About the Geekvape Z Sub-Ohm Tank Replacement Glass 7mL – 1 Pack
The Geekvape Z Sub-Ohm Tank Replacement Glass is the official 7mL bubble glass tube for the Geekvape Z (Zeus) series of 26mm tanks. Sold by Geekvape as the Z replacement bubble glass, it fits the original Z Sub-Ohm Tank as well as the Z Sub-Ohm Tank (2021), Z Sub-Ohm SE, Z Sub-Ohm Tank 5, Z Fli and Z Fli 2 tanks, plus the ZX and ZX II RTAs. The bulb profile expands the tank to a 7mL fill, well above the 5mL capacity of the straight glass that ships pre-installed on the Z Sub-Ohm Tank.
The tube is a clear, heat-resistant glass part made to Geekvape’s own tolerances, so it seats in the tank’s O-ring grooves without gaps or leak points and keeps the e-liquid level fully visible. Installation takes a minute with no tools: unscrew the tank from the device, remove the top cap and base to free the glass, slide the new tube into place and reassemble. Geekvape notes the glass should be clean and dry before fitting, and that the final capacity can shift by roughly 0.5mL depending on which Z-series tank it is used on.
Each pack contains one 7mL bubble glass tube. Glass is the part of a sub-ohm tank most likely to crack from a drop or a knock, and a cracked tube takes the whole setup out of service until it is replaced. Keeping spares on the shelf turns that into a quick over-the-counter fix, and the larger 7mL bulb is also a popular upgrade for Z Sub-Ohm owners who want fewer refills, making this a steady repeat seller alongside Z-series coils.
