Yanmar 119625-11870 119625-11880 Injector Nozzle Protector and Seat Kit

This kit comprises the nozzle protector (119625-11870) and nozzle seat washer (119625-11880), essential for maintaining fuel injector sealing performance in Yanmar diesel engines. The protector shields the nozzle tip from combustion heat and pressure, while the seat washer ensures a precise metal-to-metal seal between the injector and cylinder head. Manufactured to OEM specifications using heat-resistant alloy steel for the protector and precision-ground steel for the seat washer. The seat washer features dimensions of 16.5 mm outer diameter, 10.7 mm inner diameter, and 2.35 mm thickness. Designed for direct replacement during injector overhaul or cylinder head service to prevent combustion gas blow-by and ensure correct injector protrusion. Compatible with a wide range of Yanmar TNE, TNV, JH, and 6LY series engines used in industrial, marine, and agricultural applications.
