I use Protank heads in my EVODs. I have LOTS of them (EVOD/clones). Not sure about the bottle caps; the ones at Vapor King have a lip on the sides; look at your current tips and if they have that lip on the sides I would guess, just a guess, they would. Also note these do not work with a lid on the bottle. These are similar but lids fit. fasttech, so not the fastest to get... these also have the "lip".
