395-4261: Engine Valve Seat Insert

Description: A cylinder head valve seal, also known as a valve stem seal, is a small but crucial component in an internal combustion engine. It is located at the top of the engine cylinder head and is responsible for sealing the gap between the valve stem and the valve guide. Attributes: • Made of durable material, such as rubber or synthetic rubber with high-temperature resistance. • Capability to withstand expansion and contract without losing their sealing ability. Applications: A cylinder head valve seal is used to prevent oil from entering the combustion chamber while also preventing excessive oil consumption. It achieves this by providing a tight seal around the valve stem, preventing oil from leaking into the intake or exhaust ports during engine operation and it is widely used in Cat G3516C and G3520C Generator Set, G3520C Engine (Piston).
