The HydroLoop 16" Recycler Bong from Rock Glass is engineered for smokers who want next-level smoothness, continuous recycling action, and a clean, scientific aesthetic. Built from thick borosilicate glass, this tall recycler combines multi-stage percolation with external water pathways to deliver cool, flavorful, and splash-free hits.
Multi-Stage Filtration for Superior Smoothness
Filtration starts in the lower chamber with a Multi-Arm Tree Perc, breaking vapor into fine bubbles and providing strong initial cooling. As the vapor rises, it passes through the UFO Perc in the upper chamber, adding a dense second layer of diffusion.
From there, water is pulled into the external recycling arms, circulating continuously back into the base. This constant motion further cools the vapor, smooths out airflow, and helps prevent splashback—making every draw clean, steady, and flavorful.
Durable Build + Eye-Catching Scientific Design
The HydroLoop stands tall on a sturdy flared base for excellent stability. Its transparent scientific layout lets you see every recycling movement and perc working together, offering both performance and visual appeal.
Each piece features random color accents on the percs, base, arms, and mouth rim, making every unit one-of-a-kind. A 14mm male herb slide is included so the bong is ready for use right away.
