One New Aftermarket Replacement Exhaust Valve Seat Insert for Caterpillar (Cat) Engines
This aftermarket exhaust valve seat insert (Insert-Exh) replaces Caterpillar (Cat) OEM part number 216-8333. The exhaust valve seat insert is a precision cylinder head component that provides a hardened seating surface for the exhaust valve to close against, maintaining a tight combustion seal under the extreme heat and pressure of diesel engine operation. Proper seating prevents compression loss, reduces valve recession, and extends cylinder head service life. This part is sold individually.
