Restore proper compression and support dependable engine performance with Namura NA-50012R piston rings. Designed specifically for Namura pistons, this ring set is manufactured to match the piston application and provide a reliable sealing interface between the piston and cylinder wall.
The 86.93 mm size is intended for compatible Namura piston assemblies requiring this ring specification. These rings help maintain combustion pressure, manage oil control, and support efficient transfer of heat from the piston to the cylinder. For proper fitment, verify the piston model, bore specification, ring configuration, and service requirements before installation.
Namura NA-50012R piston rings are intended for replacement or rebuild applications where worn, damaged, or improperly sealing rings may contribute to reduced compression, increased oil consumption, or diminished engine performance. Installation should follow the engine manufacturer’s procedures, including correct ring orientation, end-gap inspection, cylinder preparation, and break-in recommendations.
