Cummins 5264945 Turbocharger Oil Drain Connection

The Cummins 5264945 is a turbocharger oil drain connection fitting. It facilitates the return of lubricating oil from the turbocharger bearing housing back to the engine crankcase. Manufactured to OEM specifications for precise fit and sealing performance. Compatible with Cummins ISDe engine series. Constructed from durable cast iron or steel alloy to withstand thermal cycling and oil pressure. This component is critical for preventing oil accumulation in the turbocharger, which can lead to seal failure and reduced engine performance. It serves as a direct replacement for the factory-installed drain connection on applicable Cummins ISDe engines.
