The KUPA #520K15 Small Dust Seal is a precision copper seal designed for the front end of the handpiece spindle in the KUPA KP series (e.g., KP-55/KP-60). This smaller dust seal helps prevent dust, debris and metal shavings from entering the internal chamber of your handpiece, protecting bearings and other critical components. By installing this seal you can help maintain smooth rotation, reduce contamination-related wear, and extend the service life of your handpiece.
