A dab rig, also called a wax rig or concentrate rig, is a smoking tool made for vaporizing concentrates like wax or oil. It’s a bit different from your typical bong or water pipe, which is mainly used for dry herbs. Concentrate rigs are usually more compact than bongs. They come with a smaller base, a nail (like a quartz banger or a titanium bowl), and a slim neck that leads to the mouthpiece.
