Seal O-Rings for Nozzle Holder OM457 EEV
Detroit Diesel

The nozzle holder O-rings are engineered to provide a dependable seal between the nozzle and the associated components in the OM457 EEV system. With an inner diameter of approximately 20.90 mm and an outer diameter of 26.90 mm, these elastomer rings feature a 3 mm cross-section to ensure a secure fit. Their primary function is to prevent fuel or fluid leaks, which is critical for maintaining engine performance, fuel efficiency, and emissions compliance. The elastomer material offers excellent chemical resistance and flexibility, allowing the rings to adapt to temperature fluctuations and mechanical stresses without losing sealing capability. Correct installation of these seals ensures the nozzle operates smoothly without leakages, contributing to consistent engine response.
