Exhaust Valve Seat Insert - 5.5 to 5.7 Gauge Height
Detroit Diesel

This exhaust valve seat insert is designed with a gauge height between 5.5 and 5.7, optimized for sealing and heat resistance in high-temperature combustion environments. Its dimensions of approximately 6.31 mm in width and 41.35 mm in length allow for a precise fit within the valve seat area, ensuring effective sealing of exhaust gases. Made from high-strength steel, it resists thermal fatigue, corrosion, and wear, thereby extending the service life of the valve assembly. Proper installation of this insert maintains compression integrity, improving engine efficiency and power output. Its durability under intense thermal cycling makes it indispensable for maintaining optimal exhaust flow and minimizing emissions. Sourced from trusted suppliers like Source One Parts Center, this component supports the long-term reliability of heavy-duty diesel engines.
