The Sulzer ZV 40/48 diesel engine incorporates precision-engineered components like the joint ring, designated by code K 92147, specifically designed for SERTO manometer screw connections. This joint ring ensures a secure and leak-proof seal for pressure gauge connections, maintaining the integrity of the monitoring system under high-pressure and high-temperature conditions. Manufactured to withstand extreme operational demands, the joint ring prevents leakage and ensures accurate pressure readings, which are critical for engine safety and efficiency. Routine inspection and timely replacement of this component are essential to sustain optimal engine performance and avoid potential system failures in demanding marine and industrial environments.
