Shop notes
Measured across the joint between the Oneida Dust Deputy 2-1/2 in inlet and the Karcher NT 35 mm hose, the port socket (57 mm) is 22 mm larger than the hose tip (35 mm), so the hose tip rattles inside without gripping. A 2-1/2 in to 35 mm step reducer closes that 22 mm step so the two hold together instead of leaking at the gap.
A 22 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.
