Fits any STAX® perc or mouthpiece.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 a spigot perc in line with the base's 34mm joint. The dual-function base can accommodate any STAX percolator or mouthpiece and works best with approximately 2" of water.
