Why is My Vape Tank Leaking?

Before we take a deep dive into the best leak-proof vape tanks, let’s take a look at some of the reasons why your current tank might be leaking in the first place:

Drip Tip Adapters – After vaping for an extended period, you may notice E-Liquid and condensation collecting around the drip tip; this is common. You will know this is happening if you tend to tip your mod while you vape and then get E-Juice in your mouth. It’s not a full-on leak but could leave e-liquid residue in places. Removing the drip tip and giving it a quick wipe is an easy fix.

Broken Gaskets – If you find a leak in your tank, check the O-rings and gasket to make sure there are no holes or damage. If you don’t see any rips or holes on the gaskets or O-rings, it may be worth looking behind them to ensure they’re not coming from a crack inside the tank itself. This is just usual wear on vape tanks and happens over time. If you noticed damaged o-rings etc. on a brand new tank, then contact the supplier. Most tanks will come with spare o-rings in the kit and instructions on how to change them to prevent future leaks.

Not Enough Cotton –  If you’re using an RTA and building your own coils, then you are probably aware that getting the wicking of the coils right can sometimes be a challenge. Too much wick, and you may end up with a dry, flavorless vape. Unfortunately, not enough cotton wick and you will get leaking problems with juice flowing out of the airflow. Some RTAs are more temperamental than others when it comes to wicking. Others have top airflow, so they are almost impossible to leak. That’s why we’ve included some of the best leakproof RTAs in our list below.

Type of E-Liquid – The mix or ratio of VG to PG in your e-liquid may also play a part in why your vape tank is leaking. VG is a far more viscous liquid than PG (thin like water). So you may find that by vaping a high VG juice, your tank is not leaking, but if you switch to a lower VG juice (higher PG content) then the juice as a whole is thinner and easy to seep through gaps in the wick. If you are vaping juice with a high PG content, then more wick is a must.

Cracked glass – This is the easiest issue to spot, as it’s normally apparent when just looking at the tank and seeing where the leak is coming from. Sometimes just the slightest drop of a glass tank could make a hairline crack in the glass that’s hard to see, but enough to leak juice out all over your clothes. Again it’s a simple fix, as you just need to follow the manufacturers’ instructions for changing the glass tube, and a lot come with a spare in the kit.

Best RTA Tanks That Don’t Leak

Augvape Intake Dual RTA

The Augvape Intake Dual RTA has top-mounted airflow, so leaks are virtually impossible.

It’s an upgraded version of the excellent single-coil Intake RTA, but this Dual is a 26mm dual coil RTA. It has a juice capacity of 5ml or 7ml with the included extended bubble glass.

It’s super easy to build on with its postless deck and is unbelievably forgiving when it comes to wicking. So if your wicking game sucks, it’s the tank for you.

Its unique top-to-side airflow design is what makes this tank a leakproof monster. But don’t worry if you think that airflow would lead to a lack of flavor. This thing still rocks in the flavor department and delivers a smooth draw.

An overall excellent vape tank and our go-to for a leak proof design. If you want a single coil it’s baby brother the Augvape Intake RTA is just as good an option.

Why this tank doesn’t leak: The Augvape Intake has the airflow slots at the top of the tank. Like many other tanks on this list, a top airflow system is the first and best step to preventing any unwanted leaks (compared to a bottom airflow). However, this RTA also has the airflow that comes in from the top to hit the sides of the coil, and Augvape has done a fantastic job of ensuring that the airflow is smooth and that flavor is maximized. The Intake Dual RTA is not just a leak proof tank; it’s one of the best vape tanks for any vape device.

GeekVape Zeus X (Single Coil & Mesh RTA)

The GeekVape Zeus X uses mesh coils instead of standard wire. Mesh coils are known for giving out better flavor. So if you’re looking for great flavor as well as the best leak-proof vape tank, then this is the tank for you. The Zeus X is a versatile tank that delivers leak-proof technology, and when combined with GeekVape’s best mesh coil it provides outstanding clouds and flavor without any unsightly leaks. 

The Zeus X RTA is branded by Geekvape as the best leak-proof RTA, all thanks to it’s upgraded features with complex 3d top airflow design. If you are looking for a standard coil option, then the regular Geekvape Zeus RTA is also another excellent option.

Why this tank doesn’t leak: Due to the tank’s design with mesh coils, it means you need to pack it with a lot of cotton, and more wick means less chance of leaking. These mesh coils allow you to pack a ton of wick underneath them. The Zeus X also features top and top-mounted filling, which allows the air to help feed juice to the coils from above, while there are no other outlets beneath the coil for the juice to escape. The tank also features large O-ring gaskets on the top and bottom, cutting off any leaks while you are swishing around your tank.

GeekVape Zeus Sub Ohm Tank

The Zeus sub ohm tank version has the same great leak prevention technology built-in to it as its RTA counterpart. It features replaceable mesh coils and comes with 2 tank sections that allow an e-liquid capacity of either 3.5mL or 5mL.

Thanks to its impressive flavor from the excellent mesh coils, the Geekvape Zeus Sub tank claims our top spot of non-leaking sub ohm vape tanks. Geekvapes’s Z1 0.4 Ohm Mesh Coil and the Z2 0.2 Ohm Mesh Coil are included in the kit.

Why this tank doesn’t leak: This tank has a top fill and top airflow system. The coil heads are perfectly padded with cotton where the juice gets fed to the coil. There is no airflow out the bottom of the coils or tank. The juice only gets fed through the coil wick, and an additional juice has no place to escape towards the top airflow, therefore no leakage. Any juice remaining in the tank chamber eventually gets used up while vaping instead of leaking out of small holes in other places.
