2″ Dichro Spiral Bubble Carb Cap

The 2″ Dichro Spiral Bubble Carb Cap is a glass carb cap for dabbers who want actual control over their hits, not just something to cover the banger. The bubble shape lets you tilt and spin to direct airflow exactly where you want it, and the dichroic spiral inside the glass catches light in a way that makes every rotation worth watching. At 2 inches (50.8mm), it fits comfortably in hand and caps most standard flat-top bangers without drama.

Why this cap works

• Real airflow control — The bubble design lets you angle and spin to push air where it matters, so your concentrate spreads across the hot surface instead of pooling in one sad corner.
• Less waste, more vapor — Better airflow movement means you're actually using what you put in the banger, not leaving half of it as cold puddle.
• Glass that earns its spot — The dichroic spiral shifts color as you move it. It's not just functional, it's the kind of piece you actually want sitting out on your station.
• Sized for daily use — 2 inches is big enough to grip and spin comfortably, small enough that it doesn't feel clunky or get in the way.
• Built for real sessions — This isn't a shelf piece. It's made to handle regular use without feeling precious about it.

Made for

Dabbers who've moved past the generic cap that came with their first rig and want something that actually improves their hits. If you already have a decent banger and you're wondering why your dabs feel inconsistent, the cap is usually the weak link. This one fixes that. It pairs well with a proper dab mat so you have somewhere safe to set it between hits without worrying about it rolling off the table.

How to use it

Drop your concentrate into a heated banger, then place this cap over the top to seal it. Here's where bubble caps earn their keep: instead of just sitting there, you can tilt the cap to angle the airflow hole, directing air across the bottom of the banger. Gentle spins keep your concentrate moving, spreading it across more hot surface area for even vaporization.

The trick is light, slow movements. You're not trying to tornado the thing — just enough motion to keep the oil from settling in one spot. Watch through the glass and you'll see the vapor respond to how you're moving the cap. When you find the angle that produces thick, smooth pulls, you'll feel the difference immediately compared to a basic flat cap that just plugs the hole.

Between dabs, set it on a heat-safe surface or next to your dab tools so it's ready for the next round. The dichro spiral looks especially good under lamp light, if you're the type who appreciates that sort of thing.

Specifications

Compatibility notes

This cap works with most standard flat-top bangers. If your banger has a reasonably sized opening — not a tiny terp slurper or an oversized bucket — the 2-inch diameter should sit and spin comfortably. Beveled edges are fine. Most daily driver setups from common brands will match up without issue.

If you're running a specialty banger with unusual dimensions, measure the opening first. But for the vast majority of rigs people actually use, this is a drop-in upgrade. It also plays nice with setups from our smoke shop collection if you're building out a complete station.

What makes bubble caps different

Flat caps and simple directional caps work by restricting airflow. They're better than nothing, but they don't give you much control. Bubble caps change the game because the rounded shape lets you tilt in any direction, steering air across the banger floor instead of just letting it fall straight down.

That control translates to practical benefits. Your concentrate spreads out instead of pooling. More surface contact with the hot glass means more even vaporization. You get better flavor from low-temp dabs because you're not cooking one spot while the rest stays cold. And you waste less product — that leftover puddle at the bottom of the banger shrinks noticeably when you're actually moving your concentrate around.

The dichro spiral adds visual feedback too. You can see the color shift as you spin, which is weirdly satisfying when you're a few dabs deep and just want things to look interesting. It's not just decoration — it gives you something to watch while you dial in your technique.

Care and cleaning

Let it cool completely before cleaning. For light residue after a session, a quick wipe with a cloth or cotton swab handles it. For heavier buildup, soak in isopropyl alcohol, rinse with warm water, and dry fully before your next use. Skip the abrasive scrubbers — they'll scratch the glass.

FAQ

• Will this fit my banger?
  Probably. It's sized for standard flat-top bangers, which covers most of what people actually use. If your banger opening is close to 2 inches and has a flat or slightly beveled top, you're good. Specialty bangers with unusual dimensions might be hit or miss — measure if you're unsure.
• Does the dichro color fade or chip off?
  No. The dichroic effect is fused inside the glass, not a coating on the surface. Normal use and cleaning won't affect it. You'd have to physically break the glass to damage the color.
• How do I clean this without scratching it?
  Cool it down first. Wipe fresh residue with a soft cloth or cotton swab. For stubborn buildup, soak in isopropyl alcohol for 15-30 minutes, then rinse with warm water. Avoid abrasive pads or brushes. If you're cleaning your other gear at the same time, this can go in the same iso bath as your quartz banger.
• Is this too nice to use every day?
  It looks nice, but it's built for regular use. The size, weight, and glass thickness are all designed for daily sessions. It's not a display piece that you're afraid to touch.
• What's the actual advantage over a basic cap?
  Control. Basic caps just plug the hole. Bubble caps let you direct airflow, which spreads your concentrate across more hot surface, improves vaporization, and reduces waste. You'll notice the difference in how smooth your hits feel and how little product gets left behind.
• How fragile is it?
  It's glass, so don't drop it on hard surfaces. But it's not delicate crystal either. Normal handling, setting it down between dabs, cleaning it — all fine. Just give it a soft landing spot. A silicone dab pad works well for this.
• Do I need anything else to use this?
  Just a compatible banger and a rig. If you're starting from scratch, grab a quality banger first, then add this cap. It's the kind of upgrade that makes your existing setup work better rather than requiring new gear.
