Carb Caps

What Is a Carb Cap?

A carb cap is a small accessory placed on top of a quartz banger after you apply concentrate. It limits airflow and creates controlled pressure inside the banger, allowing concentrates to vaporize efficiently at lower temperatures. Carb caps also direct airflow to move concentrate across heated surfaces for more complete extraction.

Why Carb Caps Matter for Low-Temperature Dabbing

• Better low-temperature performance – improves vaporization without relying on excessive heat.
• Flavor preservation – controlled airflow helps protect delicate terpene profiles.
• Higher efficiency – more complete vaporization can reduce puddling and waste.

Material & Compatibility

• Materials – Croia Glass focuses on premium borosilicate glass and quartz for heat resistance and flavor neutrality.
• Seal and fit – a carb cap must match the banger’s opening and rim style to create an effective seal.
• Terp pearls – many caps are designed to spin pearls for more even heat distribution and reduced pooling.

How to Choose the Right Carb Cap

• Match your banger type – flat-top and beveled-edge bangers typically use bubble, directional, or spinner caps.
• Match the opening size – your carb cap should sit securely on the rim with minimal air leakage.
• Decide if you use terp pearls – spinner caps are ideal for consistent pearl rotation; bubble caps work well with manual control.
• Consider your pull strength – if you tend to pull hard or use multiple pearls, trap/tether styles help keep pearls under control.

How to Use a Carb Cap

1. Heat your quartz banger and allow it to cool to your preferred temperature.
2. Apply concentrate into the banger.
3. Place the carb cap on the banger to create a controlled seal.
4. Gently rotate or angle the cap to guide airflow and move concentrate across heated surfaces.

Temperature Guidance

• Low-temp flavor – commonly around 450–550°F
• Balanced vapor – commonly around 550–650°F
• High-temp intensity – commonly 650°F+

For consistency, an IR thermometer or terpometer is recommended. Temperature preference varies by banger thickness, concentrate type, and airflow style.

How to Clean a Carb Cap

1. Allow the cap to cool fully.
2. Wipe residue with a cotton swab.
3. Soak in isopropyl alcohol (91%+) for deeper cleaning.
4. Rinse with warm water and air-dry completely before reuse.

Carb Cap FAQ

Is a carb cap necessary for dabbing?
It is highly recommended. Carb caps improve airflow control, enable more efficient low-temperature vaporization, and help reduce leftover residue.

Does carb cap material affect flavor?
Yes. Quartz and borosilicate glass are flavor-neutral and heat-resistant. Low-grade materials can impact heat behavior and may introduce unwanted taste.

What is the difference between a bubble cap and a spinner cap?
Bubble caps provide manual directional control, while spinner caps use angled airflow to automatically spin terp pearls for more uniform heating.

Do carb caps fit all bangers?
No. A proper seal depends on the banger’s rim style and opening size. Choose a cap designed for your banger type and diameter for best performance.
