Zenoah G450PU Piston Ring K267041211 - No Packing  [K267041211]

Piston Ring Details for G450PU

This piston ring is supplied as the manufacturer's listed spare for G450PU engines and serves to seal the combustion chamber. Good ring condition is essential for maintaining compression and consistent throttle response on nitro remote control vehicles.

Fitment requires inspection of the piston and cylinder for scratches or wear, careful cleaning of contact areas, and correct seating of the ring before final assembly. Because procedures differ by engine build, handle the component with care to prevent nicks, set the ring gap in line with the engine's instructions, and use a fuel-compatible lubricant during initial runs and break-in cycles.

Replacing a degraded ring is a typical maintenance step to bring back compression, decrease smoke and cut oil consumption. The part is provided as a single spare for engine rebuilds and routine service, supplied without packing.
