The Elkhart 65549307 is the 750 GPM fixed stem head for the Nitro HD 7000-EHD electric nozzle. Elkhart identifies this exact stem for a rated flow of 750 GPM at 100 PSI nozzle base pressure.
Use this component only in the compatible 7000-EHD nozzle assembly. Changing the stem alters the nozzle’s flow profile, so the pump, monitor and piping must support the selected flow safely.

Installation and Service Checks
| Depressurize |
Shut down the pump, isolate the water supply and relieve pressure before nozzle service |
| Disconnect power |
Disconnect electrical power to the nozzle before replacing the stem |
| O-ring |
Confirm an AS568-012 O-ring is installed in the groove on the threaded end of the stem |
| Thread locking |
Follow the current Elkhart manual for the specified thread-locking compounds and tightening procedure |
| Flow check |
Verify stream quality and rated performance after reassembly; incorrect stream-shaper position can alter flow |
