How to Use a Carb Cap for Dabs and the Science Behind How They Work
The widespread use of concentrates has spurred a revolution in the methods of smoking concentrates and accessories used for dabbing. Carb caps have become a critical part of every dabber’s arsenal because of the science behind vaporizing wax concentrates. Even though carb caps are a relatively new development in the mainstream smoking community, there has been an evolution in the design of carb caps that has been closely correlated with the development of nails and bangers.
Dabbers have progressed from nails to bucket style quartz bangers to gavel style quartz bangers. With this evolution, carb caps have evolved from straight carb caps to what is today the most popular, glass directional airflow carb caps. They also make the vapor swirl around in the banger and make the dab rig all milky white.
Bubble carb caps and trunk carb caps, the two types of directional carb caps, are now the gold standard in dabbing concentrates and they work perfectly with a gavel banger. Carb caps are not only a cool accessory, they improve the experience by causing the wax concentrates to vaporize at a lower temperature thereby improving the flavor and smoothness.
The cap increases the suction and lowers the ambient air pressure in the banger. Vapor pressure determines the relationship between temperature and pressure necessary to vaporize something. As the banger is capped by the carb cap, ambient pressure is decreased and the airflow is directed which allows the excited evaporating oil to vaporize at a temperature that it would otherwise be unable to vaporize at under high pressure. This makes for cooler, smoother, tastier terpene-rich dabs!
The lower pressure causes the oil molecules to bond easier with air, allowing the oil to vaporize with the directional flow of air. This directional airflow from the carb cap also pushes the oil around the hot banger finding the dry hot spots to continue vaporization as the banger cools further. depending on the size of the dab and the temperature, you may have just one hit or you may have multiple hits from each dab.
Eventually, you will begin to see darkening of the oil after some time but should not see immediate total vaporization and charring or you are likely using too high of a temperature on your banger (unless you just prefer high-temperature dabs). Certain dab smokers prefer to use swabs to wipe out the excess oil, while others seem to reheat until they vaporize and char all of the oil. This is a question of taste and health versus frugality and economics. But I will let you decide.
There are multiple variations of the carb cap but there are essentially three style variations: straight (or side) carb caps, trunk carb caps, and bubble carb caps. The second and third examples are both directional airflow carb caps while the first one typically is not. Take a look at some pictures below:

Like I said, the directional carb caps such as bubble carb caps and trunk carb caps used with gavel style bangers are the preferred choice amongst experienced dab smokers. Many people who have the privilege of trying both of these options tend to lean towards the bubble cap as their favorite, due to its ease of use, long reach, and flexible control providing an arguably more ideal air pressure and airflow. But now you have the knowledge necessary to make your own decision.
