Makita O RING 12 AN504/HM1203/HM1213 - 213118-0

Original Makita O‑Ring — part no. 213118-0. A small, black rubber sealing ring listed by Makita as "O RING 12" (12 mm ), made to restore leak‑free seals in the tool’s piston/pipe or gasket locations.

This is the original Makita replacement O‑ring used across a range of rotary/hammer drills, demolition hammers, impact drivers and some grinders. Example models that use this part include HR5211C rotary hammer, HM1213C demolition hammers, HR4510C/HR4511C, HR5210C, DHR182, DTD171Z — useful as a direct-fit sealing ring when the old seal is cracked, flattened or missing.

Simple to fit and inexpensive to replace, this genuine Makita O‑ring gets a worn seal back to spec and helps prevent loss of performance or internal contamination. For handheld service, clean the mating surfaces and install the ring without twisting to ensure a reliable seal.
