8 Times The Fun
The Octobowl by Grav Lab is designed to allow maximum airflow and prevent. The inside of the bowl contains eight small glass fingers that act as a screen, allowing for maximum airflow while preventing ash and other matters from entering the water. And the ergonomic hand hold keeps your fingers from getting burned as you slide the bowl off the pipe.
The male Octobowl by Grav Labs is designed to fit into female joint openings. The 14mm male bowl is 2 inches high and fits into 14mm female openings. The 18mm male is 2.25 inches high and fits into 18mm female openings.
Not Sure What Bowl Size You Need?
To determine the bowl size you need simply measure the slide joint opening with a metric ruler. The slide joint opening is the hole near the base of the water pipe where the downstem reaches into the water. The measurement will be either 14mm or 19mm (or, for small water pipes, 10mm).
