Shop notes
Measured across the joint between the Festool 36 mm (D36) tool port and the 2-1/2 in Ridgid / Craftsman locking hose, the hose (57 mm) is 13 mm larger than the port (44 mm), so the port rattles inside without gripping. A 36 mm to 2-1/2 in step reducer closes that 13 mm step so the two hold together instead of leaking at the gap.
A 13 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.
