Check the O-Rings for Damage

​If you’re a vaper, then you know that one of the most important things to do to keep your vape in good working order is to check the o-rings for damage. O-rings are vital to the proper functioning of your vape, and if they’re damaged, it can cause all sorts of problems.

So, how do you know if your o-rings are damaged? There are a few telltale signs. First, if you notice that your vape is leaking, that’s a surefire sign that something is wrong with the o-rings. Another sign is if you notice that your vape isn’t producing as much vapor as it used to. This can be a sign of a variety of issues, but it’s worth checking the o-rings to see if that’s the problem.

If you do find that your o-rings are damaged, don’t worry – it’s easy to replace them. You can find replacement o-rings at most vape shops, or online. Just make sure to get the right size o-rings for your vape, and you’ll be good to go!

Tighten the Cartridge Securely to the Battery

​As anyone who’s ever used a vape will know, one of the most annoying things that can happen is when your cartridge starts leaking. Not only is it a waste of your precious vape juice, but it can also be really frustrating to have to keep stopping to clean up the mess.

One of the main reasons that cartridges leak is because they’re not screwed on tightly enough to the battery. So, if you’re having leakage issues, one of the first things you should check is to make sure that your cartridge is screwed on as tightly as possible.

If you still find that your cartridge is leaking, even when it’s screwed on tightly, then there are a few other things you can try. One is to remove the cartridge and blow gently into the opening where the cartridge screws onto the battery. This will help to clear any debris that may be blocking the connection and causing leakage.


Every vape kit is different. Depending on the output and power of each kit, they require different coil resistance levels.

Coils with higher resistance (1.0ohm and above) produce less vapor but provide a stronger throat hit. These coils perform best when paired with 50:50 e-liquids or Nicotine Salts.​

Coils with a lower resistance (1.0ohm and below) produce bigger vapor with a smoother throat hit. These coils perform best when paired with e-liquids with a higher VG content such as 30:70 e-liquids and Shortfills. Because of the vapor production, sub-ohm coils typically have large inlet holes. As high VG e-liquids are typically thicker than other e-liquids, they are the perfect option for sub-ohm vaping. Cleaning and Drying the Device

Replacing Damaged or Worn-Out O-rings

​Vaping is a great way to enjoy your favorite e-juice flavors, but it can be frustrating when your vape starts to leak. Often, the culprit is a damaged or worn-out O-ring. Replacing your O-rings is a quick and easy fix that can help prevent leaks and keep your vape working properly.

There are a few things you’ll need to do before replacing your O-rings. First, you’ll need to identify which O-ring is causing the problem. Second, you’ll need to find the right size O-ring to replace it. And third, you’ll need to make sure you clean both the O-ring and the area around it before installing the new one.

Once you have everything you need, replacing your O-ring is a simple process. First, remove the old O-ring from the vape. Next, clean the area around the O-ring groove with a cotton swab or toothpick. Be sure to remove any debris or residue that could prevent the new O-ring from sealing properly.

Now it’s time to install the new O-ring. Simply stretch it over the O-ring groove and make sure it’s seated properly. Once the new O-ring is in place, reassemble your vape and give it a try.

If you’re still having leaking issues, it’s possible that there’s another issue causing the problem. Check all of your O-rings to see if any of them need to be replaced. It’s also a good idea to clean all of the O-rings and the O-ring grooves before installing new ones. This will help ensure that your vape is leak-free and working properly.

Inspecting the Battery Contacts

​A loose vape tank can cause your e-liquids to leak through the gaps. Make sure the fixture is closed securely and no e-liquid is leaking by tightening the top and the base of the tank. This will stop e-liquid from leaking through the joins in your tank.

Also make sure that your coil is inserted properly. Your coil creates a seal within a vape tank that stops e-liquids leaking. Unless your coils are sitting where they are supposed to, your e-liquids are likely to escape. Push your coils inside your vape kit until you hear or feel a light click – this confirms your coils are where they are supposed to be. Discarding a Faulty or Damaged Cartridge

Ensuring Proper Storage and Maintenance

​Keep your tank upright wherever possible. In addition to making it easier to accumulate dirt and dust, storing an e-cigarette on its side can deplete your e-liquid by causing it to leak into unwanted places.

By storing your e-cig in a vertical position, you reduce the risk of damaging your vape device and wasting your precious e-juice.


Before they can be made into vapour, e-liquids must be heated. Warm vapour frequently causes condensation within your chimney. But when you have not inhaled for long enough, or your e-cigarette hasn’t heated enough, e-liquids can leak into your chimney and into your mouth.


Vape kits with variable power settings should be adjusted to suit the installed coil and chosen e-liquid. All coils have optimal power ranges, and your vape kit’s power should be selected to suit this. If the power is too low for your coil, your vape kit won’t properly vaporize your vape juice and instead allow liquids to escape. By cleaning the chimney, you can get rid of any last e-liquid drops and continue vaping as normal.

If the issue is with the pen, try replacing the cartridge. If the issue is with the cartridge, try replacing the seal or cleaning the cartridge.

If you’re still having issues, it’s best to consult with a professional. They can help you figure out what’s causing the leak and get it fixed.

Poor-Quality Leaking Vape

One of the most common reasons for THC vape pen oil leakage is a low-quality cartridge.

These cartridges may be made from cheap materials that are not properly sealed, allowing the oil to seep out. If you are experiencing oil leakage from your THC vape pen, it is best to check the quality of your cartridge and consider replacing it with a higher-quality option.

Loose Connection

Another reason for THC vape pen oil leakage is a loose connection between the cartridge and the battery.

If the connection is not tight, the pressure from the oil can cause it to leak out. To fix this, simply remove the cartridge and make sure that it is properly seated in the battery. If the connection is still loose, you may need to replace the cartridge or battery.


In some cases, overuse of a THC vape pen can cause oil leakage. This is because the heat generated by the device can cause the oil to expand, leading to pressure that can cause it to leak out. If you are experiencing oil leakage from overuse, try reducing your usage or storing the device in a cooler location.

Overfill tank

You can tell by looking that almost all oil tanks will leave some space and the top will not be completely filled. This helps create a vacuum inside the can and prevents oil from leaking through the pens airflow holes.

Damaged Cartridge

If you have dropped your THC vape pen or have been rough with it in any way, it is possible that the cartridge may have become damaged. This can cause the oil to leak out, so it is important to check the cartridge for any signs of damage and replace it if necessary.

Old or Expired Oil

Finally, it is possible that the oil in your THC vape pen may simply be old or expired. This can cause the oil to become less viscous, making it more prone to leaking out. If you suspect that your oil may be old or expired, it is best to replace it with fresh oil.

Incorrect Usage

Using a THC vape pen incorrectly can also lead to oil leakage. For example, if you use the device upside down, the oil can leak out. To avoid this, always make sure to use the device in the correct orientation and follow the manufacturer’s instructions carefully. More help

Improper Storage

Finally, improper storage of a THC vape pen can also lead to oil leakage. If the device is stored in a hot or humid environment, the oil can become too thin and leak out. To avoid this, store the device in a cool, dry place and make sure to store it upright to prevent oil from leaking out.
