Listed under the manufacturer's model number, this piston ring is a direct replacement option for G450PU engines used in nitro remote control models. The ring functions as the internal seal in the cylinder and has a direct effect on compression, blow-by control and engine running consistency.
During installation, check piston and cylinder surfaces for scoring, thoroughly clean mating faces, and ensure the ring is seated evenly before completing assembly. Installation methods vary with engine builds, so protect the ring from nicks, align the gap to the service guidance, and apply fuel-safe lubricant for initial start and break-in operation.
As part of routine servicing or a rebuild, fitting a new piston ring is an effective way to restore compression and lower smoke or oil consumption. This item is sold as a single RC spare component and is provided without additional packing.
