The KUPA #520K13 dust seal cap is a precision-machined copper component designed for use in the front end of the spindle assembly of the KUPA KP-series handpieces (such as the KP-55 and KP-60). This cap helps protect the internal components — especially bearings and rotating spindle assemblies — from dust, debris and metal shavings that can impair performance or shorten tool life. The cap acts as a barrier and sealing element, preserving smooth operation and extending the service interval of your handpiece.
