Hitachi/HiKoki Genuine Piston Ring HIT‑6698404 — Spare Part for CG24 & TCG24 Series Grass Trimmers / Brush Cutters & RB24E Blowers

Description

The Hitachi/HiKoki Piston Ring HIT‑6698404 is a replacement OEM spare part used in various 24 cc small petrol engine garden‑tool machines (trimmers, brushcutters, blowers etc.). The piston ring is a critical cylindrical component that fits around the piston in the engine. It ensures a proper seal between the piston and the cylinder wall, reducing blow‑by of combustion gases, maintaining compression, and preventing oil from migrating into the combustion chamber.

A well‑fitting piston ring is essential for engine efficiency, power output, fuel economy, and lower emissions. When the piston ring becomes worn, broken, or loses its sealing capability, you'll notice symptoms like loss of compression, harder starting, increased fuel consumption, smoke from exhaust, and reduced power. This genuine part ensures correct size, material hardness, and compatibility with original engine tolerances.
