Dab rigs (often called oil rigs) are a type of water pipe - similar to a bong, but designed specifically for use with waxes, oils, dabs, and concentrate use. They come with a quartz banger, or dab nail. Dab rigs are often smaller and more portable than bongs, and features percolators with more airflow and less filtration. That is because concentrates do not require as much filtration as their bong counterparts and the harsher combustible material smoke. Dab rigs are designed to maximize the flavor of your dabs and make a big difference when smoking your concentrates than using a bong.
