Yanmar YANMAR - N21 - EXHAUSTVALVE STEM SEAL - 141616-11751
The YANMAR N21 EXHAUST VALVE STEM SEAL (141616-11751) is a precision sealing component designed to regulate lubrication around the exhaust valve stem while preventing oil leakage into the combustion chamber. It ensures controlled oil flow and maintains clean combustion performance.
Used in YANMAR N21 / 6N21 / 8N21 marine diesel engines, this seal supports efficient engine operation by reducing oil consumption, minimizing carbon deposits, and maintaining stable exhaust valve performance under continuous marine load conditions.
