Bought this cap for my infinity mini rig. Love the four air holes. Really provides maximum airflow. Hits better than this heady cap I got from a Pendy melt worf $70. Would immediately replace if anything were to happen to this one. Easy to clean, I just dunk/bath it in iso. Thanks MJA

It works flawlessly. Fits the mini figs like a charm.

Aaron 5/5

MJA Spinner Carb Cap

Wow what a cap! I was looking for a cap that would fit some of the other smaller bangers I have and it works great. The bottom part will fit into a banger with a ⅜" or larger opening, with the bubble being around ¾". (These are approximate measurements.) But if you pair it with a MJA Deep Round Bottom Cold Start banger you won't want another banger... js Perfect pair, great cap🔥💨💨

Works great 👍 . I should have bought this one first. I bought the Champagne spinner cap it works so so. But this spins glass and quartz.

MJA Spinner Carb Cap

It really creates a concentrated air vortex which spins your pearls. Two pearls recommended for effect. Got this as part of a $150 MJA Mystery box, most functional piece of glass I’ve EVER purchased. All the reviews are right, you ain’t dabbing until you get this. Running this on a stock Gemini (orbital series) rig with stock banger.

If you own a mini rig from MJ arsenal, this spinner cap is pretty much an essential to have. I use to have the directional carb cap, and didn't expect much of a difference. I was wrong. I love this little guy and its made a big difference in my experience. I would 10/10 recommend.

Bought this delivered on time, didn’t like at first but after using it for a while it’s one of my favorite caps for sure. Quieter than the mj flat cap. Feels as if airflow was slightly restricted at first but good smoke production

The MJA Spinner Carb Cap gets your pearls spinning with ease. It’s the perfect dab carb cap upgrade for a smoother hit and an elite smoking experience.

Spinner Carb Cap FAQs

What is a spinner carb cap, and how does it work?

A carb cap works to retain heat within the banger. This optimal vaporization of concentrates lets you enjoy your hit at lower temperatures without sacrificing flavor.

A spinning carb cap creates even more airflow than a standard cap. As the name suggests, spinner caps create a spinning motion within the banger, rotating pearls and moving oil to ensure even vaporization. It is an essential accessory for any smoker looking for fuller hits without the manual effort required from bubble carb caps.

Is this a good carb cap for terp pearls?

Yes, this is an excellent carb cap for terp pearls! 

This spinning carb cap features a 4-hole directional air flow design, creating a consistent vortex inside your banger. This keeps your terp pearls moving, spreading your concentrate across the heated surface to prevent pooling, reduce waste, and improve convection inside the banger. 

The result? Better flavor and fuller hits without overheating your setup.

Is a spinner carb cap better than a standard carb cap?

In most setups, a spinner carb cap is an amazing upgrade from a standard carb cap.

A standard carb cap traps heat, restricting airflow to concentrate vapor and prevent it from burning off too quickly. However, airflow is still pretty basic, and oil can sit in one spot, creating hotspots and uneven vaporization. 

A spinner cap turns as you inhale, creating a vortex within your banger to allow for even airflow, better heat retention, and more even vaporization. This helps you get the most out of your concentrate (we’re talking flavor and lasting power).

Is a spinner carb cap better than a bubble carb cap?

It depends on what type of smoking experience you want to have. Each type of carb cap offers different benefits for your setup.

A bubble carb cap gives you manual control. The cap is tilted and angled to direct airflow across the banger. A bit of technique is required when using a bubble carb cap to create consistent airflow, and you may find it trickier to master at first.

A spinner carb cap automatically provides airflow. The holes in the cap’s design create a vortex in your banger as you inhale. If using terp pearls, this airflow spins them and moves your concentrate around for consistent vaporization.

If you like more personalized control, the bubble carb cap might be more your style. If you want more of a hands-off experience, a spinner cap could be the carb cap for you (it never hurts to experiment with both).

What size banger does this spinner carb cap fit?

This spinning cap measures 1.5in x 0.75in and is designed to fit a banger with a similar diameter. For best results, use with a flat top banger (not angled or beveled) to create a seal and maintain consistent airflow that keeps your pearls spinning.

How do you use a spinner carb cap?

Using a spinning cap is simple. Start by heating your banger as you normally would. Once it has cooled to your preferred temperature, add your concentrate. Then place the spinner carb cap on top of your banger. As you take slow, steady inhales, the spinner cap will turn, creating a vortex of air that helps your concentrate vaporize evenly. If using terp pearls, the spinner cap will automatically spin them as you inhale.

Is this a good carb cap for quartz bangers?

Yes, this spinner is a great carb cap for quartz bangers. Quartz works best when heat and airflow are balanced, and this cap provides the perfect solution. 

Because quartz heats and cools quickly, maintaining the right temperature in a quartz banger makes a noticeable difference. The 4-directional carb holes of this cap promote circular airflow, distributing oil evenly and retaining heat longer. This leads to better low-temp dabs, reduced hot spots and waste, and smoother, more consistent pulls.
