Loctite on alky nozzle?

[434nova]

Do you guys use loctite on the alky nozzle? I did for peace of mind but wonder if it’s really needed. Anyone ever have a nozzle come loose on them?

yes loktite .. npt fittings seal on the threads when fully engaged but with the washers the npt design really isnt able to get the thread seated so a little loktite ensures a good seal
