These Grenade Matrix HydroTube Bases are designed to have an 18mm female joint Hydrotube style Bubbler mounted on top. They can also be used with vaporizer hose /whip tubing without an adapter if desired. Just pop the tube in the 18mm male joint, your vape in the 18mm female joint and you're good to go!
They have an 18mm female joint for connection with bottomless bangers or vaporizer and an 18mm male joint for hydrotube or whip adapter. Made with a large stable base these provide good stability to your setup.
18mm to 14mm Glass adapters can be found here if needed for use with a 14mm bottomless banger.
We also have 18mm to 14mm glass reducers for adapting the top 18mm male joint to 14mm allowing Hubble Bubble bubblers and similar 14mm hydratubes to be mounted on top.
