a little bit ago i knocked my bong over while i was getting up to get some water in the middle of the night and now im shopping around for a new downtube cuz my throat is really getting destroyed. my only other piece is a 18" steam roller ive been looking at getting one of those roor diffusers

my question is- has anyone done the same thing and replaced it with a roor diffuser?? and how do i figure out if its 14.5 or 18.8mm ???
