Makita 412053-1 Spare Part - PISTON RING 30 HM0810
Original Makita part 412053-1 — Piston Ring 30
Description:
A genuine Makita piston ring (marked “PISTON RING 30”) engineered for the piston/crank assembly of Makita demolition hammers. The ring is a precision-formed sealing ring (30 mm class) that sits around the piston to restore compression and impact efficiency in the cylinder — a direct replacement where the original ring is worn, cracked or lost. It’s sold as a single replacement part and is shown in Makita parts diagrams as the piston ring in the barrel/striker assembly.
Fits (examples):
Common fitment is for the HM0810 family and related models — HM0810, HM0810B, HM0810T and the HMJ/HMJ8 variants that share the same piston assembly. Check your tool’s type plate or parts breakdown to confirm the HM0810-series match.
What to expect:
- Exact replacement for the original Makita piston ring used in the HM0810-series cylinder assembly; listed as part no. 412053-1.
- Supplied as one ring per order; intended for use when rebuilding the piston/striker section of the tool.
Quick tip:
When replacing the piston ring, inspect the mating inner rings and the piston/cylinder surfaces (parts shown alongside 412053-1 in the Makita assembly) for wear — replacing related ring/bushing parts at the same time helps restore full impact performance.
If you need this specific part to get your Makita hammer back to working condition, this is the original Makita piston ring designed for the HM0810-series assembly.
