I'm ordering an extreme q vaporizer right now, and i want to buy a bong to attach to it. The adapter i'm gonna buy fits a joint size of 14mm. looking at grasscity's bongs, they only have 14.5mm. is there supposed to be that size difference so that they fit together? or will the 14mm adapter not fit airtight into a 14.5mm piece? this is the adapter: https://www.planetvape.ca/extreme-q-...l-adapter.html also, any suggestions for bongs, 50-100 dollars? i've never bought or used a bong before so i'm sort of lost.
