Connect a Metabo HPT C10FCG miter saw port to a 1-1/4 in shop-vac hose
How to join a Metabo HPT C10FCG miter saw port to a 1-1/4 in shop-vac hose, and what stops it leaking dust.
Not a direct fit. Joining the Metabo HPT C10FCG miter saw port to a 1-1/4 in shop-vac hose needs a 1-1/4 in to 1-1/4 in step reducer.

| Fit type | male port into hose cuff |
| Reducer needed | 1-1/4 in to 1-1/4 in step reducer |
Shop notes
Measured across the joint between the Metabo HPT C10FCG miter saw port and the 1-1/4 in shop-vac hose, the port (35 mm) is 3 mm larger than the hose (32 mm), so it will not seat. A 1-1/4 in to 1-1/4 in step reducer closes that 3 mm step so the two hold together instead of leaking at the gap.
A 3 mm mismatch feels close enough to force, and it will hold for a minute before it works loose under airflow. Fit the step ring rather than trusting friction on a gap this size.
