The piston ring H 34027 is a vital sealing and wear component of the Sulzer ASL25 piston assembly, designed to maintain optimal compression and control oil consumption within the cylinder. Manufactured from high-quality, wear-resistant material, this piston ring provides effective sealing between the piston and cylinder liner under high pressure and temperature conditions. By minimizing blow-by gases, reducing friction, and ensuring efficient heat transfer from the piston to the cylinder wall, H 34027 plays a key role in combustion efficiency, emission control, and long-term durability of the engine.
