Makita 213407-3 — O‑Ring (26 mm) — genuine Makita replacement seal

Description: This is the original Makita O‑ring (marked O RING 26, part no. 213407-3), a 26 mm rubber sealing ring used inside Makita hammer and rotary‑hammer assemblies. It’s a small, inexpensive part but critical—made from durable rubber to resist grease and repeated impact cycles—and it restores lost impact performance by preventing air, oil and dust leaks at internal sealing points. Buy this genuine Makita 213407-3 if you need a one‑off replacement among power tool parts to get a hammer drill back to proper operation.

Fits (example models): commonly used in a wide range of Makita tools — for example HR2470 / HR2475, HR2630, HR2230, HR2000 and BHR202 / BHR241 series hammer drills — but it also appears in other Makita models that specify an O‑ring 26. Use these examples to check your parts diagram or manual for the same part number.

Why this part: simple like‑for‑like seal replacement — replaces a worn or flattened O‑ring to stop leaks and restore correct compression and hammer action. Sold as a single piece (part no. 213407-3) so it’s ideal for a single repair job.
