I bought this and the one adapter fits my miter saw and orbital sander.

I bought this Cen-Tex hose to tie my domino to my dust collector. The smaller rubber fits the Festool dust outlet perfectly. Maybe you can buy them separately.
I use this - really love it. Easier if you also get the dewalt universal adapter.
