A spinner carb cap is crucial to get the best dabbing experience with your quartz banger. When used with dab pearls, a spinner cap will zip the pearls around the banger, catching all the oil in it's path. This dramatically improves vaporization. So if you are looking to take bigger dabs at lower temps, you'll want to scoop one below. If you are looking to upgrade or maybe get a spinner carb cap to match your new dab rig, we always have a wide variety of colors in stock. Whether you prefer a disc, ball, or flat style cap, we have you covered here at The Dab Lab.
