The airflow through this ashcatcher by Diamond Glass runs through a showerhead percolator with 15 d-slits that will smooth and chill your smoke or vapor to perfection before it flows into your water pipe or dab rig. Made from clear borosilicate glass with the Diamond Glass logo proudly displayed on the single chamber. An economical way to add a chamber and extra percolation to your current piece. The 18-mm male joint for connection to the water pipe is at a 45-degree angle.
