Cummins 3408202 Turbocharger Oil Drain Connection

The Cummins 3408202 is an original equipment manufacturer (OEM) turbocharger oil drain connection engineered for high-horsepower Cummins diesel engines. This component provides the critical return path for lubricating oil from the turbocharger bearing housing back to the engine crankcase. Manufactured to precise dimensional tolerances, it ensures leak-free sealing under high thermal cycling conditions typical of heavy-duty industrial and power generation applications. The assembly integrates directly with the turbocharger center housing and engine block mounting interface. It is a non-serviceable replacement item requiring exact fitment to maintain oil drainage efficiency and prevent bearing starvation or oil leakage. Compatible with Cummins KTA50 and K50G3 engine platforms utilized in generator sets, marine propulsion, and heavy industrial machinery.
