Why Is My Vape Leaking?

One of the most common problems that vapers face is leakage or seepage of e-juice from their tanks or coils. Not only can this be messy and wasteful, but it can also affect the flavor, performance, and safety of your vape.

1. Overfilling or Underfilling

One of the most common causes of vape leaks is overfilling or underfilling your tank or pod.

  • If you fill your tank beyond its capacity, you may create pressure and force the e-juice to escape from the airflow holes or the mouthpiece.
  • On the other hand, if you do not fill your tank high enough, you may not create a proper seal between the coil and the tank, which can allow air to enter and displace the e-juice.

How to fix it?

To avoid these problems, make sure that you read the instructions for your vape, and use the proper filling method. Also, always leave some space for air.

2. Damaged O-Rings or Seals

The O-rings or seals in your tank or coil are responsible for creating a tight and secure connection between the different components of your vape.

Over time, these O-rings or seals may become worn, cracked, or missing, which can compromise their function and allow e-juice to leak out.

How to fix it?

To check if your O-rings or seals are intact, you can visually inspect them and gently wiggle your tank or coil to feel for any looseness or play. If you notice any damage, you can replace the O-rings or seals with new ones that match the original specifications.

3. Loose or Faulty Components

Another possible cause of vape leaks is loose or faulty components. Such as

  • a loose or crooked coil
  • a loose or damaged glass tube
  • or a loose or faulty drip tip.

These components can prevent your vape from forming a tight seal and allow e-juice to escape from the gaps or openings.

How to fix it?

You can tighten or adjust these components using the appropriate tools or techniques. Or you can replace them with new ones that fit your vape.

4. Temperature or Pressure Changes

Vaping involves heating and vaporizing e-juice, which can create changes in temperature and pressure within your vape. These changes can cause the e-juice to expand, contract, or vaporize unevenly, which can lead to leaks or seepage.

How to fix it?

To minimize this effect, you can try to avoid extreme temperature changes or high altitudes. Or you can adjust your wattage or airflow settings to match the e-juice and the conditions.

5. E-juice or Coil Issues

The type and quality of your e-juice or coil can also affect the likelihood of leaks.

  • If your e-juice is too thin or too thick for your coil, it may not vaporize evenly and may leak from the airflow or wick
  • If your coil is clogged or burnt, it may not absorb or vaporize the e-juice properly, which can cause it to leak or taste bad.

How to fix it?

You can choose a compatible e-juice or coil, or you can clean or replace your coil regularly.

6. Improper Storage

How you store your vape can also lead to leaks. If you leave your device on its side or upside down, it can create pressure that forces the e-juice out of the tank.

How to fix it?

To prevent leaks, store your vape upright in a cool, dry place.


Vape leaks can be caused by various factors. By understanding these causes and applying some preventive or corrective measures, you can minimize or eliminate the risk of leaks. Also, you can enjoy a more satisfying and safe vaping experience. Remember to always read the instructions, choose quality components, and maintain your vape regularly to avoid leaks and other complications.
