FreeMax Fireluke 2 Bubble Glass

One piece of curved pyrex that stretches your tank from its standard capacity up to 4ml. The FreeMax Fireluke 2 bubble glass drops straight onto the Fireluke 2 tank using the existing O-ring grooves; no tools required.

Heat-resistant borosilicate construction sized at 28mm x 18mm, built to handle sustained high-wattage DTL Tanks sessions without cracking. One glass per pack. Over 18s only.

Why vapers choose this:

• Fewer refills throughout the day. The curved shape holds more juice than the straight glass, which matters at sub-ohm wattages

• Genuine FreeMax dimensions. Matches the Fireluke 2 and Fireluke 3 o-ring seats exactly

• Borosilicate pyrex. Handles thermal stress from high-wattage mesh coils without fracturing

• Cheap to keep spare. A backup costs less than a coffee

• Zero performance change. Same airflow, same coil fit, same wicking. Just more liquid between fills

FreeMax Fireluke 2 Bubble Glass Features

More Capacity Where It Counts

Running a Fireluke 2 at 60W or above with a mesh coil burns through liquid quickly. The standard straight glass means constant unscrewing. This bubble replacement stretches the interval between refills without adding bulk. Practically speaking? Fewer interruptions when the coil is hitting well.

Borosilicate Survives What Soda-Lime Cannot

Cheap glass cracks under rapid temperature swings. Borosilicate handles thermal shock far better, which is why FreeMax uses it across their tank range. If you have ever had a glass split mid-session and leak across your mod, the material upgrade makes sense.

Same Seals, Wider Middle

Top and bottom diameters match the straight glass exactly. The curve sits only in the midsection. Your existing O-rings seat where they always did, and there is no change to airflow or FreeMax Coils performance. No leaking if it did not leak before.

Fits the Fireluke 3 Too

FreeMax carried the same glass seat dimensions across from the Fireluke 2 to the Fireluke 3. One bubble glass covers both tanks. Worth knowing if you run either.

The Spare You Will Eventually Need

Tank glass is fragile. One knock against a desk edge, one drop from pocket height. Having a replacement on hand means your setup is never out of action waiting for a delivery.

How to Replace the FreeMax Fireluke 2 Bubble Glass

Two minutes. No tools.

1. Empty the tank or vape it down. A dry swap prevents spills.

2. Unscrew the top cap and set it aside. Grip the base and slide the old glass off the lower O-ring. Twist gently if it resists.

3. Wipe the O-ring grooves on both the cap and base with a dry cloth. Old residue here causes leaks with new glass.

4. Slide the bubble glass on from the base upward until it seats snugly against the lower O-ring.

5. Reattach the top cap finger-tight. Let the O-rings seal it, not force.

6. Fill with e-liquid, wait three to four minutes if the coil ran dry, then vape at your usual wattage.

What's in the FreeMax Fireluke 2 Bubble Glass Box

One bubble glass at 4ml capacity. No spare O-rings, no coils, no drip tip. Your existing tank O-rings should seat the new glass unless they are visibly cracked or flattened.

The Right Glass for FreeMax's Fireluke Sub-Ohm Tanks

Built for the FreeMax Fireluke 2 and FreeMax Fireluke 3 sub-ohm tanks. Both share the same glass seat dimensions.

Does not fit the original Fireluke, the Fireluke 4, or any FreeMax pod system like the Marvos or Maxus range. Different housing entirely. Check the engraving on your tank's base ring if you are unsure which model you own.

About FreeMax

FreeMax made their name through mesh coil development. The Fireluke 2 introduced their tea fibre cotton wicking system, a design carried into later tanks and coil platforms.

 That focus on coil innovation built the brand a loyal following among DTL vapers who prioritise flavour and coil longevity.

Glass is the one part of your tank setup that breaks without warning. Picking up a spare alongside your next coil order means you are covered when it happens, not scrambling for a replacement.

FAQs

Does the bubble glass fit the Fireluke 3?

Yes. Same glass seat dimensions on both the Fireluke 2 and Fireluke 3.

How much liquid does the bubble glass hold?

4ml. Noticeably more than the standard straight glass.

Will this fit the original Fireluke?

No. Different dimensions entirely. This glass is for the Fireluke 2 and 3 only.

Do I need new O-rings when swapping?

Usually not. Replace them only if they look cracked or flattened.

What e-liquid works best in the Fireluke 2?

High VG blends at 70/30 or above. The Fireluke 2 is a sub-ohm DTL tank. Thin 50/50 liquids can flood the coil and cause spitting.
