Carb cap

A carb cap is a cylindrical glass accessory used when dabbing cannabis concentrates to better regulate airflow and retain heat in the nail or banger bowl. Carb caps temporarily restrict outside air flow when capping a heated nail, allowing the user more time to fully inhale a large dab.

Carb cap design creates an enclosed heated environment, similar to how placing a finger over a pipe's carb hole functions. Directional airflow carb caps with angled fins provide precise airflow control. Proper technique with a carb cap can significantly improve vapor production, terpene flavor preservation and overall consistency when dabbing.

Beyond retaining heat, carb capEXTRA airflow restriction increases vapor pressure for bigger rips. Paired with optimal heating, carb caps give dabbers ultimate control over the vaporization experience from start to finish.
