2″ TWO-TONE BUBBLE TRAP CARB CAP

The 2″ Two-Tone Bubble Trap Carb Cap is a compact glass carb cap built for dabbers who want tighter airflow control and better flavor from every pull. At around 2 inches (50.8mm), it’s small, easy to handle, and made to sit comfortably on most flat-top bangers. The bubble trap design inside the glass doesn’t just look dope—it helps smooth and direct airflow so your concentrates don’t go to waste.

Why You’ll Actually Use This Cap Every Day

• Stronger, tastier pulls — Bubble trap airflow helps keep vapor moving over your oil instead of stalling, so you taste more terps from the same dab.
• Real control over your hit — The spade-style top makes it easy to turn, lift, and feather airflow while you’re mid-sesh.
• Less pooling, more vapor — Consistent airflow helps keep concentrates from just puddling in the bottom of your banger.
• Looks as good as it hits — Two-tone glass with trapped bubbles adds a custom, heady vibe to your setup without the custom-glass price tag.
• Comfortable in the hand — The 2″ (50.8mm) height and shape are easy to grab and spin, even when things get a little sticky.
• Plays nice with most bangers — Designed to work with common flat-top bangers so you don’t have to re-buy core hardware just to upgrade your cap.

Best For

This cap is made for dabbers who already have their rig and banger dialed in but want better control without getting into super technical spinner setups. If your daily driver lives on a dedicated dab mat and you care about flavor as much as clouds, this is the kind of small upgrade you’ll feel right away.

How to Use It

Once your banger is hot and your dab is in play, set the 2″ Two-Tone Bubble Trap Carb Cap over the top of the banger to restrict airflow and build a bit of internal pressure in the rig. As you pull, you can slightly lift or angle the cap to fine-tune how much air you’re letting in, which affects how quickly your concentrate vaporizes and how dense the vapor feels.

The spade-style top gives you a solid grip so you can comfortably twist or rock the cap while you inhale, helping push vapor around and keep the oil moving. Pair it with a solid flat-top banger and your favorite dab tools, and you’ll notice smoother, more efficient dabs without changing the rest of your setup.

Between hits, you can park the cap on a stand, lay it on a heat-safe surface, or keep it next to your rig on a nonstick pad. If you’re already using heavy-bottom concentrate jars for your extracts, this cap fits right into that “buy it once, use it forever” mindset—simple, durable glass that just works.

Specifications

Fit & Compatibility

This carb cap is designed as a general fit option for standard flat-top bangers—especially medium-size ones that most dabbers use for daily rigs. Because it’s glass and not a tight cork-style plug, it sits on top and lets you manually control the seal and angle rather than locking into one fixed position.

If you’re running a full silicone setup, this cap still plays nicely with glass bangers that drop into silicone bongs and rigs, giving you the heat resistance of glass where it matters and the durability of silicone everywhere else.

Cleaning & Care

Let the carb cap cool completely before touching it for cleanup. Once it’s safe to handle, wipe off any visible residue with a cloth or cotton swab. For a deeper clean, soak the cap in isopropyl alcohol, rinse with warm water, and let it dry fully before the next sesh.

FAQ

• Will this carb cap fit my banger?
  It’s made to work with most standard flat-top bangers in that medium “everyday” size range. Because it sits on top instead of plugging in, you get a little flexibility—if your banger isn’t tiny or oversized, this cap should do the job.
• Is this directional or just a regular cap?
  This is more of a standard bubble-style cap with a bubble trap design in the glass. You get control by tilting, rocking, and lifting the cap to change airflow, rather than having built-in spinning channels like a dedicated directional or spinner cap.
• What’s the point of the bubble trap design?
  Bubble trap refers to the glasswork style—little “trapped” air bubbles inside the colored glass. Functionally, you get a bit more texture and grip plus a thicker feel in the hand, and visually it just looks way better than plain clear glass.
• Is the borosilicate glass durable enough for daily dabs?
  Yes. Borosilicate is the same kind of glass used for quality rigs and lab glass. Treat it like any other glass accessory—don’t drop it on tile—and it’ll handle regular heat and cooldown cycles just fine. If you want to keep the rest of your setup tough too, pairing it with unbreakable silicone pieces is a smart move.
• How do I keep it from getting sticky and crusty?
  Try not to drag the cap directly through puddles of concentrate, and give it a quick wipe after your sesh while any residue is still soft. When it does build up, a short soak in isopropyl alcohol brings it back to clean glass.
• Does the two-tone color affect performance at all?
  No—color is purely aesthetic. The two-tone and bubble trap work are all done in borosilicate, so it performs just like clear glass, it just looks way better on the table.
• What else do I need to use with this carb cap?
  You’ll want a rig, a flat-top banger, and a good dab tool at minimum. If you’re dialing in a full dabbing station, adding things like PTFE or parchment for handling concentrates and stash-ready storage and packaging makes the whole setup smoother and way less messy.
