Connect a 5 in dust-collector hose to a 6 in dust-collector hose
How to join a 5 in dust-collector hose to a 6 in dust-collector hose, and what stops it leaking dust.
Not a direct fit. Joining the 5 in dust-collector hose to a 6 in dust-collector hose needs a 5 in to 6 in step reducer.
Rings drawn to scale from the measured diameters in the table below.

Shop notes
Measured across the joint between the 5 in dust-collector hose and the 6 in dust-collector hose, the hose (152 mm) is 25 mm larger than the smaller hose (127 mm), so the hose rattles inside without gripping. A 5 in to 6 in step reducer closes that 25 mm step so the two hold together instead of leaking at the gap.
A 25 mm mismatch feels close enough to force, and it will hold for a minute before it works loose under airflow. Fit the step ring rather than trusting friction on a gap this size.
