FreeMax M Pro 3 Replacement Glass

One cracked glass tube and your entire M Pro 3 setup is out of action. This is the genuine Pyrex bubble glass replacement for the FreeMax M Pro 3 Tank, holding 2ml of e-liquid under UK TPD regulations. Also fits the FreeMax Maxus 2 Kit.

Heat-resistant construction with a snug O-ring seal, single tube per pack. If your current glass has a chip or a crack, this is the part. Browse more Replacement Tank Glass at Pirate Vapes.

• O-ring seated fit with no tools, no adhesive, no modification

• Sold individually so you buy exactly what you need

FreeMax M Pro 3 Replacement Glass Features

Pyrex Handles What Regular Glass Cannot

Sub-ohm coils firing at 40W to 100W through a DTL Tank heat and cool the glass dozens of times per session. Pyrex is borosilicate: its thermal expansion rate is far lower than soda-lime glass. It does not stress-crack from heat. Impact is the only real threat.

One Glass, Four Tanks

FreeMax kept the same glass dimensions across the M Pro 3, M Pro 2, Mesh Pro, and Fireluke Pro tanks. If you have upgraded through the series over the years, this single glass fits every generation. Pair it with the right Freemax Coils, and you have a fully refreshed tank section for under a fiver.

Seated Fit, No Fuss

Two silicone O-rings hold the glass between the top cap and base. No threading, no clips. Swapping takes under a minute. Inspect those rings every time you change the glass, though. A worn ring leaks.

How to Replace the FreeMax M Pro 3 Glass

Quick job. Two minutes at most.

1. Empty the tank. Vape it down or pour remaining e-liquid back into the bottle.

2. Unscrew the top cap anticlockwise. The coil usually stays on the base.

3. Slide the old glass off gently. If cracked, wrap it in a cloth first.

4. Check the O-rings on the cap and base. Wipe clean, replace if flattened or torn.

5. Slide the new bubble glass onto the base until it seats against the lower O-ring.

6. Screw the top cap back on, fill through the top-fill port, and you are sorted.

What's in the FreeMax M Pro 3 Replacement Glass Box

One Pyrex bubble glass tube. No O-rings, no coils, no tank hardware. Just the glass. If your O-rings need replacing too, check Vape Accessories for spares.

Built for the Entire M Pro Sub-Ohm Range

This glass fits any Sub-Ohm Tank in FreeMax's M Pro and Mesh Pro family: the M Pro 3, M Pro 2, Mesh Pro (all editions), and Fireluke Pro. All share the same 22mm bore and 28.15mm outer diameter.

It does not fit FreeMax pod kits, the Fireluke Solo, the Fireluke 4, or any tank outside the Mesh Pro/M Pro chassis.

About FreeMax

FreeMax built its name on mesh coil technology before most of the industry caught up. The M Pro series became one of the most widely used sub-ohm platforms in DTL vaping, and the 904L stainless steel mesh coils set a benchmark for flavour production that later brands openly borrowed from. The M Pro 3 is the current generation of that platform.

FAQs

Which tanks does the M Pro 3 glass fit?

The FreeMax M Pro 3, M Pro 2, Mesh Pro (all editions), and Fireluke Pro. Same dimensions across the full range.

Is this the bubble glass or the straight tube?

Bubble. The convex Pyrex profile that comes standard with the M Pro 3 Tank.

Does it come with O-rings?

No. Just the glass tube. Check your existing O-rings before fitting and replace them separately if worn.

Will this fit the Fireluke 4 or Fireluke Solo?

No. Those tanks use a different glass profile and diameter entirely.

How do I know if my glass needs replacing?

Any visible crack, chip, or cloudiness that does not wipe clean. Even a hairline fracture can fail under thermal stress from sub-ohm coils.
