Connect a Ryobi sander port to a Makita 38 mm hose
How to join a Ryobi sander port to a Makita 38 mm hose, and what stops it leaking dust.
Reducer required
Not a direct fit. Joining the Ryobi sander port to a Makita 38 mm hose needs a 1.42 in / 36 mm ID to 38 mm step reducer.

Shop notes
Measured across the joint between the Ryobi sander port and the Makita 38 mm hose, the hose tip (38 mm) is 2 mm larger than the port socket (36 mm), so it will not seat. A 1.42 in / 36 mm ID to 38 mm step reducer closes that 2 mm step so the two hold together instead of leaking at the gap.
A 2 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.
