Shop notes
A Festool D36 hose end is about 44 mm OD and a 2-1/2 in shop-vac hose cuff is about 2-1/4 in (57 mm) ID, so the D36 tip drops loosely inside without gripping. A 36 mm to 2-1/2 in reducer or a wrap-free stepped cuff makes the join hold.
The D36 tip rattling inside a 2-1/2 in cuff feels connected but leaks around the gap. Close it with a proper step, not by cranking a hose clamp onto round plastic.
