1 Set White Dual Size Wall Mount Connector for Portable Ac Vent Ac Exhaust Hose Coupler for 6 and 6.5 Inches Hose Accessories Plug

We had what seems to be a fairly unique problem - we wanted a portable aircon unit, but our living room had no windows or outside doors to put the exit vent through. However, we did have a cat flap left by the previous owners installed under a low cupboard in the outside wall. After a lot of searching, this cover fit our needs perfectly: all through summer the pipe can be screwed into it, and in winter we simply unscrew the pipe and put the cover back on. Super easy to install, and very happy that it came with screwcaps too.

EXPENSIVE but does the job ,I took down a extractor fan and screwed this over the 4” hole then screwed in the 6”ducting into it to extract air from portable air con.bit ugly on the wall but it’s the best thing I could find to vent the air

I bought this to connect to the vent hose on my portable ac unit after drilling a vent hole through the wall. Very solid and works perfectly.

Great for portable a/c units takes about 9 days for delivery

Pitch circle of screw fixing holes is inside of the cut out diameter so screws are useless. Now have to cut a ply backing plate with a smaller diameter hole to fix the screws into then fix that to the wall. Poor design.

We have a Toshiba RAC-PD1211CRU portable air conditioner and thie worked really nicely to attach the hose to a hole in the wall without any leakage - it seals to the hose much better than the ac unit itself does! This is due to the nice adhesive backed rubber gasket seals included. It's a pretty nicely thought out design. Just too bad it didn't come with any instructions - I could see some people struggling.

The mounting holes seemed just too close to the edge of the 6 inch hole cut in the drywall to securely install drywall anchors and mount this piece directly to the wall. So, I bought a square white plastic flanged wall vent connector that had mounting holes far enough away in the four corners and drilled/screwed this AC hose hose connector unit to the back/flat side of that extra part, which also then provided a neck to insert into the hole through the drywall to connect the actual vent pipe to. Seems like projects like this nearly always require an extra modification or two but this one turned out well for me in the end and the 6" portable AC hose threaded in as it should and I like having the threaded cap to close if off during the winter. Just my own opinions and experience here, yours may differ. Good luck!

Fits pretty good and love that it's white.

I installed these on a Lexan sheet to connect my portable A/C unit’s exhaust hose. I put a piece of aluminum screen in between it to keep critters out.

Not flexible rotationally. Twists sideways ok, but no give on rotation.
