The XL Glass Bubble Cap is the wide version, built for the big buckets. Its job is directional airflow: seat it, turn it, and the air stream moves where you point it instead of dropping straight down the middle.

That control is what keeps a dab spread thin across the dish rather than pooling in one spot, which is where low-temp dabs lose their flavor.

📏 Why XL

A standard cap on a 30mm bucket only reaches the middle. There is dish left over on every side, and the concentrate sitting out there never gets moved.

The XL is wide enough to seal and steer across the whole surface. It fits 25mm, 30mm and 35mm buckets.

🎯 Which Cap for Which Bucket

• 30mm and up - this one. The XL Quartz Banger (30mm) is the MiniNail bucket it is built for.
• 20mm and 25mm - the standard Glass Bubble Cap is sized for those. The XL does fit a 25mm, but the standard one is the closer match.

⚙️ Specifications

• Fits 25mm, 30mm and 35mm quartz bangers
• Thick borosilicate glass
• Directional airflow - turn the cap to aim the stream
• Built for low-temperature dabs

🧠 Pro Tips

• Cap after the dab goes in, not before. You want the airflow working on concentrate that is already on hot quartz.
• Turn the cap slowly through the pull. A quarter turn is usually enough to move what is left in the dish.
• Add terp pearls and the cap spins them, which does the same job mechanically while you steer the air.
• Wipe the cap while it is still warm. Residue on the glass comes off easily then and takes real work later.

🔎 Other Caps

• Glass Bubble Cap - the standard size, for 20mm and 25mm buckets
• Glass Cyclone Carb Cap - two ports that spin the air into a vortex instead of steering one stream
• Flat Tip Dabber and Carb Cap - dabber and cap in one tool
