The sealing ring K 92030 is a precision gasket designed to ensure a leak-free and thermally stable interface between the engine thermometers and their mounting points on the Sulzer/Adriadiesel/Jugoturbina/Zgoda ZV40/48 diesel engine. Engineered to resist high temperatures, pressure fluctuations, and continuous vibration, this sealing ring prevents coolant, oil, or compressed air from escaping around temperature-measuring sensors. By maintaining accurate thermal readings and protecting the sensor seating surfaces from wear and corrosion, K 92030 contributes directly to reliable engine monitoring, stable operation, and early detection of abnormal thermal behavior in heavy-duty marine and power-plant applications.
