Carb Caps & Dab Caps

Carb Caps and Dab Caps for Low-Temp Concentrate Sessions

A quality carb cap is one of the most impactful upgrades you can make to your dab setup. Carb caps work by restricting airflow over your heated quartz banger, creating a pressurized environment that allows concentrates to vaporize at much lower temperatures. Low-temp dabs preserve the full terpene profile of your concentrates, delivering richer flavor and smoother vapor compared to high-temp rips that burn off the best parts.

AFM carries a full range of carb cap styles to match every banger and every dabbing preference. Directional carb caps let you control airflow with precision, steering vapor around the banger walls for complete coverage. Bubble carb caps create a spinning vortex that keeps concentrates moving and vaporizing evenly. Spinner carb caps and turbo caps pair best with terp pearls, using airflow to spin the pearls around the banger floor and eliminate cold spots. All AFM carb caps are crafted from borosilicate glass for clean, inert vapor and easy heat resistance.

Pairing the right carb cap with your banger setup makes a noticeable difference in how efficiently you use your concentrates and how good each dab actually tastes. Whether you're running a flat-top, a terp slurper, or a beveled edge banger, there's a cap in this collection built for it. If you're just getting into concentrates, adding a carb cap to your dab rig setup is one of the easiest and cheapest ways to immediately improve your sessions.

Carb Cap FAQs

What does a carb cap actually do?
A carb cap restricts airflow over your heated banger, creating a small pressure drop that lets concentrates vaporize at much lower temperatures. Low-temp dabs preserve the full terpene profile, which means richer flavor and smoother vapor compared to high-temp rips that burn off the best parts.

Directional, bubble, or spinner carb cap: what's the difference?
Directional caps let you steer airflow around the banger walls so every drop of oil vaporizes. Bubble caps create a spinning vortex that keeps concentrates moving and burning evenly. Spinner caps pair with terp pearls and use airflow to spin the pearls around the banger floor, eliminating cold spots. Most dabbers run one of each.

What size carb cap do I need for my banger?
Match the cap to the inner diameter of your quartz banger, not the joint size. AFM carb caps come in sizes that fit 10mm, 14mm, and 18mm bangers. Standard flat-top bangers usually take a 25mm to 30mm cap. Check the product spec on each cap and on your banger before buying.

How do I use a carb cap?
Heat your banger, let it cool 30 to 45 seconds (longer for thicker quartz), drop in your concentrate, then place the carb cap on top. Spin a directional cap as you inhale to move the vapor around the banger walls. Keep the cap on until you've pulled all the vapor.

Glass vs quartz carb cap: which is better?
Glass carb caps are clear and let you see what's happening inside the banger, which makes them the most popular choice. Quartz caps handle higher temperatures and pair best with quartz bangers for thermal consistency. Both work. Pick based on whether you want visibility (glass) or maximum heat tolerance (quartz).
