Description
Overview:
The O Ring 31.5 is a genuine Makita sealing component for heavy‐duty demolition hammers. Made from a tough elastomer compound, it provides a tight, reliable seal inside the hammer mechanism to contain lubricant, maintain internal pressure, and keep debris out. This supports consistent striking performance and reduces internal wear. The ring follows the factory specification (nominal 31.5 mm) for a precise fit, making replacement straightforward during routine servicing or repairs. Designed for selected Makita breakers, including the HM1203C and HM1213C, it suits on‐site work and workshop maintenance. Genuine Makita Part Number 213499-2 ensures correct compatibility and dependable performance with the intended tools.
