The first step to fixing a leak in your vape pen is to identify the reason for the leak. The connection of the atomizer to the vape mod may not be secure. Check out the 510 connection on both, make sure they’re clean and undamaged, and then securely screw them together. If that’s not the issue, you may have a broken O-ring, which could be letting vape juice leak out. You should also be sure that your tank isn’t damaged. If it is, the only way to fix the leak is to replace it. If all the equipment is in good working order, be sure that you never leave the tank on its side, make sure there isn’t juice in the chimney of the atomizer, and be careful when filling your tank with liquid. If you keep having problems with leaks, come in and talk with a Kure associate, who can help you find out what’s causing it.
