The Exhaust Valve Seat Insert is located in the cylinder head and provides a durable seating surface for the exhaust valve. The exhaust valve, which allows the burnt gases to exit the combustion chamber, opens and closes against the valve seat insert. The insert helps create a tight seal between the valve and the cylinder head, preventing any leakage of gases during the combustion process.Attributes:• Withstand mechanical stress, without compromising their performance or safety• Maintain their original shape even when compressed over time Applications:The Exhaust Valve Seat Insert is used to prevent the impact of the valve into the cylinder head.
