Seal Ring - Closing Cover OM457 EEV
Detroit Diesel

The elastomer seal ring for the closing cover of the OM457 EEV is a vital component that ensures an airtight closure, preventing leaks of engine fluids and vapors. With a width of nearly 51 mm and length over 86 mm, this seal provides a secure fit around the cover perimeter, accommodating thermal expansion and engine vibrations. Its 2.7 mm thickness enhances its sealing capability, effectively stopping contaminants from entering sensitive engine parts. Made from high-quality elastomer, it offers excellent resistance to oil, heat, and chemical exposure, which are common in engine environments. Proper sealing with this ring directly impacts engine efficiency, reducing emissions and preventing oil loss. Ensuring a tight seal also minimizes the risk of unfiltered air or moisture entering the system, which could cause corrosion or damage. For dependable performance, Source One Parts Center recommends this seal as a reliable replacement component for your engine’s closure system.
