Pressure gauge pipes, code 235216, are essential components designed to transmit pressure signals from key points within the MAN L21/31 engine systems to monitoring instruments. These pipes ensure accurate and consistent measurement of pressures in lubrication, fuel, or air circuits, enabling operators to monitor engine performance and detect irregularities at an early stage. Manufactured with high precision from corrosion-resistant materials, they are capable of withstanding pressure fluctuations, vibration, and demanding operating environments. By maintaining reliable signal transmission and protecting system integrity, pressure gauge pipes support effective monitoring, preventive maintenance, and the overall reliability of the engine.
