PLUG (CAT CT28858)

A worn plug can allow debris or moisture into a sealed cavity, leading to corrosion or system contamination. The aftermarket replacement part cross-references CAT part number CT28858. This plug type serves as a closure component that blocks an opening in a housing or port. Its plain mechanical function is to seal a threaded or smooth bore against leakage. A generic failure consequence is that a missing or deteriorated plug may cause loss of pressure or fluid ingress. Keeping a plug in sound condition helps maintain the integrity of the enclosed area. Verify the serial number or application, then call (562) 693-7748.
