Exhaust Valve Seat Ring - Cylinder Head (Without Valve) OM904
Detroit Diesel

The exhaust valve seat ring for OM904 engines is designed to provide a reliable sealing surface between the valve and cylinder head. With a height of 8.10 mm, an inner diameter of 31 mm, and an outer diameter of 40.07 mm, it fits into the cylinder head to support the exhaust valve seat. Its role is to endure high combustion temperatures and pressures, preventing exhaust gases from leaking and ensuring efficient engine operation. The seat ring’s material and precise dimensions are vital for maintaining proper valve seating and combustion chamber integrity. Replacing worn or damaged seat rings restores optimal sealing and prevents loss of compression, which can compromise engine power and efficiency. Sourcing this component from Source One Parts Center guarantees compatibility and high-quality standards necessary for heavy-duty diesel engines, ensuring long-term performance and reliability.
