Description

Overview:
The Piston Ring for Makita RST210 Brushcutters (part number 257320-5) is a genuine Makita replacement designed to restore correct compression in small petrol engines. This circular metal ring fits into the piston groove to seal the combustion chamber, helping the engine start reliably and produce stable power. Built for demanding landscaping and site work, it is suitable for two-stroke machines such as the Makita RST210 and HTR4900. The ring measures 32.5 mm outer diameter (1.28 in) and 30.0 mm inner diameter (1.18 in). Manufactured to tight tolerances for a secure fit, it withstands heat, friction and fuel/oil exposure commonly encountered in brushcutters and hedge trimmers, supporting long service life and consistent performance when replacing a worn or damaged ring.

Key Features:
- Genuine Makita part for assured compatibility and reliability
- Part number: 257320-5 (also referenced as 2573205)
- Restores correct engine compression for easier starting and steady power
- Helps reduce blow-by, power loss and excessive fuel consumption
- Durable metal construction for heat, friction and wear resistance
- Dimensions: 32.5 mm OD (1.28 in), 30.0 mm ID (1.18 in) for accurate fit
- Precision-made to match Makita specifications for the listed models
- Suitable for routine top-end service or full engine overhaul
- Straightforward to install during piston service with standard workshop tools
- Supports cleaner running and consistent performance in tough conditions

Typical Applications:
Used during engine maintenance or repair when compression has dropped due to ring wear, scoring or breakage. Ideal for brushcutters and hedge trimmers operating in landscaping, grounds maintenance, agriculture and construction site work. Fit this ring during decarbonising, piston replacement or cylinder refurbishment to recover starting performance, throttle response and fuel efficiency on compatible Makita petrol machines.

Also known as:
Piston sealing ring, cylinder sealing ring, bore ring, engine piston ring, top ring, ring set component, piston groove ring, engine seal ring. These terms are commonly used for the same part that maintains the seal between the piston and cylinder wall in small petrol engines.
