Can i use powertecs 70190 y-fitting, 4 x 2-1/2" fitting with this? will the y fitting plug into this? i need to mount it to a router cabinet.

I couldnt say for sure. I know that the WEN brand clear 4 inch hose is VERY tight around this. I did not need a clamp to hold it in my application. At $6, if it didn't is is still a handy part to have around for future use IMO.

Is the inside diameter at the flange end larger than 4 inches; it appears to get wider on the outside of the fitting, does it expand on the inside too

I already have it mounted and can't tell for sure, but I think the interior is the same size all the way down.. I have inserted a 4-inch hose and it appears to be flush at both the top and bottom.

I know its not meant for this use but could it be sturdy enough to put in a subwoofer box as an aero port.

This component is "hard plastic" but definitely appears to have a lot of strength (and the specs, that I don't have in front of me, identify a certain "weight" loading that they can withstand). I am using them for supporting wood railing in my corral for my horses, and they are holding up 50-100 pound log rails. I don't know how much your subwoofer weighs or what an "aero port" is, but if the subwoofer weighs less than 50 pounds, this will work just fine.

will 4" drain pip[e connect to this snugly enough to use on a rain water catchment system. The flange mounting on the lid of the tank?

Do not know what inside diameter is of 4" drain pipe. This is designed for 4" dust collection hoses.
