Compatibility Confirmed by Bosch
The official 4100XC-10 page includes common 2-1/2 in. vacuum hoses and the VAC004 in its “Works With” list. The VAC004 page also names the 4100XC among compatible models.
| Your hose | Bosch solution | Status |
|---|---|---|
| 2-1/2" | Connection to the saw port | Listed as compatible on the 4100XC page |
| 35 mm | Bosch VAC004 | Manufacturer adapter verified |
| Other size | Adapter sized after measurement | Verify before purchase |
When to Use the Bosch VAC004
The VAC004 adapts a port sized for a 2-1/2 in. hose to a 35 mm hose. It is Bosch’s documented solution for compatible 35 mm hoses on the 4100XC. It should not be presented as universal for every tool: compatibility depends on the intended 2-1/2 in. port and 35 mm hose system.
Verify the Actual Fit
Even when Bosch lists a 2-1/2 in. hose as compatible, check the real cuff on a third-party hose. A nominal size may describe the hose rather than the mating surface. Check ID, OD, taper and insertion depth before clamping or modifying a fitting.

Technical Sources
Disconnect the saw before measuring or connecting the system. Keep all guards in place and prevent the hose from interfering with the workpiece, fence or saw movement.
