Attach two hoses of different diameters together. A step down in size by a reducer increases air velocity near the machine where it's needed most. Available in two sizes.

Perfect Bridge
Purchased this reducer to mate with my midi lathe along with a vacuum port attachment to the lathe. It was a perfect bridge between the 4" and 2.5" hoses.

Worked as expected
Picked up a dust collector with 4" ports at a garage sale and many of my current machines use a 2-1/2" port.
