The GRAV® Dual-Function Water Pipe is 13″ tall and made on 44mm tubing. Its twin intake chambers are designed to accommodate both plant matter and plant extract consumption. The left chamber features a 14mm male joint, fitted with a 14mm female domeless nail made on heat-tolerant quartz. The right chamber features a 14mm female joint, fitted with a 14mm Taster® bowl. Both joints can be blocked to focus airflow to the opposing joint using the pipe’s 14mm male and female reversible glass plug. The two lower chambers converge on an inline perc, which leads to a circle perc and tapered mouthpiece. The dual-function water pipe comes ready to use with a 14mm female quartz domeless nail, a 14mm Taster® bowl, and a 14mm reversible glass plug and works best with approximately 2″ of water.
