Original Makita part 213536-2 — O‑Ring 27. This genuine Makita replacement is the 27 mm O‑ring used as a sealing washer in demolition-hammer assemblies; it installs into the piston/valve area to restore proper sealing and stop air or oil leaks.
Typical fit example: commonly listed for the Makita HM1111C demolition hammer (listed as O‑RING 27 for that model). Use this part when the tool shows loss of impact power or fluid/air seepage around the cylinder.
Small, low-cost part supplied singly — a quick, direct replacement to get your tool back to service. If you keep a few Makita spare parts on hand, this item is a straightforward swap for routine seal repairs and is one of the standard power tool parts used on demolition-hammer service jobs.
