Connect a Router table fence port to a Festool D27 antistatic hose
How to join a Router table fence port to a Festool D27 antistatic hose, and what stops it leaking dust.
Not compatible without stepping down. A Festool D27 antistatic hose is far larger than the Router table fence port, so it needs a 2-1/2 in to 27 mm step reducer.

The two ends
| End A | Router table fence port (2-11/16 in OD, 2-1/2 in ID) |
|---|---|
| End B | Festool D27 antistatic hose (35 mm tip in OD, 7/8 in ID) |
| Fit type | hose cuff into female socket |
| Reducer needed | 2-1/2 in to 27 mm step reducer |
Shop notes
The hose tip is about 35 mm and the port socket about 64 mm, a gap of 28 mm, so the port socket simply swallows the hose tip with no contact. A 2-1/2 in to 27 mm step reducer is needed, and even reduced the airflow is mismatched between the Router table fence port and the Festool D27 antistatic hose.
Wrapping tape to close a 28 mm gap never seals cleanly and chokes the airflow further. Step the sizes properly, or pair each end with a fitting closer to its own size.
