Product Description
The 6212-41-4540 Valve Seal is a precision engine component installed on the valve stem of intake and exhaust valves in Komatsu 6D140 diesel engines. It prevents engine oil from entering the combustion chamber along the valve stem, maintaining proper compression and preventing oil consumption, carbon buildup, and spark plug fouling.
This is a brand new, 100% tested replacement valve seal that serves as a direct replacement for the original unit. It is manufactured from high-quality fluoroelastomer (FKM) or polytetrafluoroethylene (PTFE) materials with precision-machined steel inner rings, featuring excellent heat resistance, oil resistance, and long service life under high-temperature engine operating conditions.
