2″ CARVED SPINNER DISC CARB CAP

The 2" Carved Spinner Disc Carb Cap is a clear glass cap designed for dabbers who want better vapor production and airflow control without overcomplicating their setup. The carved disc design creates directional airflow that spins terp pearls and moves concentrate around your banger, so you get more even vaporization and less wasted material sitting in puddles.

Key benefits

• Spin your terp pearls without chasing them — the carved disc creates natural vortex airflow that keeps pearls moving
• Clear glass lets you watch your dab vaporize — no guessing when to stop heating or if you're burning off terpenes
• 2-inch diameter fits most standard flat-top bangers — works with the gear you probably already own
• Simple disc design means fewer places for reclaim to hide — easier cleanup between sessions
• Lightweight glass construction stays cool to the touch on the handle side while trapping heat where it matters

Best for

This cap works well for dabbers running terp pearls who want consistent spin without paying premium prices. It's a solid choice if you're building out a new rig setup or need a backup cap for your rotation. The clear glass appeals to people who like watching their concentrates work — you can see exactly when vapor production drops off and know when your dab is done.

If you're someone who takes multiple dabs in a session, the easy-clean disc design means you're not spending half your sesh scraping out reclaim from complicated cap geometries.

How spinner caps work

Spinner carb caps use angled or carved channels to direct airflow at an angle across your banger's floor. When you inhale, air enters through the cap and spirals around the inside of your quartz banger, creating a vortex effect. Drop in a couple of terp pearls and they'll spin through your concentrate, spreading it across more heated surface area.

The result? More vapor per dab, better flavor, and less of that annoying puddle that sits in one spot and either burns or gets left behind. The carved pattern on this disc cap does the work — you just need to position it and draw.

For best results, use this cap with flat-top bangers rather than angled or beveled styles. The flat seal lets the cap create proper restriction for the vortex effect. Pair it with a silicone dab mat underneath your rig to keep your station organized and catch any stray drips.

Specifications

Fit and compatibility

The 2-inch diameter works with most standard flat-top bangers you'll find on the market. It's designed to rest on top of the banger rather than insert into it, so the main thing you're looking for is a flat sealing surface.

This cap plays nice with 25mm and 30mm diameter bangers — basically anything in the common range for dab rigs. If you're running a smaller 20mm banger or something oversized like a 35mm, you might want to measure first. The disc needs to fully cover the opening to create the restriction that makes the spinner effect work.

One note: this style works best with terp pearls. Without pearls, you still get improved heat retention and some airflow direction, but you're not getting the full benefit of the spinner design. Grab a couple of 6mm pearls if you don't have any — they're the most common size and work with most setups.

Care and cleaning

Let the cap cool completely after your session, then wipe off any residue with a dry cloth. For deeper cleaning, soak in isopropyl alcohol for a few minutes, rinse with warm water, and let it dry before your next use. The simple disc shape means no hidden corners where reclaim builds up.

Frequently asked questions

Will this fit my banger?

If you have a flat-top banger in the 25-30mm diameter range, this cap should work. It's a universal-style disc that rests on top of the banger rather than inserting into it. Measure your banger's outer diameter at the top — if it's under 2 inches, you're good.

Do I need terp pearls for this to work?

The spinner design is optimized for terp pearls, but the cap still functions without them. You'll get heat retention and some airflow direction, but the spinning effect that spreads your concentrate requires pearls to really shine. Most dabbers running spinner caps grab a few 6mm quartz or ruby pearls to complete the setup.

How do I clean reclaim out of the carved pattern?

The carved grooves are shallow enough that a quick iso soak handles most buildup. Dunk it in 91% or higher isopropyl alcohol for 5-10 minutes, give it a gentle swirl, and rinse. For stubborn spots, a cotton swab dipped in iso reaches the carved areas. Store your cap on a dab tool holder or clean surface between sessions to avoid picking up dust.

Clear glass or colored — does it matter?

Functionally, no difference. Clear glass lets you see your vapor production and watch the pearls spin, which some dabbers prefer for dialing in their technique. Colored caps hide reclaim buildup better if you're not cleaning after every session. This one's clear, so you get the full view.

Is glass more fragile than other cap materials?

Glass caps can break if dropped on hard surfaces — that's the tradeoff for heat resistance and easy cleaning. They handle normal dab temperatures without issue and won't off-gas like some cheaper materials. Just set it down gently and don't leave it balanced on the edge of your rig. A silicone dab mat gives you a soft landing zone if you're prone to fumbling.

What's the difference between spinner caps and directional caps?

Spinner caps create a vortex effect to spin terp pearls and spread concentrate across your banger floor. Directional caps have a pointed air channel you can aim at specific spots — useful for pushing puddles around manually. Spinner caps are more set-it-and-forget-it, while directional caps give you more hands-on control. This carved disc is a spinner style.

Can I use this with a nectar collector?

No — carb caps are designed for bangers and nails where concentrate sits in a dish. Nectar collectors work by touching the heated tip directly to your concentrate, so there's no chamber to cap. Carb caps are for rig setups specifically.
