Makita 213832-8 — O‑Ring 13 (genuine Makita)

Keep your Makita rotary/combination hammer sealing properly with this original Makita O‑Ring (part no. 213832-8), listed by Makita as "O‑RING 13" (13 mm nominal size). It fits into the piston/striker area to restore the pneumatic seal and help maintain full hammer action and impact performance.

This genuine Makita replacement is supplied individually (quantity 1 on the parts breakdown) and is the exact O‑ring called out in Makita parts diagrams for several 18 mm-class hammers — for example: DHR182, HR1840, HR1841F and HR010G — check your tool’s exploded parts list to confirm the match in the piston/striker section (position shown as 039 or similar).

If your hammer is showing reduced impact or oil/air leakage around the piston area, replacing this 13 mm O‑ring will typically restore proper sealing and hammer action. The part is the exact Makita part number to order when your parts breakdown lists 213832-8 (O‑RING 13).
