The MJ Arsenal Carb Caps are crafted to enhance the vaporization of concentrates by effectively restricting airflow and regulating internal pressure within a quartz bucket. By sealing the top of the heating surface, these specialized glass accessories allow users to vaporize materials at lower temperatures, which preserves delicate flavor profiles and significantly reduces material waste. Designed for users who prioritize efficiency and flavor, the caps provide manual control to direct air exactly where it is needed. Manufactured from laboratory-grade borosilicate glass and quartz, they offer reliable heat resistance and are universally compatible with most standard 20mm to 25mm flat-top quartz setups.
Low-Temperature Vaporization Control
By manipulating the airflow into the quartz bucket, this accessory maintains the optimal surface temperature for longer periods. This restriction lowers the boiling point of the materials inside, allowing them to vaporize efficiently without burning. The result is the production of thicker vapor clouds while simultaneously preserving sensitive terpenes. This precise thermal management ensures a highly efficient extraction process and minimizes overall material waste.
High-Heat Material Construction
Constructed from premium laboratory-grade borosilicate glass and high-quality quartz, these accessories are engineered to withstand extreme temperature fluctuations. This robust material composition ensures that the glass maintains its structural integrity over time, preventing cracking or degradation during daily heating cycles. With an average height of approximately 1.75 inches, the durable build provides a safe, cool-to-the-touch handling experience.
Directed Airflow Management
Designed with ergonomic handling in mind, these caps allow users to manually rotate or tilt the glass to target specific pooling areas inside the bucket. Styles like the Bubble or Flat caps feature a single directional airway, while the Spinner variant utilizes four specially angled holes. This multi-hole design creates a miniature vortex effect, which can spin heat-sensitive beads to distribute extracts evenly across the hot surface.
Versatile Style Options
The caps are available in multiple functional shapes to suit different preferences, including the standard Bubble, Flat, and Spinner designs. For users seeking a unique aesthetic, the Mushroom series features a sculpted glass mushroom top. Regardless of the visual style, all variants are precision-made to securely fit 20mm outer diameter buckets, while remaining compatible with most generic 20mm to 25mm flat-top setups.
