GRAV Quartz Hourglass Banger – 14mm 90°

The hourglass silhouette on the GRAV Hourglass Banger 14mm 90 features an inward curvature that narrows toward the middle of the bucket before widening again. This shape is specifically designed to function well for cold start dabs, where concentrate is loaded before heating. The narrowed section helps keep inserts in the lower portion of the bucket, and combined with the two laser cut directional air intakes, creates a whirling tornado effect that maximizes heat distribution.

No, the standalone GRAV Quartz Hourglass Banger 14mm 90 is the banger only and does not include any accessories. A set version is also available that includes the banger along with a 20mm quartz marble and two 6mm terp pearls. The standalone banger can be paired with your own carb cap, marble, and inserts as desired.

The GRAV Quartz Hourglass Banger 14mm 90 uses a 14mm 90-degree male joint. This configuration is compatible with dab rigs and water pipes that have a 14mm female joint and a straight vertical neck. The 14mm size is one of the most common in the industry, so compatible rigs are easy to find.

Yes, the GRAV Hourglass Banger is specifically designed to work well for cold start dabs. The hourglass silhouette with its inward curvature keeps concentrate pooled in the bottom of the bucket during the heating process. The two laser cut directional air intakes then promote airflow that keeps inserts in motion as the banger reaches temperature. This design is intended to improve the efficiency of cold start technique users.

The GRAV Quartz Hourglass Banger 14mm 90 is made from 100% quartz. Quartz heats evenly, retains heat well after torching, and is flavor-neutral so it does not affect the taste of concentrates. The banger is constructed with fully fused welds and a thick gathered flat base for durability and improved heat retention.

The two laser cut directional air intakes on the GRAV Hourglass Banger are positioned to direct airflow into the bucket in a spinning pattern. When a carb cap or marble is placed on top of the banger, the restricted airflow passes through these intakes and creates a whirling tornado effect inside the hourglass shape. This spinning motion keeps inserts like terp pearls and pillars in constant motion within the lower portion of the banger, improving heat distribution and vapor release.
