Genuine Makita 213022-3 — O‑Ring (O RING 3). A small black rubber sealing ring used in Makita tool assemblies where a tight, flexible seal is required (fuel/air or dust sealing points). It’s listed by Makita as “O RING 3” (part no. 213022-3) and commonly sold as a single replacement piece for service and repairs.
Why this part matters: the 213022-3 is a soft rubber O‑ring engineered to maintain pressure- and dust-tight connections inside housings, carburettors and dust/nozzle interfaces. Replacing a worn or flattened O‑ring restores proper sealing and prevents leaks, poor performance or dirt ingress that can lead to bigger repairs. Several Makita exploded diagrams and parts lists show this item used in different product families.
Example models this part is documented to fit (representative list from Makita parts diagrams and parts lists): RP1801, RP2301FC / RP2303FC (plunge routers), BHX2501 / PB250 / RBL250 (petrol/hand blowers), DRT50 (cordless trimmer/router variants), RT0700 (trim router) and some 5014/5016-series units. Use this list as practical examples — check your tool’s parts diagram or model number stamping to confirm the same part index is shown for your assembly.
Key specifics for the buyer: part number 213022-3, cataloged by Makita as O RING 3; black rubber construction; sold individually; often shown as replacing or cross‑referenced to internal Makita reference numbers on parts lists. If your tool’s exploded view shows 213022-3 (or “O RING 3”) in the same location you need serviced, this is the correct genuine Makita replacement to restore the original seal.
