Our Quartz Whirlwind Disc Carb Cap is an essential tool to help you get the most from your concentrates, especially with terp pearls.

This "whirlwind" effect efficiently spins your terp pearls, distributing heat and material for dense, flavorful vapor every time.
We crafted this cap from 100% durable quartz with a frosted finish for a secure grip, building it for performance. Its universal design makes it a versatile addition to your collection, as it is compatible with a wide range of flat top quartz bangers.
Understanding the technical details shows why this carb cap performs so well. Here's a breakdown of its features and the benefits you get.

Choosing the right carb cap is important for a great session. Here is what makes our Whirlwind Disc a top choice.
Let's look at the two key features that set this carb cap apart: its unique airflow and its versatile fit.
The "whirlwind" effect comes from several air channels drilled into the disc at an angle. When you inhale, air is pulled through these channels, creating a spinning vortex inside the banger. This cyclone of air is strong enough to make terp pearls spin automatically, churning your concentrate and spreading it across the heated surface for an even and complete vaporization.
This carb cap is designed for nearly universal compatibility with flat top bangers. With its 40mm diameter, it will form a perfect seal on any flat top banger with an outer diameter of 35mm or less. This includes the industry's most popular sizes, like 25mm and 30mm bangers, making it a reliable and versatile choice for most setups.
Follow these six steps to get the best performance from your new spinner cap, especially when you are using it with terp pearls.
Not sure which carb cap style is right for you? Here's how our Whirlwind Disc compares to other popular options we offer.
| Carb Cap | Primary Function | Best For | Material |
|---|---|---|---|
| Quartz Whirlwind Disc (This Product) | Automatic Pearl Spinning (Vortex) | Hands-free, even heating with terp pearls | 100% Quartz |
| Quartz Honey Hive Bubble Cap | Manual 360° Airflow Control | Moving oil around in bucket-style bangers | 100% Quartz |
| Honey Drip Directional Carb Cap | Manual Airflow Control | Targeting specific spots in the banger | 100% Quartz |

Proper cleaning will keep your new quartz carb cap performing like new and ensure the flavor of your dabs stays pure.
For regular cleaning, wipe the cap with a cotton swab dipped in isopropyl alcohol (ISO) after each session while it's still warm, not hot. For a deep clean, you can submerge the completely cooled cap in an ISO bath for 15-30 minutes. Use a pipe cleaner to gently clear any residue from the airflow holes. Rinse it well with warm water and let it air dry completely before you use it again.
Get the most from your new carb cap with these essential accessories. The right banger and pearls will guarantee a perfect session.

You got questions. We got answers
Yes. Our THCa products are hemp-derived and contain less than 0.3% Delta-9 THC by dry weight, which makes them federally legal under the 2018 Farm Bill. Individual state laws vary, so always check your own state before ordering.
Yes. THCa is the non-intoxicating precursor to THC, but when you heat it by smoking or vaping it converts into THC. Expect effects similar to traditional cannabis, including euphoria, relaxation and appetite stimulation.
Orders ship from our US warehouse via USPS and typically arrive within 2 to 5 business days. You receive tracking as soon as your order leaves the facility, and shipping is free on orders over $100.
THCA flower (tetrahydrocannabinolic acid) is cannabis that has high
levels of THCA, a natural compound found in raw cannabis buds.
When heated, THCA converts into THC, the main compound in cannabis that causes a psychoactive high.
With THCa Flower you get the cannabis experience which we all know and love shipped discreetly to your door.
Every batch is third-party lab tested for potency, pesticides, heavy metals and mold. We publish the certificates of analysis on our lab results page, so you can verify exactly what you are buying before it arrives.
Yes. THCa flower can be shipped within the United States because it is classified as legal hemp at under 0.3% Delta-9 THC. A small number of states have additional restrictions, which we follow at checkout.
You must be 21 or older to purchase. We verify age at checkout and require a valid government-issued ID, and an adult signature may be requested on delivery.
Yes, THCa flower can show up on a drug test. Most drug tests look for THC metabolites, and since THCa turns into THC when heated, it can result in a positive test. If you’re subject to drug testing, it’s best to avoid cannabis products that contain THCa.
