One New Aftermarket Replacement Exhaust Valve Seat Insert for Caterpillar (Cat) C9 Diesel Engines
This exhaust valve seat insert (Insert-Vlv Ex) is a press-fit cylinder head component for the Caterpillar C9 diesel engine. Seated into the cylinder head counterbore, it provides a precise, durable sealing surface for the exhaust valve, dissipating high exhaust temperatures and preventing wear to the cylinder head.
