Connect a Fein 30 mm tool port to a Fein Turbo 35 mm hose
How to join a Fein 30 mm tool port to a Fein Turbo 35 mm hose, and what stops it leaking dust.
Not a direct fit. Joining the Fein 30 mm tool port to a Fein Turbo 35 mm hose needs a 30 mm to 35 mm step reducer.
Rings drawn to scale from the measured diameters in the table below.

Shop notes
Measured across the joint between the Fein 30 mm tool port and the Fein Turbo 35 mm hose, the hose (35 mm) is 5 mm larger than the port (30 mm), so the port rattles inside without gripping. A 30 mm to 35 mm step reducer closes that 5 mm step so the two hold together instead of leaking at the gap.
A 5 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.
