would be welded pipe which is really expensive.

Helped me meet code!
This is a great product. My wife and I are currently building a new home (building it ourselves) and the laundry room is on an interior wall. Only when we started to run the dryer vent did we discover the difficulty in meeting the 35' length limit, especially after subtracting 5' for every (we had 3) 90 degree elbow. The solution: use the long turn ell to replace the 90 degree celing elbow combined with the dryer box to eliminate the elbow at dryer. The combination allowed us to reroute the vent so no additional elbows were required and straight shot out the rear gable. Great solution for tricky situation.
from Yorktown, VA.
Works if you have the Space
Yes, the flanges can be a problem. This can be remedied with screws and foil tape. Otherwise, if you have the space to use this elbow, it will improve dryer performance.
I replaced my 4 regular 90* with 3 long turn ells and kept a regular 90* on the dryer and it cut the dry time in half!
