Why Does My Vape Tank Leak?
Before learning how to fix a leaking vape tank, it’s important to know why leaks happen. Understanding the problem makes it much easier to solve.
Here are the most common reasons vape tanks leak:
- Overfilling the tank
- Damaged O-rings or seals
- Using the wrong coil or poorly installed coil
- Worn-out cotton inside the coil
- Thin or watery e-liquid
- Temperature changes causing pressure buildup
- Keeping the vape tank on its side for too long

Step-by-Step Guide: How to Fix a Leaking Vape Tank
Let’s go through the practical steps you can take when your tank starts leaking.
Step 1: Check the O-Rings
O-rings are the small rubber seals that keep your vape tight. If they’re worn out, broken, or missing, juice will leak.
How to fix it:
- Take apart your tank.
- Inspect the rubber rings.
- Replace damaged O-rings with spares (most vape kits include extras).
Step 2: Make Sure the Coil Is Installed Correctly
Sometimes leaks happen because the coil isn’t screwed in properly.
How to fix it:
- Remove the coil.
- Wipe the area clean with a tissue.
- Screw it back in firmly, but not too tight (overtightening can damage threads).
Step 3: Don’t Overfill Your Tank
If you fill your tank past the maximum line, the liquid has nowhere to go but out.
How to fix it:
- Fill only up to the marked line.
- Leave a small air pocket for pressure balance.
Step 4: Store Your Vape Upright
Leaving your vape sideways in your pocket or bag increases the chance of leaks.
How to fix it:
- Store your device upright whenever possible.
- Use a vape case if you carry it in your bag.
Step 5: Use the Right E-Liquid
If your juice is too thin (high PG ratio), it may seep through the coil and leak out.
How to fix it:
- Choose e-liquids with more VG (vegetable glycerin) for thicker consistency.
- Check your coil’s recommended juice ratio.
Step 6: Watch for Flooded Coils
Sometimes coils get flooded with too much liquid, causing leaks.
How to fix it:
- Remove the coil and blow through it into a tissue.
- Prime the coil again before reinstalling.
Step 7: Adjust Airflow Settings
If your airflow holes are wide open, juice can escape.
How to fix it:
- Close the airflow slightly.
- Keep airflow balanced with your wattage settings.
Pro Tips to Prevent Leaks in the Future
Learning how to fix a leaking vape tank is great, but prevention is even better. Here are easy tips:
- Always prime new coils before use.
- Don’t chain-vape too hard—it can flood your coil.
- Clean your tank weekly with warm water.
- Replace coils every 1–2 weeks.
- Avoid extreme temperature changes (like leaving your vape in a hot car).
