PLUG - EXPANSION (CAT CT0042012000)

CT0042012000: A damaged expansion plug can allow coolant or oil to leak from core passages. During inspection, an expansion plug may show signs of corrosion or pitting that compromise its seal. The plug's plain mechanical function is to seal cored holes in castings after the casting process. A concrete generic failure consequence is that a leaking plug can lead to overheating or fluid loss in the system. Keeping an expansion plug in sound condition helps prevent unexpected downtime from fluid leaks.
