Threaded plug for Cummins 6BTAA5.9-C178

The 3046202 threaded plug serves as a mechanical seal for various openings in Cummins engine blocks, crankcases, and fluid systems. Its primary function is to contain oil, coolant, or fuel within the internal circuits while preventing the entry of external contaminants. By providing a secure closure for inspection ports and drainage points, this component maintains the integrity of the engine's fluid management systems.

This part is compatible with Cummins 6BTAA5.9-C178, KTA38C-1050, QSM11-C335, and QSM19-C700 engine models. These engines are frequently utilized in heavy machinery and industrial equipment. The component is designed for installation into threaded ports to ensure a secure fit under standard operating conditions.

Threaded plugs are used throughout heavy machinery to block off unused or service-access ports in pressurized systems. They ensure that internal fluids remain contained while protecting sensitive internal components from debris. Proper installation is necessary to maintain the pressure and sealing requirements of the engine assembly.
