Original Makita 325798-1 — O‑Ring / seal case A, a direct replacement part for Makita rotary hammers. This genuine Makita seal houses the O‑ring and internal sealing surfaces used on models such as HR2300, HR2600, HR2610 (including HR2610T) and the M8700/M8701 series, restoring the tool’s grease/oil seal and preventing leakage that can impair piston and impact performance.

Built to the same specifications as the factory component, the 325798-1 installs quickly in the hammer assembly to eliminate play, preserve lubrication, and keep the impact mechanism operating smoothly — a small, inexpensive part that protects costly internal components. Sold as one original Makita unit; compatible alternate listing numbers include 3257981.

Replace a worn or damaged seal case with this genuine Makita 325798-1 to restore reliable sealing and extend the service life of your rotary hammer.
