SMOK Bubble Glass is a replacement or upgrade glass tube made of durable borosilicate/Pyrex, designed to expand the e-liquid capacity of compatible SMOK tanks compared with standard straight glass. By bulging outwards in the middle, the bubble shape gives more internal volume while maintaining the same top and base diameter for compatibility and easy fitment.

Key Features

Increased e-liquid capacity — expands tank capacity to 5 ml, 6.5 ml or even 8 ml depending on model, allowing longer vaping sessions between refills
Pyrex / borosilicate glass construction — heat-resistant and robust for consistent performance with sub-ohm coils and high-VG e-liquids
Plug-and-play replacement — slides or screws into the existing tank chassis without modifying base or top parts
Leak-resistant sealing — carefully engineered glass O-rings and tolerances ensure a secure fit and leak prevention
Wide compatibility with SMOK tanks — available for many popular models (TFV-series, V-series, Baby-series etc.) so retailers can cover many customer needs

Usage & Care Tips

Ensure seals and O-rings are correctly seated when installing the glass — improper fit can cause leaks or poor airflow
Use high-VG e-liquids with sub-ohm coils for best performance and wick saturation
Inspect glass regularly for cracks or wear; replace immediately if damaged to avoid leaks or safety risk
Clean with warm water and soft cloth; avoid harsh chemicals that may degrade seals or glass clarity
