Genuine Makita part 213073-6 — O‑Ring "9" (rubber sealing ring). Designed as a direct replacement seal for Makita rotary hammers and hammer drills, it restores the airtight/grease seal that prevents performance loss and oil/grease leakage, and it’s supplied as a single sealing ring.
This small but critical genuine Makita spare is commonly kept with other power tool parts for rotary-hammer maintenance and is simple to fit during routine service.
Example models this part is listed for models: BHR202 / DHR202, BHR241, BHR242, BHR261, HR2455, HR2450 / HR2470, HR2811F and certain DHR/DHR-series SDS‑plus rotary hammers.
Makita identifies it as "O RING 9" (commonly listed as 9 mm in parts listings), so you can match that designation when replacing the worn seal.
Quick, inexpensive, and original Makita — fits into the sealing groove to get your hammer drill working smoothly again.
