Intulon 6-inch Tube Portable AC Air Conditioner Ex

Expensive, but works perfectly.
This connector fit perfectly over my 6” AC vent hole. It has a sufficient number of screw holes for secure mounting. I added a bead of silicone on the backside to improve the seal on the drywall. The 6” vent tube screwed in exactly as described. No tape! Looks super professional!

Excellent idea! A little overpriced
Works great if you install it reversed like others. Had to bite the bullet and got this overpriced item because we don’t want the hose to go over the window. Minus one star for the pricing for an otherwise fantastic product.Note, the 6″ metal duct is the same diameter as the lip of the intulon tube so you can’t screw them together. However, you can tape them together by using a good-quality HVAC aluminum tape. Also, the lip of the open rock sheet wall where the screws are going into need to be reinforced. you can cut out square pieces of wood from a 5-gallon paint wood stick (available at HD, Lowe’s, etc.) and use wood glue to secure them to the inside wall as shown in the photo and it should work great.Finish it off with the KWG 6 inch round stainless steel vent cover for the external stucco wall and the result is fantastic!

Neat product that could use improvement….
Bought this to try as it really seems good for the portable air conditioners during winter time when they are in the closet and not used…. Problem is, no way to nicely connect this to the 6 inch Outdoor Exhaust Vent that goes thru the wall from the outside…. Would be nice to have it printed with an extra lip portion that overlaps and fits the commercially available Outdoor Exhaust Vent with a small groove for an o-ring seal, and also have a small groove for an o-ring seal on the screw-in cap itself…. I used it “backwards” as others did in the pictures/reviews as this not only looks much better, but also gave a tiny portion that I formed the Outdoor Exhaust Vent around on the outside with a flange tool, then used commercial aluminum HVAC sealant tape to keep air from escaping into the wall. Bought the other brand (half this price) to try on portable air conditioner number two…. We will see which one works better as it seems to have the same shortcomings as this one, though at a much reduced price point….

Worked as Designed but Had to Purchase Screws
It works as designed but I did have to buy some stainless-steel screws to make sure that they do not rust.

This wall flange connector is exceptionally well made and very durable. The plastic thickness of the insert is there because of the need for very large deep thread grooves to accommodate your 6” air conditioning hose, a really good design for giving it installation strength and durability of annual use.For those of you who have a construction knowledge, some sheet metal experience and the tools to do an installation like this, you’ll find it very easy and have it done in a few hours or less. I installed the flange in my bedroom wall so not to block my only opening window. The wall insert has an odd outer diameter for you to connect a sheet metal duct to it, 6.2”, not the standard 6” as would be expected, because of that you need to fabricate your own. I solved it by taking a 6” pre-made duct, cutting it to the length I needed with aviation snips and then cut a dozen slits along the length of the duct piece to flare them out and bend them back in to surround the outside of the plastic flange.This was pretty much the longest part of installing this flange in the wall. The use of a wall stud sensor and some knowledge of building structure helped to correctly determine where to cut the hole through the wall. The exterior square cover vent (from Amazon as well) was what I was joining to the now prepared duct to. Once installed, I sealed the insert (inside the wall space and outside on the side of the house) with weather proof clear silicone after inserting a piece of standard mesh screen to keep bugs and stuff out that may try to crawl in. For securing the inner flange, (to be inserted it into the ‘flared out’ metal duct) I devised a simple wood bracket to give the wall strength to hold the flange in place.The things you may need to make this work are coming up with a way to keep the flange secure in your drywall as 6 screws into the drywall are not going to keep the flange there year after year of use and disconnect, re-attach, etcetera. The solution was to make an 8” square piece of plywood, with a 6.25” hole cut through it to let the flange pass through it, and to get this inside your wall, I cut it in half, so there are two pieces. By pre drilling holes through the drywall where the flange’s 6 holes would be mounted let me know the plywood bracket would be, to add in drywall screws to the “square” portion of the bracket keep it firmly in place. This worked out exceptionally well and after filling the holes with drywall mud, sanding and finishing, it is now ready for a paint job and once that is complete, you will never know all the effort that went into putting this AC hose connecting wall flange in place.Before installing something like this, you should know how thick your walls are from inside to outside your home, (2×4 or 2×6 or 2×8 wall construction) and have an idea where the studs are to not cut into one when you are deciding where to place your hole. This it is a great addition to my home and very convenient to connect the portable AC unit every season. Hope this helps.
