Duct tape fixes all.

The real secret is the aluminum HVAC tape. It's like duct tape, but actually good 😆

Duct first, but then a good layer of electrical to seal everything up.

If you can find something that does 1.5" pipe to 2" vacuum hose, just find another 2" to 2.5" converter then?

You might be able to use the 1 1/2" to 2" connected to a 2" x 2 1/2".

I have used a “fernco” rubber 1.5 to 2.0 Rubber will stretch to accommodate- That 2” vacuum hose end is pretty thin so the “pipe sizing” for ID isn’t true.

The 2 inch schedule 20 pvc used for central vacuum fits the 2 1/2 inch vacuum hose perfectly. From there the 1 1/2 scheduled 40 pvc should almost fit inside the central vacuum schedule 20 pvc. Depending on your application you can use hot glue or tape if the fit is not perfect. You can find schedule 20 at vacuum specialty stores.

I had some pieces lying around and I was able to verify the 1 1/2 inch pvc fits perfectly inside the 2 inch schedule 20 pvc.
But if the fit only has to be temporary I would just use hot glue between the 1 1/2 and the vacuum hose.

Do you have hole saws? I'd be inclined to make a bushing out of a piece of 1x4. As long as there are no leaks it will work fine.

Just tape it, it's not permanent.

I've used an adjustable bit in my drill press and wood for a lot of adapters.

All I’m seeing is 1 1/2 to 2
…Do they have a 2” to 2 1/2”? Just use two adapters?

To connect a 1 1/2" PVC pipe to a 2 1/2" vacuum hose, you would need a reducer bushing with a 1 1/2" slip (glue) fitting on one end and a 2 1/2" threaded or barbed fitting on the other end. Here are some possible options:
1 1/2" PVC Slip x 2 1/2" Hose Barb Reducer Bushing 1 1/2" PVC Male Adapter x 2 1/2" Hose Barb 1 1/2" PVC Threaded Male Adapter x 2 1/2" Hose Barb
Make sure to select the type of fitting that matches the configuration of your vacuum hose (threaded or barbed). You may also need some PVC cement and/or hose clamps to secure the connections

pop can and a pair of scissors followed by some tape to seal.

What's the purpose and does it have to look good?
If it's a medium-light duty task or temporary, pack out the pipe with EPDM or something similar until it's snug with the inside of the hose, sleeve the two together and throw a clamp on it

What type of vacuum hose is it? Shop vac? Is it really a 2-1/2" hose or is that just the fitting that connects to the vacuum? I use 1-7/8" hoses with ends that fit my 2-1/2" shop vac inlets. The part that fits into shopvac accessories fits into a 2" Fernco and a 1-1/2" PVC pipe should fit into the end of a 1-1/2" Fernco fitting.
So, I use a 2" to 1-1/2" Fernco coupler to attach my 2-1/2" shop vac inlet via a 1-7/8" hose to a 1-1/2" PVC pipe.
Making a cyclone dust collector?

Once you have a 3d printer and some basic know how with 3d design software like Fusion360 hobby (free), all of these little problems just go away.

Who the fuck uses a 2,5 inch vaccum hose? Whats this for? But your answer is in the comments already, a 1,5 to 2 converter followed by a 2 to 2,5 converter.

I do. Both of my shop vacs have a 2-1/2" inlet and 1-7/8" hoses with a connector that fits the 2-1/2" vacuum inlet.
So it really depends upon where OP is getting his/her measurements from. I use a 2" to 1-1/2" Fernco coupler to attach my shopvac hose to 1-1/2" PVC.

Keep in mind that 1-1/2 PVC has an ID (inside diameter) of slightly greater than that dimension (it's ID is 1.59"), and OD (outside diameter) of 1.90".
Vacuum hose diameters vary quite a bit. Your best bet is to go to your local hardware and try different PVC couplings with a sample of your PVC and vacuum hose. You might have to use 2 couplings.
