Makita 213606-7 Spare Part - O RING 48 HM1110/1110/1HR2510

Original Makita O‑Ring 48 — part number 213606-7 — a replacement rubber seal used to restore leak- and pressure-tight sealing in Makita demolition/rotary hammers and related housings.

Dimensions: listed as O‑Ring 48 (approx. 48 mm outer diameter, ~45 mm inner diameter; thin rubber cross‑section), lightweight (a few grams) and made to the same shape and hardness used in Makita assemblies.

Where it goes: this ring fits into the crank/cylinder sealing grooves on several Makita hammer and demolition models to keep lubricant and air sealed and to prevent dust/water ingress around moving parts.

Example compatible models (as listed in Makita parts breakdowns and parts catalogs): HM0810 / HM0810T, HM1100C / HM1101C, HM1111C (HM1110/1111 series), HM1130, HR2510 / HR2511, HR3850 variants and a number of related HK/DH/DTD series tools — check the model list before fitting.

Sold individually and sized to drop into the original groove so you can quickly get the tool back into service — a small part that saves a full assembly replacement. If you keep a handful in a maintenance kit they’re handy to have among other parts for power tools.
