What Is a Carb Cap & How Does It Work?

A carb cap (short for carburetor) is a small device that sits on top of the nail or banger during dabbing, much like a lid on a pot. 

Similar to the carb hole in a pipe, a carb cap traps heat, controls airflow, and keeps your concentrate from cooling too quickly, giving you smoother, more flavorful hits.¹ Plus, it’s ideal to help give you more time to finish your dab. A carb cap is handy if you prefer large dabs. (But remember not to overdo it!)

Carb caps are ideal for low-temperature dabs, where consistent heat is key to preserving terpenes and enhancing flavor. By covering the hot nail after dropping in your concentrate, the carb cap helps vaporize the cannabis concentrate evenly, ensuring none is wasted. It also allows you to get the most out of your dabs by maximizing both the potency and the overall experience. Whether you’re a seasoned dabber or just starting out, a carb cap is essential for any setup.²

Using a carb cap with a dab rig or e-rig is straightforward. With dabbing tools like a nectar collector, you won’t need a carb cap. 

Here’s a step-by-step guide to using a carb cap: 

Preheat the sides and bottom of the nail or banger with a butane torch until it reaches your desired temperature. This step usually takes 30-90 seconds.

Before you add your concentrate, wait for the nail or banger to cool. The ideal temperature is 300-450°F (149-232°C). Once cooled, place your favorite cannabis concentrate on the heated nail. If you’re using terp pearls, add them before heating.

If you prefer something simpler than a full dab rig setup, you might opt for a dab pen, which allows you to consume concentrates without needing a nail or carb cap.

After you’ve added the concentrate, immediately place the carb cap over the nail to trap heat and control airflow.

Gently rotate the carb cap around the nail to spread the heat and concentrate evenly. Directional caps allow you to aim the airflow while rotating.

Inhale as you rotate the carb cap to maintain even airflow and temperature, ensuring smooth, flavorful vapor for your smoking session.

leaning your carb caps regularly keeps them in top condition and prevents residue buildup. Here’s how:

• Regular cleaning: Use a cotton swab or paper towel and 90% isopropyl alcohol to clean hard-to-reach areas.
  
  
• Soak for heavy buildup: Let the carb cap soak in isopropyl alcohol overnight until the residue dissolves. Then, wipe the cap with the alcohol and a cotton swab and let it dry.
  
  

Clean your carb caps as needed. They don’t require cleaning after every session unless the buildup is significant.
