Makita genuine X‑Ring 213517‑6 (X‑Ring 40) — precision sealing ring for Makita demolition hammers. This molded X‑profile seal restores the piston/cylinder sealing that keeps impact energy consistent and prevents oil/air leakage under heavy duty use; it’s the exact replacement used on Makita hammer assemblies. Nominal size listed as “40” (40 mm class X‑ring).
Fits a range of Makita demolition hammers — examples include HM1500 / HM1500B, HM1810 machines (check your model designation to match the part callout).
Why this part matters: swapping the worn or hardened X‑ring with this original Makita part returns sealing integrity and impact performance without needing further machining or modification. Supplied as the single genuine Makita replacement X‑ring 213517‑6.
