Adapter (35mm to 32mm) - adapter is connected to the 35mm hand tube or extension tube that comes standard with most shop vacs and allows the use of common 32mm (1 1/4") accessories. These include many dusting brushes, crevice nozzles, upholstery nozzles, pet grooming tools and select floor tools (including those with mop attachments). Many of these tools are not available in the larger 35mm wand size that normally comes with shop vacs (eg, Nilfisk, Bosch, Miele, Sebo, Stihl, Festool, Flex, etc). Owners of the Numatic/NaceCare Henry vacuums need not use this adapter...all of the 32mm accessories are direct fit to your hose end tapered tool attachment.
