The 2" Wigwag Funnel Carb Cap is a handmade glass carb cap built for dabbers who want real airflow control without sacrificing style. At 2 inches (51mm) across, it covers most standard flat-top bangers and gives you the directional flow you need to chase every last bit of concentrate around the dish. The multi-color wigwag pattern isn't just eye candy—it makes this thing impossible to lose on a cluttered dab station.
This cap is for dabbers running daily sessions who want function first and a little visual flair second. If you've got a small to mid-size rig with a standard flat-top banger and you're tired of generic clear caps that disappear the moment you set them down, this one makes sense. It's especially good for people who keep their setup on a dedicated dab mat and want their accessories to look intentional, not like random pieces thrown together.
Heat your banger to your preferred temp—low-temp dabbers usually aim for that 450-550°F range where you get flavor without scorching. Drop your concentrate, then set the Wigwag Funnel Carb Cap on top. The funnel profile directs air downward toward the base of the banger, which keeps your oil circulating instead of pooling in one spot.
Here's where it gets hands-on: tilt the cap slightly to create directional airflow across the surface. This sweeps concentrate toward the center and up the walls, giving you consistent vapor production through the whole dab. You can also spin it gently to change the direction of flow. Because it's clear glass with those colored lines, you can actually watch how the vapor behaves and adjust your technique on the fly.
After your hit, lift the cap and let it rest on a heat-safe surface. A silicone tray or the corner of your dab mat works well. Don't just drop it on bare wood or glass—thermal shock is real, and so is the sad sound of cracked glass.
For cleanup, let it cool completely first. Wipe off surface residue with a dry cloth or paper towel. When things get gunky, drop it in isopropyl alcohol for 10-20 minutes, rinse with warm water, and dry before your next session. Regular quick wipes keep the wigwag colors bright and prevent buildup from getting baked on.
Some dabbers grab silicone caps for durability, and that's fair. But glass gives you something silicone can't: visibility. You see exactly how your vapor moves, how the puddle behaves, when to adjust your angle. It's the difference between driving with clear windows versus a foggy windshield.
Glass also doesn't hold onto flavors between sessions the way porous materials can. If you're rotating through different strains or concentrates, you're not getting ghost notes from last week's rosin sneaking into today's live resin. According to Leafly's guide to dabbing, maintaining clean equipment is one of the simplest ways to preserve the terpene profile of quality concentrates.
The wigwag pattern serves a practical purpose beyond aesthetics. Those raised color lines give you better grip when you're handling a warm cap, and the bold pattern makes it stand out against clutter. Plain clear caps blend into everything. This one doesn't.
| Type | Funnel carb cap |
|---|---|
| Material | Glass |
| Diameter | 2 inches (51mm) |
| Design | Multi-color wigwag (pattern varies by piece) |
| Compatibility | Flat-top quartz bangers up to 2" outer diameter |
This cap is sized for standard flat-top quartz bangers with an outer diameter at or under 2 inches (51mm). That covers most of what you'll find in the typical dab setup—your everyday flat-tops, standard slurpers, and most terp slurpers that use a flat cap.
It won't seal perfectly on oversized bangers or heavily sculpted specialty nails. If your banger has a flared rim wider than the cap itself, air will leak around the edges and you'll lose that controlled restriction. For standard gear, though, it sits flush and does exactly what it's supposed to do.
Weight-wise, it's light enough that it won't tip smaller rigs or feel awkward on compact setups. Works well with travel rigs, daily drivers, and full-size pieces alike. If you're building out a complete station, it pairs well with concentrate jars that match the heady aesthetic.
