The Cummins 3040818 Threaded Plug is a critical component for the structural integrity of your engine's fluid management system. In the high-output KTA38-G series, the engine block contains various ports used for machining, sensor mounting, or fluid drainage. This plug is the primary safeguard that keeps engine oil and coolant where they belong, preventing external leaks that could lead to environmental hazards or engine overheating.
Using the genuine 3040818 ensures that the plug’s material hardness matches the block’s casting, preventing thread damage (galling) that often occurs with off-brand hardware.
The 3040818 Cummins Threaded Plug is compatible with the following engine power models:
Cummins: KTA38-G1, KTA38-G2, KTA38-G2A, KTA38-G4, KTA38-G, KTA38-G5
Note: Please confirm that your engine model is compatible before purchasing. You can also contact customer service for assistance at any time.
