I created this adapter to bridge the gap between a Kärcher Vacuum Cleaner and a Bosch multi-sander. It’s crafted with an intentional tight fit on both ends, so remember to add a bit of grease before attaching the adapter for easier installation.
The Bosch multi-sander nozzle boasts a diameter of 29-30.5mm with a length of 14.5mm, while the Kärcher vac nozzle features a front diameter of 34.9-36mm and is about 48mm on the clip side.
