Description
Overview:
The O-Ring 27 is a genuine Makita sealing ring for the HR4511C Rotary Demolition Hammer (part no. 213981-1). Made from durable black rubber, it provides a tight seal within the hammer's mechanism to prevent air and grease leaks, helping the tool maintain consistent impact performance and efficiency. As a precision-fit consumable, it supports the internal piston and striker assemblies by keeping lubrication where it's needed and keeping contaminants out. This reduces wear on moving parts and helps extend service intervals. Designed specifically for the Makita HR4511C, it is suitable for professional site use as well as workshop maintenance, and is a straightforward replacement during scheduled servicing or when symptoms of leakage, power loss, or excessive vibration are observed.
