Cartridge Trouble? How to Fix Leaks, Clogs and Weak Hits

Vape cartridges have become one of the most convenient ways to enjoy oils and extracts. They are compact, discreet and very easy to use, making them perfect for vaping on the go. Even so, the most reliable hardware can occasionally run into issues.

Few things are more frustrating than pulling your vape out of your pocket to find a sticky leak, or taking a puff only to feel like you are trying to inhale through a blocked straw. The good news is that most problems, whether it is leaking, clogging or weak hits, can be sorted with a bit of simple troubleshooting.

Here is a clear guide to help you fix the most common cartridge problems and keep your sessions running smoothly.

Dealing with Leaking Cartridges

A leaking cartridge is easily one of the most annoying issues. It creates a mess, wastes oil and can damage your battery if ignored. If you spot oil around the glass or on the battery connection, it is important to act quickly.

Why do cartridges leak?

Temperature Changes:
Cartridges often leak when exposed to heat. Leaving your vape in a hot car or direct sunlight can thin the oil, causing it to seep through the airflow holes.

Overfilling:
If you fill your own cartridges, adding too much oil can build pressure and push liquid out.

Physical Damage:
A small crack in the glass or a damaged seal will almost always cause leaks.
How to fix it
Use a cotton bud dipped in a little isopropyl alcohol to clean the battery connection and
the bottom of the cartridge. This prevents the oil from damaging the device.

Moving forward:

• Store the cartridge upright to keep the oil near the heating element.
• Avoid over-tightening the cartridge, as this can distort the sealing ring.
• Keep it away from heat whenever possible.

Unclogging a Blocked Airway

Clogs are very common, especially in cold weather or if the cartridge has been sitting unused. You inhale but get little to no airflow.

Why do cartridges clog?

Most clogs are caused by condensation inside the airway. Vapour cools and settles back into the tube as thick oil, eventually hardening and blocking the path. Cold temperatures and high-viscosity oils also make the problem worse.

How to fix it

The Warm-Up Method:
Gently warming the cartridge often solves the problem. Hold it in your hand for a few minutes or use a hairdryer on a low setting. If your battery has a pre-heat feature, run it once or twice.

The Paperclip Method:
If the clog is stubborn, use a straightened paperclip or safety pin and carefully insert it into the mouthpiece to clear the blockage.

Solving Weak Hits

A weak hit happens when the device fires but produces very little vapour. It can make the entire experience feel flat and unsatisfying.

Why are the hits weak?>

Low Battery:
A nearly empty battery may not supply enough power to fully vaporise the oil.

Dirty Connections:
Dust, pocket lint or a small amount of leaked oil can disrupt the electrical contact.

Air Bubbles:
Sometimes an air bubble forms near the intake hole, preventing oil from reaching the coil.

How to fix it

• Charge the battery fully, even if it appears to have power.
• Clean the connection plate on both the battery and the cartridge.
• If an air bubble is blocking the wick, gently warm the cartridge or leave it upright for an hour so the oil settles.

Preventative Measures

Avoiding problems is always better than fixing them later. To extend the life of your hardware:

• Store your vape pen upright.
• Keep it at room temperature and away from extreme heat or cold.
• Take gentle draws to prevent excess oil being pulled into the airway.

Final Thoughts

Knowing how to fix leaks, clogs and weak hits is incredibly useful, but the quality of your hardware also plays a major part in how often you face these issues. Poorly made cartridges are far more likely to leak, clog or fail. For a smooth, dependable experience, it is worth investing in high-quality, verified hardware.
