Description
Overview:
The O‐Ring (C) for Hitachi/Hikoki cordless rotary hammers is a circular sealing ring that helps keep the hammer mechanism leak‐free and working efficiently. Made from durable rubber and finished in black, this genuine part is engineered for a precise fit within the tool's sealing groove to maintain pressure and retain grease where required. It helps preserve impact energy, reduce performance loss, and protect internal components from dust ingress.
