Stop the Drip: Understanding Why does My Vape Leak?

Vaping has become increasingly popular in recent years as an alternative to smoking. While vaping offers a plethora of benefits, including reduced health risks and a variety of flavors, there is one common issue that many vapers face - leaking. Vape leaking can be a frustrating problem that not only wastes e-liquid but can also cause damage to your device. In this article, we will discuss the main reasons why does my vape leak and provide tips on how to fix and prevent it.  

Why is my Vape Leaking?

Leaking can be a frustrating issue for vapers, as it can result in lost e-liquid, reduced vapor production, and a mess. Understanding the common causes of leaks and how to fix and prevent them can help ensure a better vaping experience and prolong the life of the device.
  • O-ring damage
An O-ring is a small rubber ring that seals the tank and prevents e-liquid from leaking out. O-ring damage is a common cause of leaks. When the O-ring is damaged or worn out, e-liquid can leak out of the tank. O- Ring Problem
  • Solution: Replace the damaged O-ring with a new one. Avoid over-tightening the tank, which can cause damage to the O-ring.
  • Overfilling of the Tank
Overfilling the tank with e-liquid is another common cause of leaks. When the tank is overfilled, there is not enough room for the e-liquid to vaporize properly, which can result in leaking.
  • Solution: Remove excess e-liquid from the tank. Fill the tank to the recommended level, which is typically indicated by a fill line on the tank.
  • Coil Issues
Vape Leakage Issue Coil issues, such as a damaged or worn-out coil, can also cause leaks. The coil is a small metal component in the tank that heats up and vaporizes the e-liquid. When the coil is damaged or worn out, it can cause e-liquid to leak out of the tank.
  • Solution: Replace the damaged or worn-out coil with a new one. Replace the coil regularly, as recommended by the manufacturer.
  • Improper Assembly
Improper assembly of the tank can also cause leaks. When the tank is not assembled properly, it can cause e-liquid to leak out of the tank.
  • Solution: Disassemble the tank and reassemble it, making sure all components are properly aligned and tightened. Follow the manufacturer's instructions for assembling the tank.
  • High Temperatures
Vape devices may experience leaks when exposed to direct sunlight or stored in hot environments such as cars or saunas. This occurs especially with e-liquids containing less than 70% VG, as they tend to become thinner in high temperatures. The thin consistency of these e-juices can lead to leakage through the openings in the coils and seals of the device. However, leaks can also be triggered by cold temperatures, as certain components may contract and result in leakage when the vape pen is exposed to chilly conditions. Solution: Be sure to steer clear of exposing your vape to extreme temperatures, whether hot or cold, and avoid environments where temperatures fluctuate frequently.
  • Wrong E-Liquid
Nowadays, while e-liquids have become more affordable compared to previous years, they still come with a significant price tag. This leads some individuals to seek out cheaper options, often turning to blends from the black market. However, there are drawbacks to this choice. E-liquids obtained from the black market or homemade sources may have incorrect ratios of propylene glycol (PG) and vegetable glycerin (VG), as well as added fillers. If the consistency of the e-juice is too thick, it may not vaporize properly, while if it's too thin, it can lead to leaking issues. Additionally, these illicit e-liquids could contain harmful substances, posing risks to both your health and the longevity of your vaping device.
  • Solution: Be sure to purchase e-liquids from reputable and dependable sellers. Also, double-check the label on the packaging to ensure you're getting the correct juice.
When it comes to e-liquids, it's essential to use ones that are compatible with your device. For instance, if you have a high-powered device or enjoy producing large clouds, opt for vape juices with a higher VG content. VG tends to be thicker than PG, so juices with a higher VG percentage will be thicker. A blend of 50/50 or 60/40 PG to VG works well for low-powered devices like vape pens.  

Is it Normal for My Vape to Leak?

Absolutely! If you notice a consistent pattern of leakage, it's definitely a cause for concern. Leakage typically happens when the valuable e-liquid escapes the vape tank through the airflow system. In some cases, it might even seep out through the charging port. Leakage can vary from just a few drops to a complete spill of the entire tank's contents into your pockets, which can be incredibly frustrating. So, what leads to this issue? After thorough investigation, we've pinpointed several probable causes, which we'll delve into below. Let's explore them and work on resolving them effectively.  

Tips for Fixing and Preventing Vape Leaking

  • Tightening tank connections: One of the most common reasons for vape leaking is loose tank connections. Make sure that all the connections in the tank are tightened securely, including the coil and the tank's base. Use a cloth or a paper towel to grip the connections tightly and avoid overtightening.
  • Cleaning the tank: Regularly cleaning your vape tank is crucial in preventing leaks. Disassemble the tank and clean it thoroughly using warm water, dish soap, and a soft-bristled brush. Rinse the tank thoroughly and let it dry completely before reassembling it.
  • Avoiding overfilling: Overfilling the tank can lead to vape leaking. Always fill the tank up to the recommended level and avoid filling it beyond the maximum capacity line.
  • Replacing damaged O-rings: O-rings are responsible for sealing the tank's connections and preventing leaks. If you notice any signs of wear and tear on the O-rings, replace them immediately with new ones.
  • Using the right coil: Using the wrong type of coil can also cause vape leaking. Make sure that the coil is compatible with your tank and that it is installed correctly.
  • Proper assembly: Assembling the tank correctly is critical in preventing leaks. Make sure that all the parts are installed in the correct order, and avoid cross-threading when screwing the connections in place.
  • Avoiding high altitude: High altitude can cause changes in pressure, which can lead to vape leaking. If you are vaping at a high altitude, make sure that the tank is tightly sealed and that the connections are secure.
  • Avoiding extreme temperature changes: Extreme temperature changes can cause the vape juice to expand or contract, leading to leaks. Avoid exposing your vape to extreme temperatures and store it in a cool, dry place.


In conclusion, vape leaking can be a frustrating issue that can affect your vaping experience. However, understanding the reasons behind the problem and implementing preventive measures can help reduce the frequency of leaks. Explore more insights in our vape guide.
