Crown Nano Tank

The Uwell Crown Nano is a 23mm MTL tank with integrated anti-leak coil technology and PRO-FOCS 4.0 flavour tech. If you've been looking for a leak proof vape tank, this is built around that problem. The coils have a built-in base that seals directly to the tank body with high-density cotton, so there are no gaps where liquid can seep through to the airflow or 510 connection.

It comes with two Crown Nano coils - a 0.8 ohm at 12 to 16W and a 1.2 ohm at 10 to 12W, both MTL. The extended capacity means fewer refills, and the top-fill has an extra silicone seal for a secondary leak barrier. It connects through a 510 thread and sits flush on smaller mods at 23mm diameter. Available in 5 colours and built from 304 food-grade stainless steel.

Crown Nano Anti-Leak Coil Design

The Crown Nano's anti-leak technology is what sets it apart from other MTL tanks. Traditional tanks thread a coil into a separate base, and that connection point is where most leaks start. The Crown Nano integrates the coil and base into a single sealed unit - there's no threading gap for liquid to work through.

The high-density cotton inside each coil is specifically designed to hold liquid without letting it seep past the coil base into the airflow channels or 510 connection. Combined with the top-fill silicone seal and bottom airflow placement, the whole tank is built to stay dry. If you've had problems with vape tanks that leak during pocket carry or overnight, this is an anti leak vape tank worth trying.

Coils and Wattage

Resistance	Wattage	Draw Style	E-Liquid
0.8 ohm	12 to 16W	Warmer MTL	50/50 nic salts
1.2 ohm	10 to 12W	Tighter MTL	Higher strength nic salts

Both coils use PRO-FOCS 4.0 (Precise Optimisation of Flavour with Complete Smoothness) which spreads heat evenly across the mesh to avoid hot spots. This also helps coil longevity - even heat means the cotton doesn't burn unevenly.

Airflow and Drip Tip

Three holes in the bottom airflow ring let you dial in the draw. Fully closed gives you a tight cigarette-style pull, and opening up progressively loosens it through restricted MTL. The bottom placement keeps liquid away from the airflow path, which ties into the leak proof design.

The tank comes with a 510 MTL drip tip and accepts any standard 510 replacement tip if you want to swap it.

Why Choose the Crown Nano Tank

The Crown Nano is one of the few MTL tanks built specifically around leak prevention. The integrated coil base removes the connection point where most tanks fail, and the high-density cotton and silicone seal back it up. If you've written off tanks because of leaking, this is the one to try.

The two coil options cover tight and warmer MTL draws at low wattages (10 to 16W), and the extended capacity keeps refills to a minimum. At 23mm and 44g it won't overhang on smaller mods, and the 510 thread fits anything you've already got.
