Last week I received the Mini Dust Collection Separator (#143868) from Woodcraft.

My Shop-Vac is a 1993 model and the 2 1/2" hose will not slip onto the inlet or outlet. The hoses and the fports are exactly the same size.

To rectify the problem, I used two 3" cans (cut along the length) and 4 pipe clamps to make two unions. The idea works fine and I am delighted with the Separator.
