Original Makita 213507-9 — O‑Ring 40 (40 mm) — a genuine rubber sealing O‑ring used to restore seal integrity in gear/housing assemblies. It’s the exact replacement O‑ring listed as "O RING 40" in Makita parts diagrams and supplied as a single piece (1 PC).
This O‑ring is commonly used where a compact rubber seal is needed in the gearbox/bearing or seal-holder area; examples of Makita models that list 213507-9 in their parts breakdowns include XDT14 (XDT14M/R/Z), BTD130F and related BTD-series impact drivers, and HR1820/HR1821 rotary hammers.
Designed for a direct fit into the seal groove, the 40 mm rubber O‑ring restores proper sealing to prevent ingress and loss of internal pressure or lubricant; check the old seal for cracking or hardening and replace with the original Makita 213507-9 to regain reliable operation. This part appears across Makita parts diagrams for several impact drivers and hammers.
