I have a Nicro vent (3 3/4" OD) sticking about an inch under the cabin
overhead. So it's a 3 3/4" OD pipe, of sorts.
I have about a 3 1/2" OD flat flange that I need to fit against that 3 3/4" OD pipe.
What I'm trying to figure out is if there's a flexible arrangement for matching these up. Like a hose clamp on each end and some kind of airtight material in between, like a waterproof canvas
of some type. I guess if I had a 3 3/4" in diameter and maybe a couple of inches long I could just hose clamp the two together.
Kind of random, I know.
