Description
Overview:
This O Ring is a genuine DeWalt sealing component for selected hammer drills, including the D21570K Type 1 and DWD522KS Type 1. Made from tough black rubber, it provides a tight, reliable seal to keep lubricants in and dust or moisture out, helping your tool run smoothly under load. It is designed for the vibration and impact of hammer drilling, maintaining compression where housings, shafts or connectors meet. As an OEM-quality part (OEM No. 99014-04), it fits precisely and is suitable for routine maintenance or repairs. Simple to install during a service, it restores correct sealing performance and supports the tool's hammer action and torque delivery in daily site or workshop use.
