Best carb caps for carta 2 in 2024

June 24, 2025

The Focus V Carta 2 is a popular, high-performance E-Rig with a large 3D ceramic atomizer, glass bubbler, customizable temp settings, and 2000mAh battery, perfect for on-the-go dabbing.

If you’re looking to get the most out of your Focus V Carta 2, then a carb cap is a must-have accessory.

Carb caps are designed to trap and retain heat, modify airflow, and improve convection at lower temperatures. With the right carb cap, you can get the most out of your dabbing experience.

There are many different styles of carb caps available on the market. which one to get? what's the difference between them?

In this article, we’ll explore how to choose the best one for your Focus V Carta 2, and recommend some top options for peak performance.

What Are The Benefits of Carb Caps?

Having the right Carb cap can make all the difference. Carb caps help control airflow and ensure efficient vaporization, enhancing the overall dabbing experience.

There are four main reasons to use a carb cap while you’re dabbing:

1. Control airflow: Direct airflow over the surface of your concentrate, evenly vaporizing it for a smoother hit.

2. Retain Heat: Carb caps trap heat, allowing for lower temperature dabs and preventing your concentrates from burning too quickly.

3. Improve dab taste: By allowing you to dab at lower temperatures, carb caps help preserve the delicate flavors of your concentrate, especially those rich in terpenes.

4. Reduce concentrate waste: By controlling airflow, carb caps prevent concentrates from being wasted due to overheating.

Overall, By limiting the airflow of the dab, you retain heat in the bucket-style aromizer. This lowers the air pressure in your atomizer and increases the thickness of your vapor.

How to Choose the Right Carb Cap for Focus V Carta 2?

When it comes to choosing a carb cap for your Focus V Carta 2, there are four key factors to consider.

1. Compatibility

Essentially any Carb cap will work with the carta 2. they just sit on top of the grommet/atomizer.

If you are not sure or want the best seal or airflow control, you can choose an OEM part designed specifically for this carta 2 rig or verify that third-party caps are compatible.

2.Size

The most important thing to get right is size. If your carb cap doesn’t fit, it’s useless.

The Focus V Carta 2 utilizes a 14mm diameter Intelli-Core atomizer for concentrates, and a 22mm diameter atomizer for dry herb.

Size determines the seal, Make sure the cap locks airtight onto the Intelli‑Core chamber to direct airflow properly.

3. Style

The Focus V Carta 2's atomizer has a Flat-top design, just see what styles of carb caps work with it. Some key design features to look for include:

Directional Airflow: A good carb cap ensures optimal airflow across the atomizer surface, helping the concentrate move and vaporize evenly. Directional caps are particularly effective at swirling the concentrate, ensuring every drop is utilized.

Seal Quality: A tight seal is vital for controlling airflow and maintaining the correct temperature inside the atomizer. Poor seals allow excess air, disrupting the temperature balance and leading to wasted concentrates.

Tether Attachment: Some carb caps come with tethers that prevent you from losing them—a common issue during sessions. The Carta 2 Intelli-Core Bubble Cap is a popular option that includes a silicone tether.

Terp pearls make a difference: If you’re using terp pearls, you’ll want a vortex carb cap. This is the style of carb cap that makes the terp pearl spin.

4. Material

You’ve got a range of materials for carb caps, including Glass, Titanium, Quartz, and Silicone. When in doubt, glass is a great choice.

Glass: Most common for high-end dabbers, glass carb caps offer superior flavor retention. However, quartz can be fragile, especially when dropped, subjected to constant heat and handling.

Titanium: Durable and highly heat-resistant, titanium carb caps can handle higher temperatures, making them suitable for more robust sessions. Titanium heats up faster and retains heat longer, but it may slightly alter the flavor of your vapor.

Quartz: Quartz offers the best heat retention and flavor preservation. It’s also more resistant to thermal shock compared to glass.

Silicone: While not as heat-retentive as glass, Quartz, or titanium, silicone is incredibly durable and easy to clean. It’s often used in hybrid designs to prevent users from misplacing their carb caps during sessions.

Silicone will never break no matter how many times you drop it. It's also the least expensive type of carb cap you can get.

These can yield smoother, more flavorful sessions—just double‑check that they seat snugly in the Carta 2 to maintain that seal.

3. Community’s Favorite: Puffco Peak Pro Ballcap + Flux Cap Adapter

Reddit users frequently recommend using a Puffco Peak Pro ballcap on the Carta, paired with a Flux Cap (e.g. from Tuff Tethers) to get a snug fit.

“Might I suggest a puffco peak pro ballcap...best carb cap I’ve tried yet. They fit nice n snug and work with a carta tether...”
