1.5″ DICHRO DIRECTIONAL CARB CAP

The 1.5" Dichro Directional Carb Cap from What You Need is a compact glass carb cap built for dabbers who care about flavor, efficiency, and a little bit of sparkle on the table. At just 1.5 inches (38mm), it’s small enough to feel natural in hand but big enough to fully cover most standard flat-top bangers and domeless nails. The real win here is the directional airflow design, which helps spin and move your oil so you’re not leaving precious concentrate stuck in the corners.

Why It Works

• Better flavor from the same amount of oil — Directional airflow keeps your puddle moving, so more of your concentrate actually vaporizes instead of burning on one hot spot.
• Stretch your dabs further — By trapping heat and airflow over the nail, this cap helps you clear more vapor from each pull instead of watching it disappear into the room.
• Comfortable, compact control — The 1.5 inch (38mm) size feels natural to spin and tip, giving you easy control without feeling bulky or awkward.
• Clean, consistent function — Simple glass construction with a focused air path means less to go wrong and a predictable draw every time.
• Dichro that actually pops — The shimmering dichroic finish catches light from every angle, so it looks as good on the shelf as it does mid-sesh.
• Plays nice with most rigs — Works with a wide range of domeless nails and flat-top bangers, so you don’t have to rebuild your whole setup around one cap.

Best For

This carb cap is made for dabbers who are already comfortable with their rig and just want smoother, tastier pulls without overcomplicating things. If you’ve got a favorite banger on your daily driver and want a cap that actually does something (not just sit there), this fits right in. It’s also a nice upgrade for anyone who’s been using a basic bubble cap and wants to try true directional airflow without jumping into specialty spinners or marbles. If you’re dialing in your whole station, pairing it with a nonstick dab mat keeps sticky tools and caps from messing up your table.

How to Use It

Once your banger or nail is hot and you’ve dropped in your concentrate, set the cap over the top and start to gently twist or tilt it to guide airflow. The directional design pulls air across the surface of the oil, helping your puddle travel around the bottom of the banger instead of pooling and burning in one spot. You’ll notice the vapor feels smoother and your dab clears more evenly when you keep the airflow moving.

The cap is small enough that it’s easy to control with just fingertips, even when you’re a few dabs deep and want something simple that just works. When you’re done, let it cool on your rig stand or stash it with your other dab accessories so it’s not rolling off the coffee table.

For cleaning, let the glass cool completely, then wipe off any residue. For a deeper refresh, a quick soak in isopropyl alcohol followed by a rinse and dry will keep the dichro shine looking new. If you keep your concentrates stored in proper concentrate jars, you’ll also cut down on crusty buildup and keep your cap from getting sticky between seshes.

Specifications

Fit & Compatibility

This cap is designed for most standard flat-top bangers and domeless nails with a similar opening size to its 1.5 inch (38mm) profile. It’s not built to lock onto any one brand specifically, but rather to cover and control airflow over typical quartz bangers and glass nails you’d find on everyday rigs. If your banger is very oversized, unusually shaped, or heavily beveled, you may not get a perfect seal, but directional caps don’t require a vacuum-tight fit to work well.

Think of it as a reliable, all-around cap for your regular rig rather than something ultra-specialized. If you’re running a compact rig or one of our more rugged silicone bongs and rigs with a standard banger, this cap will feel right at home as your daily driver.

FAQ

• Will this carb cap fit my banger?
  It’s made to work with most standard flat-top quartz bangers and domeless glass nails that have an opening around the size of the cap. As long as your banger isn’t extra-wide or a super odd shape, you should get solid coverage and good directional airflow.
• Is this a directional or a regular bubble cap?
  This is a directional carb cap, which means it’s shaped to guide airflow across the bottom of your nail rather than just capping it. When you twist or tilt it, it pushes air around the puddle to help vaporize more of your concentrate. If you’re used to a simple bubble cap, you’ll notice better movement and more even vapor production.
• How do I clean the dichro finish without damaging it?
  Let the cap cool, then wipe off any fresh residue with a dry or slightly damp cloth. For heavier buildup, soak it in isopropyl alcohol, rinse with water, and let it dry fully before using again. The dichro is in the glass itself, so normal cleaning won’t hurt it.
• Does the color or dichro change how it hits?
  No, the color and dichroic shine are purely for looks. The way it hits comes from the shape and directional airflow, not the color. Pick the color that matches your rig or mood — the function stays the same.
• Can I use this with an e-rig or electronic nail?
  If your e-nail uses a standard-style banger or domeless nail with an open top similar in size to traditional setups, this cap will usually work fine. Some all-in-one e-rigs have proprietary shapes or built-in caps, though, so check that your setup actually has a place for a separate carb cap before grabbing one. If your electronic setup ever feels limiting, you can always run a classic rig with quartz and use this alongside one of our durable smoke shop essentials.
• Is glass a good material for carb caps?
  For most dabbers, yes. Glass gives you a clean flavor, is easy to see through so you can watch your puddle, and it’s simple to clean. As long as you avoid dropping it on hard floors or hitting it against your nail while it’s hot, a glass carb cap like this can last a long time.
• What else do I need to get the most out of this carb cap?
  You’ll want a good-quality banger, a rig with solid function, and a clean space to work. Running your setup over a nonstick pad or parchment surface helps keep sticky spills contained, and if you’re handling your own material at home, having proper parchment paper on hand makes loading and storing your dabs a lot easier.
