Review on Maximizing Performance: Plasma Electrode Nozzles - Top Consumable Accessories by Jesse Azuse

Electrode and cup appear to fit but absolutely nothing ceramic will fit. Either the threads didn't match, or the ones that started to screw in were too thick on top and didn't screw in all the way. Only a millimeter thicker but they don't fit enough. Went to another brand and was 50/50 with ceramic. Quality control should work better. I also tested them on 3 different brands of torch heads with the same problem. So the problem is not in the burner head. Return for refund. It's hard to find a quality brand without spending a fortune...
