What is the Aspire Nautilus 3SR Tank Tube?
The Aspire Nautilus 3SR Tank Tube is the replacement glass body for the Nautilus 3SR MTL tank. Tank tubes are the most commonly broken component on sub-ohm tanks — the glass is exposed and vulnerable to being knocked, dropped or tightened excessively. A replacement tube at £4.99 restores a broken tank to full operation at a fraction of the full tank replacement cost.
Sub-ohm tank users are recommended to keep a spare glass tube for their daily tank — it is the most likely component to need replacement and having a spare prevents the frustration of a broken tank rendering the device unusable.
- Replacement glass tube for the [Aspire Nautilus 3SR](/aspire-nautilus-3sr-tank) MTL tank — the most economical repair when the original glass breaks.
- Pyrex or borosilicate glass provides heat resistance and clarity for monitoring e-liquid level.
- Replacement tubes restore a damaged tank without the cost of a full tank replacement.
- Straightforward installation — the tube slides in and seals with the existing O-rings on the tank.
- At £4.99, significantly cheaper than replacing the full Nautilus 3SR tank at £20.99.
Replacement tank tubes: what to know
Tank tubes are made from pyrex or borosilicate glass — materials chosen for their heat resistance (high-wattage vaping can produce temperatures up to 200°C near the coil) and their resistance to e-liquid corrosives. Some e-liquids with high citrus content can stress lower-grade glass over time. Aspire uses pyrex-grade glass in the Nautilus series.
When replacing a tank tube, ensure the O-rings are in place on both ends of the tube before reassembling. The tube seals against O-rings at the top cap and base of the tank. Replace O-rings if they show signs of deformation or cracking during the repair process.
The good
- Restore a broken Nautilus 3SR tank for just £4.99.
- Pyrex glass for heat resistance and e-liquid compatibility.
- Quick repair — no specialist tools needed.
The catch
- Compatible only with the Nautilus 3SR tank — not interchangeable with other Nautilus versions.
