Question:
Does anyone know whether the "rolled-end" of a 6" Nordfab duct can be forced onto 6" flexible hose?

I know Nordfab makes a special adapter for connecting the rolled-end to flexible hose, but in my situation I know I'll be changing things soon, gradually eliminating some 6"-pipe-to-6"-hose connections. I don't have the space/funds to buy/store needless/obsolete adapters. Anyone know it's possible to make them fit, even if it's a bit ugly?

I know that on 4" hose it's not 'officially' possible to make them fit without an adpater (though I can imagine that SOME makes of 4" hose may fit), but in my case, I'm specifically asking only about 6". Geometry dictates that as the hose diameter gets larger, the better chance it can be made to fit without and adapter.

Any opinions?
