I've been looking into buying a new bong but I want to know if I could attach a pre-cooler to the one I like. Click Here What size pre-cooler fits this one?
A precooler is already attached to that piece. Typically pre-coolers, ashcatchers etc work on ground glass connections (GonG -- Glass on Glass) and this looks like an acrylic piece with a metal bowl, meaning you couldn't attach anything more to it unless you wanted to do it yourself as a project thing. Moral of the story, it has a pre-cooler, but if you want more than that you should get a bong with a ground glass connection.
Thanks, one question about the bongs with a ground glass connection then I'll be good. Would a 14.5mm attachment fit into a 18mm bong?
