PLUG - HOLLOW HEX (JLG JL102856SJ)

A damaged hollow hex plug can allow fluid or debris to bypass the sealed port. During inspection, a plug of this type may show thread wear or surface corrosion. The plug's plain mechanical function is to seal a threaded opening by compressing a gasket or O-ring. A concrete generic failure consequence is that a loose or missing plug can cause gradual pressure loss in a closed system. Keeping a hollow hex plug in sound condition helps maintain system integrity. This aftermarket replacement part references JLG catalog number JL102856SJ.
