Connect a Bosch GTS 10 table saw port to a Festool D36 antistatic hose

How to join a Bosch GTS 10 table saw port to a Festool D36 antistatic hose, and what stops it leaking dust.

Reducer required

Not a direct fit. Joining the Bosch GTS 10 table saw port to a Festool D36 antistatic hose needs a 63 mm to 36 mm step reducer.

Shop notes

Measured across the joint between the Bosch GTS 10 table saw port and the Festool D36 antistatic hose, the port (63 mm) is 25 mm larger than the hose (38 mm), so it will not seat. A 63 mm to 36 mm 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.
