Geekvape Zeus Nano Bulb Glass

A single piece of Pyrex bubble glass shaped to fit the Geekvape Z Nano Tank and nothing else. The bulb profile increases your visible liquid window and gives the tank a rounder, more substantial silhouette compared to the slim straight glass that ships in the box.

Food-grade Pyrex construction handles heat cycling without cracking under normal use. Sold individually. If your Z Nano glass is chipped, clouded, or shattered after a drop, this is the genuine Geekvape replacement. Compatible with the Z Nano tank as found on the Geekvape Z50 kit. Over 18s only.

Why vapers choose this:

• Genuine Geekvape fitment ensures the glass seats flush against the tank's silicone O-rings without wobble, rocking, or leaks that come with poorly sized third-party alternatives

• Pyrex durability handles repeated temperature changes from coil heat without the stress fractures that cheaper soda-lime glass develops over time

• Increased liquid capacity at 3.5ml versus the 2ml straight glass, so you are refilling less often through the day

• Visual liquid level is easier to read through the wider bulb profile, especially with darker e-liquids where the narrow straight glass makes it hard to tell how much is left

• Cheap insurance against a cracked tank at under £3, compared to replacing the entire Z Nano tank assembly

Geekvape Zeus Nano Bulb Glass Features

Pyrex That Earns the Name

Not all replacement glass is actual Pyrex. Geekvape uses food-grade borosilicate glass for the Zeus Nano bulb, which matters because borosilicate resists thermal shock far better than standard glass. Your coil generates heat. Your liquid absorbs it. The glass sits between the two. Cheap glass cracks under that cycle. This one does not.

More Liquid, Same Tank

The bulb shape adds usable volume without changing the tank's height or 510 threading. Your Vape Tank still fits the same mods and still accepts the same coils. The only thing that changes is how often you reach for your e-liquid bottle. For daily vapers running the Z Nano at moderate wattage, that extra capacity adds up.

A Two-Minute Fix for a Broken Tank

Glass breaks. It is the most fragile part of any tank setup, and one bad drop onto a hard surface can end a vaping session. Keeping a spare glass bulb in a drawer or your carry case means you are back up and running in minutes rather than waiting for a full tank replacement to arrive. Fair enough, it is not glamorous. But it solves a real problem.

How to Replace the Geekvape Zeus Nano Glass

1. Unscrew the tank base from the Z Nano, separating the lower hardware from the glass and top cap assembly.

2. Slide the old glass off carefully. If it is cracked, wrap it in tissue first to catch any fragments. Dispose of broken glass safely.

3. Check both O-rings on the top cap and base. They should be clean, undamaged, and seated in their grooves. Wipe away any dried liquid residue.

4. Slide the new bulb glass onto the base, pressing gently until it sits against the lower O-ring.

5. Reattach the top cap and screw the tank back together. Do not overtighten. Finger-tight is enough. Let any freshly filled liquid settle for three to four minutes before your first draw so the coil wicking catches up.

What's in the Geekvape Zeus Nano Bulb Glass Box

One Pyrex bubble glass tube. No O-rings, no coils, no tank hardware. If your O-rings need replacing, those ship with Geekvape's spare parts packs or with new Geekvape Coils in some cases.

The Right Glass for the Z Nano, Not the Z Nano 2

This glass fits the original Geekvape Z Nano Tank as bundled with the Geekvape Z50 Kit. The Z Nano 2, which ships with the Aegis Mini 2 (M100) kit, uses a different glass with different dimensions.

They are not interchangeable. If your tank came with a Z50 mod, this is correct. If it came with an M100 mod, you need the Z Nano 2 replacement glass instead. Check the name printed on your mod if you are unsure.

About Geekvape

The Zeus tank platform is one of Geekvape's longest-running product lines. Starting with the original Zeus RTA and expanding through the Zeus Sub-Ohm, Zeus X, and the compact Z Nano, the series is built around top airflow engineering that reduces leaking.

The Z Nano brought that design philosophy into a smaller form factor for single-battery mods, and it remains a popular choice among vapers who want sub-ohm performance without carrying a full-sized tank. Geekvape backs the Zeus range with widely available replacement parts, including glass, coils, and drip tips, which keeps the tanks in service long after purchase.

Stock Up and Save

Glass is the one part of your tank that cannot be repaired. Grabbing a spare now means you are covered when an accident happens, not after. At under £3 per piece, picking up two makes sense.

Every order from Pirate Vapes ships same day before 4 pm in padded packaging to keep fragile items protected during transit. TPD-compliant stock, age-verified checkout, over 18s only. Free Pirate Post on orders over £25.

Conclusion

The Zeus Nano bulb glass is a straightforward replacement for the original Z Nano tank. Pyrex construction, genuine Geekvape fitment, and a bulb profile that adds capacity without changing how the tank works.

If your Z Nano glass is damaged or you just want a spare on hand, this is the part you need. Browse more Replacement Tank Glass and Vape Accessories at Pirate Vapes.

FAQs

Does this glass fit the Zeus Nano 2?

No. The Z Nano and Z Nano 2 are different tanks with different glass dimensions. This bulb glass fits the original Z Nano only, not the Nano 2 version found on the M100 kit.

What capacity does the bulb glass hold?

3.5ml. The straight glass that comes with the Z Nano in TPD markets holds 2ml. The bubble shape adds the extra volume.

Is the glass actual Pyrex?

Yes. Geekvape uses food-grade borosilicate Pyrex for the Zeus Nano replacement glass. It handles heat better than standard glass and resists thermal cracking.

Do I need new O-rings when replacing the glass?

Usually not. The existing O-rings on your tank should still seal properly unless they are visibly cracked or flattened. Check them during the swap and replace only if damaged.

Will this glass work on other Geekvape tanks?

No. It is shaped specifically for the Z Nano. The Zeus Sub-Ohm, Zeus X, and Z Nano 2 each use their own glass. They are not cross-compatible.
