Hicarer Round Ducting Take Off Collar Galvanized Steel Metal Pipe Reducer Air Duct Adapter Connector for Grow Tent Bathroom Kitchen Ventilation Systems(2 Pcs,4 Inch)

My dryer vent going through my floor into my crawls space. This was exactly what I needed. Works perfectly and is nice and sturdy. This allowed me to make a solid duct from the floor to the outside vent.Having the flange makes it really easy to connect and disconnect the drier without messing up the ducting.It will probably last another 30 years or more.

This is perfect for a dryer. It will sit flush against, with male end outwards esp side vent. also great for walls either way, i needed to go through the wall, and connect on another side and perfect length for that

4" duct with flange is heavy duty and well made and packed very well in box for shipping !!!!! Bought 2 put the flanges together sealed with permatex red high temp sealant. Used it as a dryer vent that goes thru wall to outside. You can secure the flanges to the wall your going thru. And always use High Temp Caulking around duct to seal it from outside.Would of gave it 5 stars but a bit pricey!Would definitely buy again if not so pricey!!!!

I got a portable a/c unit and it came with a window vent kit that I feel is pretty janky at best. I was willing to sacrifice a couple of holes in my door if I could do it cleanly. That's where these ducts come in. They are sturdy and large, although I could have used something a little bigger because the hoses on the a/c unit are almost 6". I will drill 4" holes in my door and mount these ducts and then slip the vent pipes over them. I will insulate the difference/gap with 1" foam weatherstrip and I even found some 4" louvers on Amazon vine to cap the holes to the outside.

I built a pump house out of pallets and slab wood and needed a vent for my generator exhaust. This 2 piece vent is very handy as I can put it just about anywhere I want.

Could have more screw holes to fully seal, used sealant, worked well
