Yanmar 119025-01331 Cylinder Head Gasket

The Yanmar 119025-01331 cylinder head gasket is designed to seal the interface between the cylinder block and cylinder head on Yanmar 3TNM72 series industrial diesel engines. It prevents leakage of combustion gases, coolant, and engine oil under high thermal and mechanical loads. This gasket supersedes part number 119025-01332 and is constructed from multi-layer steel (MLS) to withstand the high compression ratios of modern diesel engines. It features precision-formed sealing beads around cylinder bores, coolant passages, and oil galleries. Direct replacement for Yanmar engines including 3TNM72, 3TNM72-AWM, 3TNM72-AWK, 3TNM72-AFF, 3TNM72-APB, 3TNM72-APB1, 3TNM72-ATE, 3TNM72-BAJ, 3TNM72-BKK, 3TNM72-AAPL, 3TNM72-HA, and 3TNM72-GGE variants.
