Description
Overview:
This O‐Ring is a genuine Makita sealing component designed to maintain a tight, leak‐resistant seal within compatible power tools. Made from durable black rubber, it helps prevent lubricant seepage and blocks dust and moisture from entering critical assemblies, protecting bearings, gears, and internal electrics. It is widely used across Makita compact tools, commonly in angle grinders such as the 9553NB and 9556NB, where reliable sealing supports smooth operation and extends service life. The O‐Ring is engineered to Makita's original dimensions for correct compression in its groove, so it fits without modification during routine servicing or repairs.
