Description
Overview:
This Genuine Makita O Ring 17.5 is a small but critical sealing component used in the hammer mechanism of Makita rotary hammers and combi hammers. Made from durable rubber, it is designed to maintain an airtight and grease-tight seal under repeated impact and vibration, helping to preserve compression, retain lubricant, and sustain consistent striking performance. It is suitable for a wide range of Makita models, including the BHR242 and BHR243, and supports reliable operation during heavy site work and regular DIY use. Correct sealing reduces leaks and power loss, extends service intervals, and protects internal parts from premature wear. Manufacturer Part Number (MPN): 213258-4. This part helps restore tool efficiency when servicing or rebuilding the hammer assembly.
