PLUG - HEX HEAD (JCB JC40K-04)

A damaged hex head plug can allow fluid leakage, leading to system pressure loss and potential component failure. During routine service, a plug of this type seals threaded openings in fluid reservoirs or housings. The JCB catalog reference for this aftermarket replacement part is JC40K-04. Its plain mechanical function is to close a port or drain hole with a hexagonal drive for wrench installation. A concrete generic failure consequence is that a stripped or cracked plug may cause gradual seepage, resulting in low fluid levels and overheating. Keeping a hex head plug in sound condition helps maintain a closed system and prevent contamination ingress. Verify the serial number or application, then call (562) 693-7748. This item ships at approximately 0.044 pounds.
