The sealing ring K 92030 is a precision–crafted gasket designed to provide a tight, leak-free barrier between the thermometers and their mounting points in the Sulzer/Adriadiesel/Jugoturbina/Zgoda ZV40/48 diesel engine. Built to withstand continuous thermal cycles, pressure variations, and strong engine vibrations, this sealing ring ensures accurate temperature measurement by preventing coolant, oil, or compressed air from escaping around the sensors. By preserving the integrity of the thermometer interfaces and protecting them from wear and corrosion, K 92030 contributes directly to reliable engine monitoring and long-term operational stability.
