Chrome Plated Lance Socket is used as a 1/4" threaded joint to connect threaded nozzles similar to a nozzle holder. These sockets are common in sewer and mining applications where a fixed install with a specific threaded nozzle is desired. This setup is permanent in order to eliminate an accidental loss of a nozzle while performing exploratory and excavation services. Threadlock/ Loctite is recommended for install.
