Carb Caps

If you're dabbing without a carb cap, you're leaving terpenes - and money - on the table. A carb cap for your dab rig is one of the simplest, highest-impact upgrades you can make to your setup. Whether you're running a classic banger, a thermal flat top, or a premium e-rig, the right carb cap transforms your session from wasteful to world-class.

At SmokeDay, we carry carb caps for every style, every banger, and every budget - so you can lock in flavor and get the most from every dab.

What Is a Carb Cap & How Does It Work?

A carb cap is a small cover placed over the opening of your banger or nail immediately after you load your concentrate. By restricting airflow, the carb cap creates a low-pressure environment - essentially a vacuum - inside the banger. That drop in air pressure lowers the boiling point of your concentrate, meaning you can dab at lower temperatures without the oil pooling or going to waste.

Dabbing with a carb cap vs. without one:

With a carb cap: Lower temps, fuller vaporization, rich flavor, zero puddles. Your terpenes stay intact.
Without a carb cap: Higher temps needed to vaporize, harsher hits, burnt taste, and concentrate residue left behind.

Bottom line - if you care about flavor and efficiency, a dab carb cap isn't optional. It's essential.Types of Carb Caps We Carry

Not all carb caps work the same way. Different styles create different airflow patterns, which changes how your concentrate moves and vaporizes. Here's a breakdown:

Bubble Carb Cap

The classic. A bubble carb cap features a rounded, dome-shaped body with a stem you spin between your fingers to redirect airflow inside the banger. That spinning motion swirls the melt around the walls, ensuring full coverage and even vaporization. Great all-around choice, especially with flat-top bangers.

Spinner / Directional Carb Cap

A spinner carb cap (also called a directional airflow carb cap) has an angled or offset airhole that sends air in a circular direction as you inhale. This creates a natural spin inside the banger - no finger-twisting required. It's the go-to pairing for terp pearls, since the directional airflow keeps the pearls in constant motion, maximizing concentrate contact and vapor production.

Vortex Carb Cap

A step up from standard directional caps, the vortex carb cap is engineered to generate a tight, cyclonic airflow pattern. The result is aggressive pearl spin and exceptional melt coverage - ideal for experienced dabbers chasing maximum efficiency on each session.

Directional Carb Cap (Straight-Neck Style)

A straightforward take on directional airflow, these caps have a fixed angled hole that controls where air enters the banger. Simple, effective, and easy to use - a solid pick for everyday dabbing.

Material Options

The material your carb cap is made from affects heat retention, durability, and flavor neutrality.

Glass carb cap - The most popular option. Borosilicate glass is flavor-neutral, easy to clean, and available in dozens of styles. A great all-purpose choice.
Quartz banger carb cap - Quartz retains heat longer than glass and is incredibly flavor-neutral. Often sold as matched sets with quartz bangers for seamless compatibility.
Titanium carb cap - Nearly indestructible. Titanium heats quickly and can handle drops and daily abuse. Slightly less flavor-neutral than quartz or glass, but preferred by durability-first users.
Ceramic carb cap - Excellent heat retention and a clean, neutral flavor profile. Slightly more fragile, but a favorite for flavor chasers.
Silicone carb cap - Practically unbreakable and great for travel setups. Best for function over flavor - silicone can add a slight taste at high temps, so pair with lower-temp sessions.

Buyer's Guide - Finding the Right Fit

Sizing

Carb caps need to cover your banger opening to create a proper seal - but they don't need to be airtight. For most standard flat-top bangers, look for a cap designed for 14mm bangers or check the inner diameter of your banger's opening. If you're using a 10mm or 18mm setup, match accordingly.

Compatibility with E-Rigs

Running an electronic dab rig? Make sure your carb cap is designed for your device:

Puffco Peak / Peak Pro / Proxy - These use proprietary atomizers; use Puffco-compatible caps or the included cap. Aftermarket options are widely available.
Dr. Dabber Switch 2 - Uses a ceramic cup; look for caps designed to fit the Switch's insert diameter.
Focus V Carta 2 - Compatible with standard Carta-style caps or aftermarket options made for the Carta atomizer.

Terp Pearls & Carb Caps

If you're using terp pearls, pair them with a spinner or vortex carb cap. The directional airflow is what keeps the pearls spinning - without it, they just sit there. Most spinner caps work perfectly with 6mm terp pearls in a standard flat-top quartz banger.
