GRAV 12" Upline Bong

Grav Labs

The Upline® Water Pipe is 12" tall and made on 38mm tubing. Its vertical downstem catches ash in the base of the pipe. Its ladder perc restrictions create bubbler chambers that wash and filter smoke as it climbs the pipe, and its upper chamber and angled mouthpiece function as splashguards.

The Upline® Water Pipe comes ready to use with a 14mm Octobowl and works best with approximately 1" of water.
