Oil Pipe, Dab Rig or Oil Rig is a pipe designed for vaporizing cannabis concentrates, Like a bong, an Oil Rig filters the vapor through the water at the base. Instead of a bowl that we find on regular Water Pipes, Dab Rigs require a glass, quartz, ceramic, or titanium nail, or banger, to hold or “dab” the concentrate, and also a dabber tool, and a torch lighter for proper heating.
