3M™ Vacuum Hose Adapters come in a variety of sizes to fit different sanding tools and vacuum hoses. The various adapters attach a vacuum hose to a 3M™ Orbital or Random Orbital Sander, enable different-sized hoses to fit securely together, or connect with a 3M™ Clean Sanding Filter Bag. This tight-fitting system enables maximum evacuation of dust, debris and particulate generated when sanding.
