GRAV STAX Dual-Function Inline Base
The STAX® Dual-Function Base is 7" 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 STAX® Funnel Bowl. Both joints can be blocked to focus airflow to the opposing joint using the pipe's 14mm male-female reversible glass plug.
The two lower chambers converge on an inline perc. The dual-function base can accommodate any STAX® percolator or mouthpiece and works best with approximately 2" of water.

For borosilicate glass bongs and pipes, use 91%+ isopropyl alcohol combined with coarse sea salt as a gentle abrasive. Swirl gently for 2–3 minutes.
Rinse thoroughly with lukewarm water until completely odorless. Never shock hot glass with ice water to avoid thermal micro-cracking.
