Add an additional water chamber to your water pipe with a 90º Ash Catcher by Herb-Iron. Ash catchers pre-cool your smoke and help keep your water pipe clean. The Herb Iron ash catcher includes two dents on opposing sides of the push bowl specifically made for the Herb-Iron ceramic heating apparatus. The dents allow you to easier press the Herb-Iron's tip into the bowl to more efficiently vaporize your flowers. This particular ash catcher includes a 90º grindless 14mm male joint.
