Can of worms
The world of PVC plumbing pipe, dust collector pipe, HVAC pipe, and dust collector hose is a real can of worms. Between incompatible ID and OD it seems like I am forever looking for the elusive silver bullet adapter! I have had good luck with what the plumbing world calls hubless connectors. These are basically a rubber hose with a stainless steel hose clamp on both ends. There is a shielded type that also has a stainless steel cover but that limits the stretch and is to be avoided. These come in all sorts of transition sizes and shapes, including some angles, and are very stretchy for either going over large pipes or will squeeze down for smaller pipes.
Good luck, I feel your pain.
