MATERIAL Borosilicate JOINT 14mm Female USPeirce Flower DESIGNED BY Stephan Peirce
The GRAV® Upright Bubbler is 7" tall and made on 44mm tubing. Its fission downstem diffuses smoke through water and is fixed inside the bubbler to prevent damage. Its angled mouthpiece acts as a splashguard, and its lip wrap is tooled for comfort. The upright bubbler comes ready to use with a 14mm cup bowl and works best with approximately 2" of water.
