The fit was snug, but required no effort to screw the c/u on. That's bad news about the mighty c/u being a reclaim factory and collecting some of the good stuff. I guess the solution is to buy that adapter you linked, and then cool it somehow, like through water (but doesent water absorb some of the thc/cbd too??) It seems like its hard to get around this, unless u bypass cooling and take the hit direct. This is why I brush the bowl out after EVERY use. You can replace the cooling unit, but not the oven. And now I use basket screens so no need at all, its completed protected.
