An adapter is a glass piece that you can put on a bong or dab rig that changes the sex of the piece.

They put the adapter on their dab rig because the only boal they had did not match the sex of the joint.

Any type of tube or additional glass pieces you attach to water pipes to change the sex.

Pass me the vape adapter I want to rip this thing like crazy!
