Hon&Guan Duct Connector Flange 6 Inch, Plastic 6 Inch Dust Collection Fittings Dryer Vent Connector Flange For Heating Cooling Ventilation System, Black.

Good fitting for my laser engraver exhaust port. Does exactly what i needed it for.

For the 5" flange, the OD is 4 7/8". It worked great with the Powertec 5" flexible dust hose. The material thickness is thin but I didn't have any problems during install (I used a cabinet screw to install). The flange is narrow but just right combined with the Oneida Super Dust deputy 5" outlet installed directly above (the Dust Deputy flange being wider).

Worked well for my needs. No complaints

I decided to try to make some (feral) cat shelters out of used coolers. I bought the 4" and 5 " covers to line the entry/ exit hole. I needed a 6" too, but decided to try something else for the 6" hole. The 4" was really too small for the cats and did not end up using it. I wanted the tube to stick out to help create a bit of a rain barrier. The red Igloo cooler was so thick that the tube was almost flush with the wall, so it didn't matter which way it was installed. I installed it with the flange on the outside to cover the unsightly, rough edges of the hole. The blue Coleman cooler was thin enough to get the tube to stick out a bit. I was hoping this would be a nice tight fit, but it was pretty loose. I didn't want the ugly look of duct tape. I tried some electrical tape around the rim, but it didn't stick. Someone had recommended using calk to seal the hole, but one of the instructional videos said their cats don't like the smell of the calk and won't use the shelters. I really like that this had the screw holes, and I didn't have to worry about messy calk. Low price and screw holes were great for my project.

I bought this to use with a modular custom 6" exhaust vent duct for a portable AC unit in a dedicated, climate controlled media equipment closet, and it worked perfectly. My first portable AC unit in the closet quit working after about 5 years, so I had to replace it. Unfortunately, the new AC unit came with a different type of exhaust hose attachment, even though both units were LGs, and I stupidly built the first exhaust duct to last forever. Since I needed to recreate part of the exhaust duct because of the different AC exhaust hose attachment types, I upgraded the 6" inline exhaust fan I'd been using to help push the exhaust about 20' to an external wall, as I wasn't sure how much longer the original fan would last and they're relatively cheap. Additionally, I wanted to install a one-way butterfly baffle to prevent any cold air from coming back into the closet while the AC exhaust wasn't running, which I hadn't done before. And, because I've recently begun to fully appreciate that everything will eventually need to be replaced at some point, I wanted to make the exhaust duct as modular as possible, because connecting flexible ducts to portable AC exhaust hoses, inline fans, and one-way baffles is a time consuming nightmare. So, I added an insulated adhesive gasket between the two pieces of this duct connector, and superglued some screws onto one of the pieces, then used nuts to hold them together. This way, I won't have to tear the whole exhaust duct apart again just to replace one part of it, should something fail again (portable AC, inline fan, baffle, etc.).

A portable air conditioner needs venting to the outside for heat transfer. The window hardware that came with my unit was cheaply made and broke. So I had too use a little "redneck engineering" to make it happen. Thus flange is EXACTLY what I needed to feed the vent duct through it. Once installed, I sealed it up for a weatherproof fit. In case you're wondering, the nylon stocking I used as a bug shield expands when the A/C is running. I know it looks funny, but that's what redneck engineering is all about -- makeshift designs that work but look stupid.

It was a good product , but wrong size

A portable AC hose doesn't fit as advertised in the picture. Also, the material is very thin.

Works great love it

Buen producto, exactamente como lo especifican!.
