The 2" Color Spiral Bubble Carb Cap is a compact glass carb cap built for dabbers who care about both flavor and style. It’s ideal if you’re running quartz bangers and want better airflow control without dealing with bulky glass. At about 2 inches (51mm) across, it’s sized to sit comfortably on most standard bucket-style bangers while you chase smooth, efficient hits.
Key Benefits
- Stronger flavor from every dab — Bubble shape lets you angle and spin the cap so airflow hits your puddle instead of just the rim.
- More mileage from your concentrates — Focused airflow keeps vapor moving across the surface, helping you finish off leftovers instead of wasting them.
- Comfortable, one-hand control — Rounded bubble body gives you a solid grip, even when things get a little sticky mid-sesh.
- Eye-catching spiral design — Color spiral pattern pops on any rig and actually makes it easy to spot on a cluttered coffee table.
- Plays nice with most quartz bangers — The 2 inch (51mm) diameter works well with common bucket sizes, so you don’t have to overhaul your whole setup.
- Built for daily use — Sturdy glass construction stands up to regular heating and cooling when you’re dabbing all week.
Best for
This bubble carb cap is made for dabbers who already have a solid rig and banger and just want their setup to hit better without getting complicated. If you’re the type who likes to run slower, flavorful pulls instead of scorching your concentrates, this cap will feel right at home on your favorite rig. It also pairs nicely with silicone rigs from our silicone bongs & rigs collection if you like durable, travel-ready setups.
How to use it
Once your banger is hot and you’ve dropped in your concentrate, place the 2" Color Spiral Bubble Carb Cap over the top of the bucket and start drawing. Use your fingers to gently tilt and rotate the bubble so the airflow pushes the puddle around the bottom of the banger, helping it vaporize evenly instead of sitting in one spot.
You’ll feel the difference in resistance as you move the cap around; more tilt usually means more direction and movement inside the banger. On flat-top quartz buckets, you can give it a light spin to create that swirling effect people chase, especially if you like using pearls or inserts. For a cleaner setup, park your rig on a nonstick dab mat so you’re not setting sticky caps straight on the table.
When you’re done with the dab, let the cap cool on a safe surface. Avoid dropping it onto hard floors or countertops while it’s hot, since glass doesn’t love sudden impacts or temperature shocks.

Fit & compatibility notes
This cap is a great match for common flat-top and bucket-style quartz bangers in the ~20–25mm range. Oversized bangers may still work but won’t feel as snug, and tiny micro bangers might be overwhelmed by the 2" (51mm) diameter. If your current setup already runs a standard bucket, odds are high this cap will sit and seal nicely.
Because it’s a bubble carb cap, it’s designed to sit on the rim, not lock in like a plug or stopper. That floating fit is what lets you tilt, spin, and steer the airflow where you want it. Combine it with your favorite rig and stash your concentrates in proper concentrate jars to keep your flavors consistent from dab to dab.
Cleaning & care
Let the carb cap cool down fully before handling or cleaning. Once it’s at room temp, wipe off any fresh residue with a cotton swab or cloth. For deeper cleans, soak in isopropyl alcohol, rinse with warm water, and dry completely before putting it back into your rotation.
If you’re tossing this in a travel kit or case, give it a little padding or wrap so you’re not clinking it against heavier gear like metal dab tools, which can chip glass if they knock around together.
Why a bubble carb cap?
Bubble caps took over for a reason: they give you way more control than basic flat caps. The rounded body lets you tilt and angle the airflow so it doesn’t just shoot straight down, it actually chases your puddle around the bottom of the banger. That means better use of your concentrates and fewer half-finished dabs stuck to the corners.
The 2" Color Spiral Bubble Carb Cap keeps that same functionality but adds a bright, swirling look that stands out. It’s the kind of piece you don’t have to hunt for when you’re already a couple dabs in because the colors are easy to spot, especially if you’re working on a cluttered tray loaded with jars, tools, and other accessories.
FAQ
- Will this carb cap fit my banger?
It’s designed to work with most standard quartz bucket bangers, especially in the 20–25mm range. If your banger is way larger or smaller than that, it may not seal as well. A quick way to check is to measure the outside diameter of your bucket and compare it to the 2" (51mm) cap size.
- Does it work with thermal or reactor-style bangers?
Yes, in most cases. As long as your thermal or reactor-style banger has a flat top and a bucket opening that isn’t huge compared to the cap, you’ll still get solid airflow control. Just keep in mind this is a standard bubble cap, not a directional spinner specifically built for terp pearls.
- Is each color spiral pattern the same?
No, that’s part of the fun. The overall style is the same, but because of how colored glass is worked, swirl placement and color emphasis can vary slightly from piece to piece. If you like unique-looking glass, that little bit of variation is a bonus.
- How thick is the glass — is it fragile?
It’s sturdy enough for daily dabbing, but it’s still glass, so try not to drop it onto tile or concrete. Treat it like you do your rig or banger — set it down gently and don’t blast it with water when it’s hot to avoid thermal shock. For a safer landing spot, keep it on your rig tray or a soft storage & packaging insert when you’re not using it.
- How do I clean off dark, baked-on residue?
Let the carb cap cool fully, then soak it in isopropyl alcohol for a bit to loosen the buildup. After soaking, rinse with warm water and wipe away any remaining residue. Repeat if needed, then dry before using again.
- Can I use this on an e-rig or electronic banger?
If your e-rig or electronic banger has a bucket-style top similar in size to a traditional quartz banger, this cap can work just fine. Some proprietary systems have odd shapes or built-in caps, though, so if your device is very specialized, double-check the top opening before expecting a perfect fit.
- Is this a good first carb cap for a new dab setup?
Yes. The bubble style is easy to use, forgiving, and works with most basic quartz buckets, so it’s a solid first cap if you’re building your kit. Pair it with a simple rig from our general smoke shop products lineup and you’ll have a reliable daily driver setup without overcomplicating anything.
