Uwell Tanks

Uwell tanks prove that thoughtful design can go a long way. Whether you want cloud-chasing power or a simple, flavour-driven vape, their tanks deliver it day in, day out. Well-known vape tanks, like the Valyrian 2, Nunchaku, and Crown IV, each bring something different to the table, fitting various vaping styles without compromise. These replacement vape tanks are built with everyday use in mind.

What Makes Uwell Tanks Reliable

Everything, from the bubble-glass capacity to self-cleaning vents, shows that Uwell puts practicality first. You’ll notice the solid threading and leak-resistant seals as soon as you pick one up. The top-fill systems are quick and tidy, and cleanup is a breeze. Over time, those small technical enhancements, like the spring‑loaded top cap on the Valyrian 2 or the Crown IV’s leak‑catching chamber, make daily upkeep feel smarter and more reliable.

Uwell Tanks Technology

Uwell builds its tanks around thoughtful innovations that make a real difference to your everyday vape. They’ve fine-tuned airflow, flavour, and maintenance so you spend more time enjoying and less time fiddling with your replacement vape tanks.

  • Pro-FOCS Flavour System: Found across this range, this tech recycles vapour to preserve flavour depth and stops coils from burning out too quickly.
  • Self-Cleaning Chamber: The Crown IV, Valyrian 2, and Nunchaku trap extra e-liquid inside, which cuts down on leaks and keeps airflow channels clear.
  • Top-Fill Access: Uwell’s tanks use sensible designs like 90° twist caps and flip-top lids—no threading everything off or getting elbow-deep.
  • Mesh Coil Performance: Valyrian 2 and Nunchaku use UN2 mesh coils (0.14–0.32 Ω), heating faster and giving you richer clouds and sharper taste.
  • Adjustable Bottom Airflow: Uwell tanks let you dial from a tight lung draw right through to wide-open sub-ohm lung hits without harsh transitions.
  • Tough Construction: Cartridges from this brand feature stainless steel frames, reinforced glass (Pyrex or quartz), and stout O-rings - built to last and easy to maintain.

Choosing the Right Uwell Tanks

The best Uwell tank shines in its own way, delivering either bold vapour or refined flavour, or a bit of both. Here’s a closer look to help you pick:

  • Valyrian 2 Sub‑Ohm Tank: With its bubble glass, top-flip fill, and potent mesh coils (0.14–0.32 Ω), the Valyrian 2 tank is for vapers chasing big clouds and intense flavour without leaks.
  • Nunchaku Tank: A compact 2 ml setup that punches above its weight. You get plug-and-play coil swaps and dual airflow control in the Nunchaku tank. Its UN2 mesh coils perform brilliantly around 50–80 W.
  • Crown IV Tank: Whether you choose a bubble or straight-glass tank, the Crown IV impresses with SS904L mesh or dual-helix coil options and a clean, self-wiping bottom airflow system. It’s a refined replacement tank for smooth, flavour-packed clouds.

Frequently Asked Questions For Uwell Tanks

How to clean a Uwell tank?

Unscrew the drip tip, glass, and base. Rinse everything except the coil under warm water, let it air-dry, then reassemble using fresh O-rings; there is no need to use any specialised tools.

How to replace the glass on a Uwell tank?

Remove the base, carefully push the glass out from the top or bottom, slide in the replacement tube, and double-check the O-ring seal before reassembling.
