The piston rings for Namura help restore lost compression by sealing the gap created after machining the cylinder block.\u003c\/p\u003e\u003ch4\u003eOverview\u003c\/h4\u003e\u003cp\u003eThe .020 over bore piston rings for Namura are critical for engine performance after a cylinder bore service. Owners rely on these piston rings for Namura to achieve a tight fit that prevents combustion pressure loss during high-speed operation.
