Threaded plug for Cummins 6BTAA5.9-C178

The threaded plug 3055069 acts as a secure seal for various openings found throughout the engine block, cylinder head, and auxiliary systems. It is used to close off inspection ports, drainage points, filling locations, or mounting positions for sensors that are not required for a specific engine configuration. By providing a tight seal, this component ensures the proper containment of internal fluids such as oil, coolant, or fuel while preventing external contaminants from entering the engine system.

This component is compatible with several Cummins engine models, specifically the 6BTAA5.9-C178, KTA38C-1050, QSM11-C335, and QSM19-C700. These engines are widely utilized in heavy machinery applications, including cranes, excavators, and power generation equipment. The plug features precise threading to ensure a secure fit within the corresponding ports, maintaining system integrity under standard engine operating pressures and temperatures.

Threaded plugs are fundamental to maintaining the fluid circuits of an engine. They allow for modularity in engine design by enabling access to internal galleries for maintenance or diagnostic purposes while ensuring a leak-free environment during operation. Proper installation of these plugs is necessary to prevent fluid loss and maintain the pressure levels required for the engine to function correctly.
