Love my Ryobi vacuum but had trouble finding adapters for all of my Ryobi stationary and hand tools. Many of them have different port sizes. Finally solved the problem by using the rubber plumbing pipe adaptors that have the two metal bands around each end you can tighten. Some of them I had to tighten quite a bit and I cut the excess metal off of them and bend the end down so would grab or get cut. And since they are adjustable you can adjust it for a tight or loose fit. I was able to order each size I needed off of Amazon. To help out here's a list of the sizes for the different tools I have.
Stationary Tools
Ryobi Table Saw - 3 to 2 in (large dust port).
Ryobi Combo Sander - 3 to 2 in (large dust port).
Ryobi Router Table - 3 to 2 in (large dust port).
Ryobi Band Saw - 3 to 2 in (large dust port).
Ryobi Scroll Saw - 1 1/2 to 2 in (medium dust port).
Ryobi Sliding Compound Miter Saw - 1 1/2 to 2 in (medium dust port).
3rd Party Oscillating Spindle Sander - 1 1/2 to 2 in (medium dust port).
Hand Tools
Ryobi Random Orbital Sander - 1 1/4 to 2 in (small dust port).
Ryobi Belt Sander - 1 1/4 to 2 in (small dust port).
Ryobi Biscuit Joiner - 1 1/4 to 2 in (small dust port).
Note - the vacuum side of the adapters is 2 in. You tighten it down till the hose just fits inside. The tool side of the adapter goes over the dust port and tighten it down till it's snug on the dust port.
