Zenoah K267041211 Piston Ring G450PU (W/O PACKING)  [K267041211]

G450PU piston ring replacement

This piston ring is an RC-scale replacement part named by its manufacturer and model number for use with G450PU engines. As a sealing component inside the cylinder assembly, the ring helps maintain compression and controls blow-by, so it directly affects starting, throttle response and overall engine consistency on nitro remote control models.

When fitting the ring, inspect the piston and cylinder for wear or scoring, clean both surfaces, and ensure the ring seats evenly before final assembly. Install procedures for RC engines vary by build, so handle the ring carefully to avoid nicks, align the ring gap per your engine's service notes, and use fuel-compatible lubrication during initial start and break-in cycles.

In tuning and maintenance, replacing a worn piston ring is a common step to restore compression and reduce smoke or oil consumption. This part is intended for model-scale engine rebuilds and routine maintenance tasks where a direct ring replacement is required, sold as a single RC spare component without additional packing.
