Makita O RING 26/6960DZ OIL UNIT COMP - 213432-4

Original Makita part 213432-4 — O‑Ring 26 — a rubber piston/seal O‑ring used in Makita demolition hammers and related pneumatic assemblies.

Nominal size: 26 mm (marked "O RING 26"), made as a round-section sealing ring to restore piston and pressure-chamber sealing.

Example fitment: commonly listed for Makita demolition-hammer models such as HM0860C, HM0870C and  HM0871C 

Sold as a single replacement rubber seal, this original Makita O‑ring is ideal when you need a direct-fit part to repair a leaking or worn piston seal — a small stock item that addresses common hammer seal failures and keeps your tool running like new. (Includes genuine Makita markings where indicated.)

Note: if you need exact placement in your tool’s parts diagram, check the HM‑series breakdown to confirm the O‑ring location before installation.
