Grav Labs 18.8mm Female Octobowl

This Octobowl has a 19 mm female joint and fits any 19 mm male joint. Although this accessory is small, it will noticeably improve your smoking sessions. Designed with a glass screen, it will catch ash before it enters your pipe, without restricting the airflow. As a result, your pipe will stay clean for longer.

The 19 mm Grav Female Octobowl is designed for larger water pipes.
