I had to replace this nut on my spa because of after refilling the tub for the season, the old nut leaked significantly. It was a difficult area to work on-with room only for one hand & arm. It took three attempts to get the nut to lock down properly. I used Teflon tape, wrapped on the factory PVC pipe connecting and then was able to get the nut to lock down and not "pop" loose. I'm really glad that my hottub is located inside the house!
