2-1/2'' Rubber Union for Dust Collection w/Pair of Clamps - Hose Coupler Eliminate Flimsy Duct Tape Connections - Dust Collector Flexible Rubber Makes Airtight Seal - Hose Clamp & Hanger

Worked well for attaching a 2.5" Magport to my SawStop router table fence.

This fit exactly as I needed.

The flexibility of this union is invaluable! My only complaint is that it comes in only two sizes. Seems like a pretty simple concept: piece of rubber and a couple clamps. Why can't Dust Right make several other sizes, such as 1-1/2", 3-1/2", 4-1/2", 5"?

works as designed.

This part is neat and works well in a dust collection system.

I use these to connect my shop air vacuum system. They seal tight and don’t use up any extra room
