Shop notes

The port measures about 38 mm and the hose about 38 mm, the same, so the port seats inside the hose as a friction fit. No reducer is needed for this pairing, so the DeWalt DWE7491RS blade-guard port and the Festool D36 antistatic hose connect directly.

It is a push fit, not a lock. Seat it fully and check it has not crept loose after a few minutes of vibration before you trust it on fine dust.
