Vacuum adapter for Bosch PEX 220A sander. Fits a vacuum hose with tapered 31mm outside diameter. (My vacuum hose is 30mm at the end but 31.5mm after about 30mm)
Note: Inner diameter for hose connection part is 31.5mm with a length of 35mm.
I used screws to connect to the original sander dust port, as the clip solutions (even the original bosch accessories) don't really stay connected.
