Been using Bosch VAC005s for multiple applications for some time now. I replaced all Bosch fittings with Festool 35 mm fittings to use the 35 mm hoses with Kapex, Workshop Vac tools, extending hose length, and generally create more suction, and never paid any attention to the Bosch fittings.
Just went out to spare parts bin & pulled what I believe is an old Bosch tool-end fitting that came from one of my VAC005 hoses. That Bosch fitting looks like it will fit my DF 500, and other tools designed for 27 mm hoses; whereas the Bosch hoses with the Festool 35 mm fittings require the HOSEADAPTOR.
Interesting! Sorry for the confusion.
