213534-6 supersedes older part numbers: 213515-0
Original Makita replacement O‑ring, part number 213534‑6 — a nominal 36 mm sealing ring used in Makita rotary‑hammer assemblies. It’s the factory spec O‑ring that seals the piston/barrel area to keep grease and dust out and preserve hammer action, so it’s a simple, low‑cost fix that restores proper sealing and prolongs tool life.
Fits several Makita rotary‑hammer models in the HR45xx / HR52xx family — examples include HR4510C and HR4511C as well as HR5210C / HR5211C (confirm the part diagram for your exact tool before installation). This part is also listed as a replacement for earlier Makita reference 213687‑1 on some parts lists.
