The high quality Freemax Replacement Bubble Glass Tube is designed for the Fireluke 2 tank that also comes with the Freemax Twister 80W VW Kit.
There are 2 options so pick carefully:
The 4ml bubble glass is compatible with the Fireluke 2 tank that initially came with the TPD 2ml straight glass so pick this if you had a straight 2ml glass when first bought.
The 5ml Bubble glass is compatible with the Fireluke 2 tanks that initially came with bubble glass already on so pick this if you had a bubble glass when first bought.
Material: Pyrex Glass
