Repa Market 4'' Inch Duct Splitter to 45° Degree 4" Inch Branch for Exhaust Fan, Dryer Vent Hose - 3 Way Duct Hose Connector, Wye Shape, Ducting Adapter, 4x4x4 Splitter

The unit did as exactly as needed to plumb two separate vent lines into one vent hole.

This is a well built adapter! Super rigid doesn’t buckle or bend. I saw some complaints of odd sizing- this fit perfectly into my current standard size dryer vent. Took about 20 mins to install. My only complaint is they used a silicone sealant to seal some of the inside edges of the Y, and they missed some of the holes so air could escape. But a wrap or two of some aluminum vent tape and it sealed perfectly! Would have given 5 stars if they just hit those few small holes! Would absolutely recommend!!

Perfect part, just what I was looking for! Thank you

Muy bueno

very solid, high quality wye
