Detroit Diesel

These elastomer O-rings are essential sealing components designed specifically for the closing cover of OM457 EEV systems. With an inner diameter of 25 mm and an outer diameter of 29.60 mm, along with a wall thickness of 2.30 mm, they create a tight seal that prevents fluid or gas leaks during engine operation. Their flexible construction allows them to accommodate slight imperfections and thermal expansion, maintaining integrity over prolonged use. This sealing function is vital for maintaining optimal pressure and preventing contamination, which could compromise engine efficiency and longevity. Proper sealing also reduces the risk of environmental emissions, aligning with regulatory standards. Source One Parts Center offers these O-rings as reliable replacements, ensuring that precision and durability are maintained in your engine's vital sealing points, thereby safeguarding your investment and operational uptime.
