MJ Arsenal Spinner Carb Cap
MJ Arsenal
The MJ Arsenal Spinner Carb Cap is a directional airflow accessory designed for use with compatible water pipes and thermal bangers. Constructed from durable borosilicate glass, it features a specialized 4-channel vortex airflow mechanism that directs air into a circular path. This continuous rotational motion is specifically engineered to spin terp pearls, ensuring even heat distribution and consistent vaporization across the heating surface. A top-located carb hole provides users with precise manual control over airflow regulation.

The MJ Arsenal Spinner Carb Cap is a targeted airflow accessory designed to improve the vaporization process on compatible water pipes and thermal bangers. Standing distinct from a traditional flat cap, this piece incorporates a specialized internal structure that manipulates air intake. It caters to users looking for even heat distribution and consistent performance across their heating surfaces. Constructed from laboratory-grade borosilicate glass, it offers durability alongside precise functionality. By directing incoming air into a circular path, it promotes continuous movement within the setup. This engineered rotational mechanics provides optimal conditions for users aiming to efficiently spin terp pearls during their sessions.
Vortex Airflow Mechanism
This cap utilizes a 4-channel vortex airflow system that distinctively alters the air path. Instead of drawing air straight down, the directional carb holes channel the intake into a continuous circular motion. This rotational force is specifically designed to spin terp pearls rapidly inside the banger. The resulting movement pushes concentrates across the heating surface, maintaining consistent vaporization temperatures throughout the process.
Borosilicate Glass Construction
Manufactured entirely from laboratory-grade borosilicate glass, this accessory is built to withstand repeated exposure to high temperatures without compromising its structural integrity. The material choice ensures a clean, unadulterated airpath. The design measures 38.1mm in height and features a minimal aesthetic complete with a laser-etched manufacturer logo, available in both standard Clear and Iridescent glass finishes.
Precision Fit and Control
The accessory is tailored with a 10mm base diameter that seats securely inside a standard bucket, locking into place during use. It is engineered to comfortably accommodate setups utilizing a 20mm outer diameter. Furthermore, users can manually regulate the internal pressure and vapor density by manipulating the top-located carb hole, offering personalized control over the airflow dynamics during each session.
