Yanmar YANMAR - N21 -SQUARE RING - 146673-51801
The Square Ring is a critical sealing component used in YANMAR N21 / 6N21 / 8N21 marine diesel engines to prevent leakage of fuel, lubricating oil, coolant, or compressed air between mating surfaces. Its square-profile design provides enhanced sealing efficiency under demanding operating conditions.
It helps maintain system pressure, reduces fluid loss, and ensures reliable engine performance in marine applications.
