Connect a Skilsaw SPT99T table saw port to a Festool D32/22 antistatic hose
How to join a Skilsaw SPT99T table saw 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 Skilsaw SPT99T table saw port, so it needs a 2-1/4 in to 22 mm step reducer.

Shop notes
The hose tip is about 22 mm and the port socket about 57 mm, a gap of 35 mm, so the port socket simply swallows the hose tip with no contact. A 2-1/4 in to 22 mm step reducer is needed, and even reduced the airflow is mismatched between the Skilsaw SPT99T table saw port and the Festool D32/22 antistatic hose.
Wrapping tape to close a 35 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.
