Cylinder Head Seal O-Ring (Without Constant Throttle, OM460)
Detroit Diesel

This green elastomer O-ring is designed specifically for sealing the cylinder head in engines with constant throttle configurations. Its compact dimensions—inner diameter of 9 mm and outer diameter of 12.40 mm—allow it to fit precisely into designated grooves, providing an effective barrier against coolant, oil, and combustion gases. The elastomer material offers excellent flexibility and chemical resistance, critical for withstanding engine heat and exposure to various fluids. Proper sealing with this O-ring prevents leaks that could compromise engine performance, cause overheating, or lead to internal damage. Its reliable performance under high pressure and temperature variations makes it a vital component during assembly and maintenance. Trusted by professionals, Source One Parts Center offers this seal to help maintain optimal engine operation and prevent costly repairs caused by seal failure.
