Outlet (extraction?) hole too big for my Intake fan. How to fix?

Hi, beginner here, starting ym first grow.I bought a "tester" tent for the first time - 90x90x180 cm. It has a 150mm extraction holeLogically, I also bought 150mm tubing, 150mm carbon filter and AC infinity S6, which I think also has 150mm attachment size - so all in all - everything fits pefectly.

However, I will buy a bigger tent aoon - 120x120x200 cm, but all of them have 200mm+ outlet holes.

My question - If my AC infinity is 150mm, my tubing is 150mm , carbon filter is 150mm, but the extractor hole (where I use AC Ifinity to suck the air out) is 200mm, how can I make sure there are no air leaks? How to attach the tubing and carbon filter to the bigger etractor hole? (AC infinity isnt connected to extraction hole its outside the tent, connected to tubing )

I just CANNOT find 120x120x200cm tent which has 150mm outlet.....
Thanks for advice.

I've maybe missed something but there's drawstrings on the vents/holes to tighten around the ducting for a light tight fit.

Yeah there should be two duck socks on every port and both have draw strings with a toggle on.
You just pull them reasonably tight.

I see, I didnt see any drawstrings in the tent description.
But I guess that is not a too hard of aDIY solution..
Thanks for commenting!

Thanks for your effort, I see now. Ill just ask the manufacturer about those

You should be able to seal it up with the drawstrings like others have said. There's another drawstring inside this outer one. This is an 8 inch vent with just a couple power cords going through and sealed up light tight. I'm sure any tent you buy these days is going to operate in a similar fashion.
