Description
Overview:
This genuine Hitachi/Hikoki O‐Ring (OEM No. 876796) is a durable black rubber sealing ring for rotary hammers such as DH18DPC and DH25DAL. It sits within the tool's mechanism to create an air‐ and grease‐tight seal, helping to maintain internal pressure and keep contaminants out. By preventing leaks, it supports consistent impact energy, smooth drilling, and longer service intervals. The material is chosen for resilience under vibration and reciprocating motion found in rotary hammers. Use it as a like‐for‐like replacement during scheduled maintenance or repairs to restore factory sealing performance and protect adjacent components. Suitable for professional trades and DIY users looking to keep their Hikoki/Hitachi tools running reliably. Genuine Part, supplied to original specification for proper fit and function.
