Connect a Bosch GTS 10 table saw port to a Fein Turbo 35 mm hose
How to join a Bosch GTS 10 table saw port to a Fein Turbo 35 mm hose, and what stops it leaking dust.
Not compatible without stepping down. A Fein Turbo 35 mm hose is far larger than the Bosch GTS 10 table saw port, so it needs a 63 mm to 35 mm step reducer.
Rings drawn to scale from the measured diameters in the table below.
The two ends
| End A | Bosch GTS 10 table saw port (2-1/2 in OD, 63 mm OD) |
|---|---|
| End B | Fein Turbo 35 mm hose (1-3/8 in ID) |
| Fit type | male port into hose cuff |
| Reducer needed | 63 mm to 35 mm step reducer |
Shop notes
The hose is about 35 mm and the port about 63 mm, a gap of 28 mm, so the port simply swallows the hose with no contact. A 63 mm to 35 mm step reducer is needed, and even reduced the airflow is mismatched between the Bosch GTS 10 table saw port and the Fein Turbo 35 mm 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.
