2″ DICHRO SPIRAL BUBBLE CARB CAP

The 2″ Dichro Spiral Bubble Carb Cap is a glass carb cap built for dabbers who care about both flavor and function. The bubble shape gives you easy airflow control so you can steer your hits instead of just hoping for the best, and the dichro spiral design turns every spin into a little light show. At 2 inches (50.8mm), it’s compact enough for daily use but big enough to comfortably handle and cap most standard bangers.

What You Get

• Dialed-in airflow — Bubble-style design lets you angle and spin the cap to control how much air hits your concentrate for thicker, tastier pulls.
• Smoother, more efficient dabs — Better airflow control means less puddle left in the banger and more vapor where it belongs.
• Showpiece-level glass — The dichroic spiral catches the light and shifts as you move it, so it actually looks as good as it hits.
• Comfortable size in hand — At 2 inches (50.8mm), it’s easy to grip and spin without feeling bulky or fragile.
• Reliable for daily use — Made from quality glass that’s ready for regular seshes, not just something you baby on a shelf.
• Instant upgrade to basic rigs — Even a simple setup feels more dialed-in once you add a proper bubble carb cap.

Best For

This carb cap is made for dabbers who have moved past basic caps and want real control over how their rig hits. If you’re already rocking a favorite banger and just need a nicer cap to complete your setup, this is the kind of small upgrade that makes every sesh feel more intentional. It also pairs nicely with any dedicated dab pad or mat so you’ve got a safe spot to set it down between hits.

How to Use It

Once your banger or nail is ready and you’ve dropped in your concentrate, place the Dichro Spiral Bubble Carb Cap over the top to cover the opening. From there, the magic is in the movement: gently tilt, spin, and swirl the cap to direct airflow and keep your concentrate moving around the hot surface.

The bubble shape gives you a wide range of motion so you can chase every last bit of oil, instead of leaving a cold puddle at the bottom. Light, slow spins usually give the best control — especially if you’re the type who likes to watch the vapor dance inside the banger. When you’re done, set it aside on a heat-safe spot or a nonstick surface along with your other dab tools and dabbers so it’s always within reach for the next sesh.

Specifications

Fit & Compatibility

This 2″ bubble carb cap is designed to play nice with most standard flat-top bangers and nails. If your banger has a reasonably sized opening and a flat or slightly beveled top, odds are good this will sit and spin comfortably on it. Oversized or very tiny specialty bangers may not be ideal, but most common dab rigs and daily drivers will match up just fine.

If you’re building out your whole station, it pairs especially well with sturdy glass or unbreakable setups from our broader smoke shop products collection so your cap isn’t the only upgrade in the mix.

Care & Cleaning

Let the carb cap cool fully before you try to clean it — hot glass and cold liquids don’t mix. For light cleanup, a quick wipe with a cloth or cotton swab will handle light reclaim buildup. For deeper cleans, soak it in isopropyl alcohol, rinse well with warm water, and let it dry completely before your next dab.

If you like keeping everything organized and clean between runs, storing your cap near your concentrates and concentrate jars makes it easy to grab everything in one move.

Why Bubble Caps Hit Different

Compared to flat or simple directional caps, bubble carb caps give you more freedom to move. That freedom translates into better control over where air hits the concentrate, which helps the oil spread out over the surface instead of pooling in one spot. The result is more even vaporization and better use of every drop you put in.

The dichro spiral isn’t just cosmetic either — it adds depth and visual feedback while you’re spinning the cap, which is surprisingly nice when you’re a couple dabs in and just want things to look as good as they feel. If you’ve ever used a plain clear cap and thought, “this works, but it’s boring,” this is the glow-up.

FAQ

• Will this carb cap fit my banger?
  It’s designed to work with most standard flat-top bangers and nails. As long as your banger opening isn’t unusually tiny or massively oversized, the 2″ bubble should sit comfortably and let you spin it for directional airflow. If you’re unsure, compare the banger opening to the 2-inch (50.8mm) size and make sure it has a flat top surface.
• Is the dichro color going to fade or flake off?
  No. The dichroic spiral effect is inside the glass, not a surface sticker or paint. Under normal use and cleaning, the color and sparkle will stay put and keep looking good sesh after sesh.
• How should I clean this without damaging it?
  Let it cool all the way down first, then wipe off any fresh residue with a cloth or cotton swab. For heavier buildup, soak the cap in isopropyl alcohol, rinse thoroughly with warm water, and dry before using again. Keep harsh abrasives away so you don’t scratch the glass. If you’re already cleaning other gear or silicone bongs and rigs, you can usually clean this at the same time.
• Is this okay for everyday use, or is it more of an art piece?
  It looks like an art piece, but it’s absolutely meant to be used. The size and shape are made for real-world, daily dabbing — it just happens to look a lot nicer than the throwaway cap your first rig came with.
• What’s the advantage of a bubble carb cap over a simple cap?
  Bubble caps let you tilt and spin to direct airflow instead of just plugging the banger. That movement helps spread your concentrate across the hot surface and encourages better vaporization, which can mean more flavor, smoother pulls, and less waste sitting in the bottom of the bucket. If you pair it with a good banger and solid dab accessories, it’s a noticeable upgrade.
• Is it fragile?
  It’s still glass, so you don’t want to drop it on tile or smack it off the table, but it’s built for actual use. Treat it like any other nice piece of glass — set it down gently, avoid extreme temperature shocks, and give it a safe landing zone, like a soft parchment-lined area or dab station.
• Do I need any special gear to use this carb cap?
  No special gear required — just a compatible banger or nail and a rig. If you’re building a new setup from scratch, this carb cap drops in easily with most standard dab rigs and makes a good finishing touch once you’ve got your main hardware sorted.
