Why Is My Vape Leaking? Understanding the Causes

 

Before learning how to fix vape leaking, it’s important to understand why it happens in the first place. The most common causes include:

 

1. Improper Coil Installation

– Loose or incorrectly seated coils allow e-liquid to escape

– Damaged or worn-out coil O-rings fail to create a proper seal

 

2. Overfilling the Tank

– Filling beyond the max line creates excess pressure

– E-liquid can flood the coil and airflow system

 

3. Temperature & Pressure Changes

– Heat thins e-liquid, making leaks more likely

– Air pressure changes (like altitude shifts) force liquid out

 

4. Worn-Out Seals & O-Rings

– Cracked or missing rubber seals can’t contain e-liquid

– Regular wear and tear degrades these components over time

 

5. Incorrect VG/PG Ratio

– Too-thin e-liquid (high PG) wicks too quickly and leaks

– High-VG liquid is thicker but may not wick properly in some devices

 

Now that we know why leaks happen, let’s explore how to fix vape leaking effectively.

Step-by-Step: How to Fix Vape Leaking

 

1. Check & Replace Coil O-Rings

– Remove the coil and inspect its rubber seals

– Replace any cracked or missing O-rings

– Reinstall the coil firmly (hand-tight is enough)

 

2. Clean Excess E-Liquid

– Disassemble your tank completely

– Wipe all components with a paper towel

– Pay special attention to the airflow base

 

3. Adjust Your Filling Technique

– Never fill past the tank’s maximum line

– Close airflow when filling to create a vacuum

– Let the tank sit for 5 minutes after filling

 

4. Store Your Vape Properly

– Keep devices upright when not in use

– Avoid extreme temperatures

– Empty tanks before air travel

 

5. Use the Right E-Liquid

– 70% VG/30% PG works best for most tanks

– Avoid 50/50 blends in sub-ohm devices

– Thicker liquids leak less in pod systems

When to Consider a New Device

 

Sometimes, despite knowing how to fix vape leaking, the problem persists because:

 

– The tank design is fundamentally flawed

– Threads are stripped beyond repair

– Internal seals can’t be replaced

 

If you’ve tried everything and leaks continue, it may be time to upgrade to a leak-resistant model like:

 

• Top-Fill Tanks (less prone to pressure issues)
• Pod Systems with sealed designs
• Leak-Proof Models like the GeekVape Zeus
