Overview:
The Oil Pressure Switch for Yanmar 3TNV70-STB and 3TNV76-KWA engines is a Genuine Yanmar part designed to protect your engine by signalling when oil pressure drops below a safe level. Built with a robust metal body and a sealed polymer insulator, it withstands vibration, heat, and oil exposure common in plant, turf, and industrial applications. The M10 thread ensures a secure, leak-tight fit in the factory port on compatible Yanmar TNV and TNE series diesel engines.
