Connect a Portable table saw 2-1/2 in port to a Festool D32/22 antistatic hose
How to join a Portable table saw 2-1/2 in port to a Festool D32/22 antistatic hose, and what stops it leaking dust.
Not compatible without stepping down. A Festool D32/22 antistatic hose is far larger than the Portable table saw 2-1/2 in port, so it needs a 2-1/2 in to 22 mm step reducer.

The two ends
| End A | Portable table saw 2-1/2 in port (2-1/2 in OD, 64 mm OD) |
|---|---|
| End B | Festool D32/22 antistatic hose (7/8 in ID) |
| Fit type | male port into hose cuff |
| Reducer needed | 2-1/2 in to 22 mm step reducer |
Shop notes
The hose is about 22 mm and the port about 64 mm, a gap of 42 mm, so the port simply swallows the hose with no contact. A 2-1/2 in to 22 mm step reducer is needed, and even reduced the airflow is mismatched between the Portable table saw 2-1/2 in port and the Festool D32/22 antistatic hose.
Wrapping tape to close a 42 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.
