Adapters like these make it possible to connect pieces that otherwise would not be connectable. For instance, two female joints can't typically connect with one another, but this single piece allows for it to happen. The piece is short, but it still drops the nail end below the rest of the piece, which only protects the user and the pipe itself while a torch is being used to heat the quartz nail. Such heat could easily damage the standard glass of the remainder of the pipe, so an adapter like this helps by allowing the user to heat the dish further from the main pipe.
This piece is American-made and uses incredibly precise joints for excellent seals and smooth hits. It not only increases the lifespan of most pieces, but it also reduces the amount of heat that must be used during the vaping process. Adapters like this can expand the utility of your collection while improving the efficiency of your processes altogether. Add one to your set of glass components today.
