A carb cap turns your banger into a low-temp dabbing machine — by restricting airflow it lowers the pressure inside, so concentrate vaporizes at a lower temperature for far better flavor. Below you'll find directional and bubble caps in collectible glass designs, shipping fast from the US.

How a carb cap works
A small accessory that makes a big difference to flavor:
Low-temp dabs
Capping traps heat and lowers pressure, vaporizing concentrate at a lower temp for smoother, tastier hits.
Directional
Angled-spout caps let you push airflow around the banger so nothing is left behind.
Bubble & spinner
Bubble caps spin terp pearls to keep oil moving; many double as a stylish display piece.
Fit
Most caps fit standard 25mm quartz bangers — check your banger diameter before buying.

Frequently asked questions
What does a carb cap do?
It covers your banger to restrict airflow and lower the internal pressure, letting concentrate vaporize at a lower temperature for better flavor and less waste.
Do I need a carb cap to dab?
Not strictly, but it dramatically improves low-temp dabs — you get more flavor, smoother hits and you use less concentrate.
What size carb cap do I need?
Match it to your banger. Most modern quartz bangers are 25mm, and most caps are made to fit that standard — check the diameter to be sure.
What is a directional carb cap?
One with an angled spout you rotate to steer airflow around the banger, helping vaporize every bit of concentrate evenly.
Carb cap vs terp pearls — do I need both?
They work together: a spinner carb cap directs air to spin terp pearls, which keep the oil moving for even, complete vaporization.
