Carb caps from AFM Glass, One Trick Pony, Str8 Glass, Conversion Glass, Gordo Scientific, JAG, Mothership Glass, Puffco, and 4 Point 0 — over 200 caps spanning bubble caps, directional caps, spinner caps, flat-tops, and terp slurper caps. The cap that traps heat and controls airflow over a quartz banger, sized for every joint and banger format. Stocked at Angies Boutique, 838 N Broadway in Los Angeles.
A carb cap is the small cap placed over a quartz banger after the concentrate is loaded. It does two jobs: it traps heat so the banger stays at vaporizing temperature longer, and it restricts airflow so the concentrate vaporizes evenly at a lower temperature instead of burning off. The result is denser vapor, fuller terpene flavor, and far less wasted concentrate. A carb cap is the single most impactful upgrade for anyone doing low-temperature dabs.
The style of cap changes how it performs. Bubble caps have a rounded body and a directional airhole — the most common and most forgiving style, easy to spin and reposition; AFM's Bubble Trap, Dichro, Honeycomb, and Angry Birds series cover this tier in dozens of colorways. Directional caps have an angled airpath that lets the user push vapor and concentrate across the banger floor by rotating the cap. Spinner caps pair with terp pearls — the incoming air spins the pearls, creating a whirlpool that keeps concentrate moving across the hot quartz. Flat-top caps fit universally on most standard bangers. Terp slurper caps are sized specifically for terp slurper bangers, which have a different geometry. The 4 Point 0 Turbo Top is a dual-airflow cap built for the Tourbillon system.
A carb cap must match the banger it sits on. Compare against Quartz Nails for the bangers themselves, Terp Pearls & Pillars for the inserts spinner caps work with, and Dab Rigs for the rigs they all attach to.
The carb cap collection sorts by style. Bubble caps dominate the inventory — AFM's Bubble Trap (Blue, Fume, Green, Pink, Space Tech), Dichro Bubble Cap (Blue, Gold, Green, Red), Honeycomb Bubble Cap, and the Angry Birds Bubble Cap series — rounded bodies with a single directional airhole, the most forgiving style for new dabbers. Directional caps like the AFM Directional Carb Cap have an angled airpath for steering vapor across the banger. Spinner caps from One Trick Pony, Str8 Glass, and JAG pair with terp pearls for whirlpool airflow. Heady caps from Mothership Glass, Gordo Scientific, and Conversion Glass are one-of-one collectible pieces. OEM device caps from Puffco fit the Peak and Proxy. Specialty: the 4 Point 0 Turbo Top, a dual-airflow cap for the Tourbillon.
Three picks cover the range. The AFM Bubble Trap Bubble Cap (Blue) is the everyday benchmark — a bubble cap that fits most standard bangers, easy to spin and reposition, available in five colorways. The AFM Directional Carb Cap (Cobalt Blue) is the airflow-control pick — angled airpath for steering concentrate across the banger floor. The 4 Point 0 Glass Turbo Top is the specialist pick — dual-airflow control built for the Tourbillon banger system.
| Setup | Recommended Cap Style | Why |
|---|---|---|
| Standard quartz banger, new dabber | Bubble cap (AFM Bubble Trap) | Most forgiving, easy to spin and reposition |
| Want to steer the vapor | Directional cap (AFM Directional) | Angled airpath pushes concentrate across the floor |
| Using terp pearls | Spinner cap | Air spins the pearls into a whirlpool |
| Terp slurper banger | Terp slurper cap | Sized for the slurper's specific geometry |
| Puffco Peak or Proxy | Puffco OEM cap | Made to fit the device's heater |
| Collector piece | Mothership, Gordo Scientific, Conversion Glass | One-of-one heady glass |
A carb cap must match the banger's opening — most standard bangers take a universal bubble or flat-top cap, but terp slurpers and proprietary devices (Puffco Peak, Proxy) need cap-specific fits. Verify the banger style before ordering. Spinner caps only function with terp pearls inside the banger; bought alone, a spinner cap still works as a directional cap but loses the whirlpool effect. Glass carb caps can crack from thermal shock if dropped onto a red-hot banger — let the banger cool slightly before capping. See Cleaning Supplies for keeping caps clear of concentrate residue.
Start with the AFM Bubble Trap Bubble Cap as the everyday pick, read essential dab tools for beginners for the full setup, and check Quartz Nails to match the cap to a banger.
