I’m not sure I understand your question. You’d just plug the shop vac hose to the port on the band saw. The port is almost certainly 2.5”, so you’ll want to get a shop vac with a 2.5” hose.

It’s likely that you are going to need a reducer or expander of some sort.

My cheeseball Ryobi bandsaw has a 2.5 inch port that my shop vac wouldn’t fit into. Neither does my 4 inch dust collector hose.

With my shop vac hose, I just wrapped the nozzle with electrical tape for a friction fit. With my dust collector, I have a 4 inch to 2.5 inch reducer I picked up at Woodcraft.

I have used rubber plumbing reducers and PVC pipe off the plumbing isle from the big box store. Now most everything in my shop is using dust right connectors from Rockler. They come in both 2.5” and 4”. I am running both a shop vac for miter saw and plunge router work. 4” dust collector for every thing else. Dust right stuff makes it all very interchangeable.
