Most leaking cannabis distillate cartridges can be fixed without replacing the hardware. Clear the airway, wipe the threads and contacts, tighten the mouthpiece and base by hand, and store the cartridge upright. If the glass or plastic body is cracked, the o-rings are damaged, or oil keeps coming out after these steps, replace the cartridge.

What causes distillate cartridges to leak
Distillate is thick and moves with heat and pressure. A cartridge can leak when the oil thins, when pressure builds inside the tank, or when a seal fails.
what are cannabis distillate carts made of
- Temperature swings change pressure inside the cartridge and thin the oil.
- The cartridge sits on its side, so oil pools against a seal.
- The mouthpiece or base works loose.
- A clogged airway builds pressure and pushes oil out.
- The cartridge was overfilled.
- The battery runs too hot or the user draws too hard.
- An o-ring or seal is worn or cracked.
Check the cartridge before you fix it
- Remove the cartridge from the battery.
- Set the cartridge upright and inspect the body for cracks.
- Wipe oil from the threads, base, and contacts with a dry cotton swab.
- Look into the mouthpiece for oil or a clog.
- Feel the mouthpiece and base for looseness.
How to fix a leaking distillate cartridge
- Place the cartridge upright in a cool room for 15 to 30 minutes so oil can settle.
- Wipe the outside of the cartridge with a dry lint-free cloth.
- Tighten the mouthpiece by hand.
- Tighten the base by hand.
- Warm a clogged airway by holding the cartridge in your hands for 2 to 3 minutes.
- Take short draws at the lowest battery setting that makes vapor.
- Stand the cartridge upright between uses.
When to replace the cartridge
Replace the cartridge if the leak does not stop after one cleaning and upright rest. Do not keep using hardware with a damaged body or seal.
